Strike CNC (My first CNC router)

Those speakers look fantastic! If they sound as good as they look I think you've got a winner:dance:

The CNC looks great too. Compared to what I payed for my 1000x600mm Heiz, I personally think you got a bargain. And only after reading this, I now know what everyone is on about concerning supported rails. the Heiz X-axis is running round 22mm guides over a metre and you can see them flex upwards when plunging. Mind you, i've had it for 4 years now & I know what it is capable of. I think I payed about £4k for it without any enclosure :eek:, but then again it paid for itself doing it's first job.

I hope you have fun with it & I'd be interested how you fare with the Kress cutting wood. The first job I did in oak ate the brushes out of the Kress in no time using a 6mm slotter.

HI
I'm glad you got the machine in & your right it does weigh around half a tonne & nearly all of the weight is in the CNC router itself this gives the forum users some idea of just how rigid our CNC routers are even our standard range of wood CNC routers are all this rigid with a similar size to weight ratio relative to size , on the other hand our metal cutting CNCs are even heaver , for instance we are manufacturing a small CNC router for a customer at the present his design brief was for machining 20-40mm aluminium plate it has a 860x660 cutting bed & this weighs nearly 400KG without any base the spindle alone is 12KG.
We do want forum users to realise the enclosed CNC router in this thread was manufactured for this client with a particular job in mind the design brief was for routing thin MDF (not 25mm ) for his amazing high end speakers (& they really do look quite spectaculare) please bear in mind this was a bespoke CNC this machine was never designed for use on cutting aluminium or a heavy DOC only for the job in hand so
flexing will not be a problem.
When a customer enquires about a CNC for a particular job we always make recommendations to the customer to be sure they have the right machine for the job its needed for & within there budget we do go the extra mile to satisfy our customers needs as Shinobiwan will agree.
We always pass on the savings direct to the customer to keep the manufacturing costs down for the client's budget, if one of our standard models are not suitable we can tailor make a package suitable for the clients needs but still keeping our prices very competitive just because it is a bespoke package we do not inflate the price as other industries do ,we also use good quality components this means our profit margins are smaller but the machines are of much higher quality for instance we could of used cheaper perspex for the enclosure but we used 4mm lexan polycarb as it is higher quality & also a lot safer as it will not shatter we adopt this though process within all our design elements
best wishes

[QUOTE=JAZZCNC;27824]Ah ok slightly better than feared thou at this width extra bracing would be my prefered choice.

Hi the gantry back support on this model is 30x180mm heavy gauge we have several gantry options available for the customer to choose from
30x180mm
30x200mm
30x300mm
40x200mm
40x300mm
60x320mm

we also have a range of gantry uprights available
40x120mm
40x160mm
40x320mm
60x320mm
80x320mm

Our machines do weigh a great deal even our standard models are very heavy which is why they are so rigid no additional bracing is needed on this model they really are solid, but i do understand your concern as you just cannot see from the pictures but once you see them in the flesh "so to speak" its only then you get some idea of how rigid they are customers are always surprised by the weight of the machines.
As the customer you can virtually design your own custom CNC we us by choosing from our range of components to get a truly customised CNC router to your own spec. We have supplied a customised M series of the PRO 660x660 CNC to 2 engineering firms to replace there small CNC mills once they seen what our metal range of CNC routers can produce & for a fraction of the price of a CNC mill there sold ,our 3 phase 5HP & 7HP water cooled spindles chew through aluminium like butter & you can high speed machine with them too cutting production runs down significantly ,one client has been running his older one for the past 26 months machining aluminium all day 6 days a week & its still going strong the customer has since purchased another unit this time with full enclosure i do have permission from the company to use pictures of the components they machine with the CNC if anyone's interested seeing them we are currently archiving a selection of customers work to be placed on our new website the only draw back with the M series of machines is they are incredibly heavy even the small models are obscenely heavy to give you a idea 4 people cannot even pick up the small STK M series & this only has a 660x660 cutting bed & stands 1700mm tall

all the best

WOW! They are beautiful.

Ok first off PLEASE PLEASE don't under estimate the knowledge and expereince of some of the people you are speaking to here on the forum. I know exactly the weight and strength of the materials you use because I use them also.! . . BUT . . . There's a difference between material weight and mechanical stength.!
My reference to bracing had nothing to do with the material weight or choice and everything to do with the structural bracing.! . . . Which IMO at this size and proportions it's lacking.!

I agree 110% regards building the machine to do an intended job. . BUT . . in this case while YES it will fullfill the "Brief" it could have been so much better for so little more.!! . . Or better put you spoilt the broth to save a pinch more salt.!!

Given the full picture regards componets then with a bit more bracing (Esp the BED) and a REAL Z Axis then this machine could handle most jobs and materials upto Aluminium with good usable DOC.! . . .As it is now it will always be lacking.!!

My view and feelings regards machines built in this manner with these materials is that they are built purely with ease of build to extract maximum profit using off the shelf products. This often leads to comprimise, whether that be finacial or strength, they generaly lack in one or the other.!

IMO given the fact that at £3860(taking away the £600 for the enclosure) and the very fact that building this machine how you do requires very little equipment other than a decent drill press and could be built in just a few days then you are still making very good profit. Certainly enough to give a better Z axis using at least supported round rails and couple more piece's of profile for the bed.!!. . . . This would make the machine capable of so much more.!!

I wish you every success and please don't take my comments as a personal attack,.they are observations and MY OPINOINS gained from my experience building machines for my self and others and which I was invited to give (And feel should be said for the sake of others). I fully understand the need for profit being in business 0ver 25 years my self but some times saving that "Pinch of salt" really does spoil the soup IMO..!!!

Personally I like a lot of dead weight, but that's just me. It looks wonderful, if I needed a router I'd buy one :smile:

The proof of the pudding will be in the eating. Do we get a movie?

Yep me too Robin if it's used correctly. . . . As we know Mass can be your friend. It also weddles the weak bits out pritty quick.!!

Also forgot to say LOVE THE SPEAKERS. .:toot:

Hi Jazz

Its would have been nice to have even more for my money but I already got a lot for £4.5k.

Commercially I couldn't find a better deal. Even shipping a Chinese machine would have been more expensive after shipping and taxes.

Here's a couple of examples I looked at:

http://www.ebay.co.uk/itm/Leasing-De...ht_1330wt_1396
Marchant Dice were wanting £5.5k for this desktop model with no base or enclosure, no hiwin on the X, no Dual steppers on the X, smaller alu profiles, smaller cutting area.

http://cnc-step.de/en/products-cnc-r...lling-machines
The closest spec Heiz machine is the S-1400/T at around £8k once you add the base but its still not as well specified. It has awkward bed size that doesn't accept 4x4ft, there's unsupported rails on the Z and Y, no enclosure, and I'd say its generally of a lighter construction.

Did I mention that £4.5k also included delivery on the back of a HGV? That had to have cost around £200-300. The old man is HGV driver and they don't work for nothing. I consider your comments very useful and food for thought. Maybe strike will integrate the suggestions as standard but there's no denying the price would go up.

As for my machine I consider it a starting point. Looking at the Z axis its relatively easy to replace the unsupported rails with hiwin. Its a matter of carefully measuring, marking and then drilling and tapping a few dozen holes. So its not like I'm stuck with this forever. You suggestions to firm up the table are good one's and could be done easily too. For now I'm going to use what I have and as I start to feel the need to upgrade things I've got that option, especially with folks like yourself who have a lot of knowledge in this area.

Would it possible to visit you Jazz? Or someone else near Chesterfield to chat about these things and look at your setup? I know very little and that would be a huge boost for me.

EDIT: Thanks for the comment on the speakers :)

Hi i do invite constructive criticism

As said this was a custom machine for the customers design brief we did offer the customer supported rails as they said in previous posts we can only supply the customer with what they can afford & this machines fits the design brief for the job in hand for the customers budget & please remember the 600.00 for the enclosure included the materials for the much lager base needed to house the enclosure
& i really do not think you can make this machine in a couple of days with only a drill press & if you could i for one would not want a machine made with a drill press in a garden shed even in a tool room that was rushed to be built in a few days our machines are manufactured with a range of heavy duty equipment including CNC mills , manual bridgeport mills ,large colchester lathes to mention but a few & these are only the tool room machines not the manufacturing area we are engineering company by trade with a fully equipped manufacturing facility as well as the tool room we also have the display unit , there are also a lot of other factors in price including the free delivery for this machine at a cost of £290.00 incl VAT

We did expect to receive some comments from others & some competition & i do welcome it but this & please JAZZ i do not want to seem confrontational this machine was not supposed to be used for a wide range of materials as it was made to the customers design brief for his amazing speakers & budget
as i said we are currently manufacturing x5 machines at present with one of them a 8x4" 4 axis CNC router with this customer we did not offer them the upgrade but only gave then the choice of 20-25mm hiwin rails as a machine of this size in our opinion can only run on the profile rails one of these these machines are nearly ready & i will post pics & yes you will see this one has a heavier duty bed for the job it is designed for

Please i do not want to offend & i am not underestimating your knowledge as you use extrusion regularly then you also know all suppliers of extrusion have different grades one company's heavy grade is another company's standard grade or even light grade we have tried 7 companies from the UK & know ours come from Germany

We have many upgrades available & the customers have the choice to upgrade or not it is ultimately down to the customers budget so please bear this in mind but i do welcome your comments
best wishes

That's the plan once I get it up and running. There's a couple of jobs to do before that can happen:

• Dust extraction. Gotta cut a hole the top of the enclosure and plumb this in.
• The doors at the rear need modifying as I changed where the machine was going at the last minute and didn't want to hold up the machine any longer. Without the mod its difficult to open the doors because of limited space.
• I bought one of the 3HP Chinese water cooled spindle & vfd packages off ebay and it arrived yesterday so now I have the dilemma of choosing whether to get up and running quickly with the Kress or wait for some mounts and install the spindle/vfd combo.

Here's the door mod which will roughly half the distance required from the wall and will allow me to get in at the back for clamping, cleaning etc.

Hey Jazz, I'm a gnats left bollock away from signing a cheque to buy one of these 6040 routers from China.

Do you want to give me a quote on a better one or at least more bang for the buck ?

Ah ah if you seen my machine you'd say WTF how dare you speak.! . . . Thou It's more a case of judge me on what I do not what I do it on. . LoL . . It's not pritty but it's built very very strong and accurate.

To be honest I'm not keen on visitors(got my reasons which I won't go into on here.) but I'm more than happy to visit you and discuss or help things with your machine.

Regards the WC spindle you have obvisously felt the weight difference from the Kress and I'm sure this will have an impact on the Z axis the way it's setup at the minute.
I honestly feel that you'll end up wanting to change this sooner rather than later when you get more into CNC and all the wonderful opertunity's it presents.

By the way I'd go for the WC straight away, they difference in noise alone is worth the trouble. The fact it makes the kress look like a toy is just a bonus.!!

Difference in noise isn't as great as some think.
True the WC spindles are quiet, quieter than my air cooled high speed spindle but in use the noise of the cutter in the material is far higher than the noise of the spindles.

I do agree though that the Air or Water Cooled spindles are far superior than the Kress units and I have used all three.

Ah ah . . . Now You Old Bastard(Said Jokingly & Warmly) I know, you know, I know that you know your just taking the PISS and I can't match our little Oriental friends on price. . . Easy enough to make a better one as you know but you could easily do that your self now can't you. .:whistling:

If your serious then PM me. . . . You even have my Email.???

it seems my posts are not being listed on the forum Hmm?

i did post several replies but they went to the moderators , i do not underestimate your knowledge but would like to see the pictures of the machines you designed & built ,your comment regarding you can build this machine with a drill press in a few days is highlighted & to be commended but i personally would not like to receive a CNC router used for precision machining that i payed good money for made with a drill press let alone made in a few days , this would be the difference between us we do this for a living & intimately know each component & there limitations that comes with the experience gained from designing & testing machines across multiple platforms to weed out all the bugs any CNC design must go through countless revisions to fine tune the design ,first & foremost we are a engineering company with a manufacturing facility that houses CNC mills , manual bridgeport mills & large colchester lathes & this is just in the tool room used for our jigs ,we know the tensile strength of each beam & have run hundreds of tests with the various sizes over the years so we can recognise the material structural limits ,the support you speak of are directly proportionate the the integrity of the beam used & as you use extrusion you will also know there are various suppliers & one suppliers heavy grade is an other's light grade we have tried & tested extrusion from 7 of the UK suppliers & know our extrusion comes from Germany i do fear you may be thinking it is a lighter grade than it actually is.

Another point is the heiz models these use unsupported rails on all axis even at 1400mm long they also have no where near the support ours have & yet they have a great pedigree & reputation we have only got to this point by endless testing of each machine in this range & please remember we offered this customer the hiwin supported rail upgrade we can only go with the customers decision & budget there is nothing currently in this price range for this size of machine & the price is very competitive also one does have to question your motives behind your criticism towards the machine whilst also trying to make a sale on this thread of supplying one of your own CNC routers to another user this speaks volumes
i would also of understood your concerns if this was a general CNC router but it was not as it was for for the customers particular design spec of machining these high end speakers
i do not wish to cause offence only the chance to reply
pictures of your work would be appreciated for us all to see your own machine

Hey John If I did this would you pay me £405 to deliver it from Barnsley like this these want. . .:rofl:

http://www.ebay.co.uk/itm/CNC-6040-R...item2c5eac76e5

Sure, no problem if you make it for £805.
It's their way of getting Ebay fees down, you don't pay fees on shipping. One thing about this Portsmouth mob is that the machines are in country and you won't get hit by any import, handling or VAT.

To be honest you would be hard pressed to make one for this total amount even if you threw your labour in at zero

I live an hour from Portsmouth so have emailed them to see if i could pick up. see what that say.

Yes it does get the fees down, but you then get marked down on the DSR, and this will then effect your ability to sell on ebay.

Just as an exercise to satisfy my curiosity I set about working the cost of building this machine complete with VFD etc and think it could be made for around 1K. Thou that would be with no labour involved plus as usual there'll be something I've over looked.!!

THOU. . . Must say It be a far better, stronger machine because I've priced for profile on gantry and supported rails all round and better quality ballscrew supports FK/FF also the spindle would be 1.5KW.

Like I say Just an Exercise so don't anyone get excited I'm not offering. .:nope: If you have the time then it's just about do-able.! . . . . If you want Profit then forget it.

Absolutly no ulterior motive what so ever my friend, I'm strictly hobby use only with plenty of experience. To be honest most of what I do is make parts for other hobby users or help them with there builds/problems/info. Often I do this free of charge or for very little.

Yes I've built full machines small and large, very large in one case but to be honest this is my passion not my living and don't feel the need produce evidence to you or anyone. Basicly If they don't think I know what I'm talking about then don't ask me to help, either way I don't give a shit.!!

Regards trying to make a sale on the forum if you look again you'll see John S asked me not the other way round.! Also if you look even closer you'll find it was John's sweet way of having a little DIG at me to shut the f'%k-up. . . . BUT Me being ME and FIK as a plank it went way over my head.!!! . . . . . Plus I know the Old Bastard too well. (I'm not being offensive to John, anyone who knows him will see the funny side, including John)


The other thing I do lots of is help folks sort out poorly designed or so called "Professional built" machines and as such I see all kinds of build quality or lack of it in some case's.! . . . Your's I've yet to see but I'm sure I will sooner or later.!!

Can I suggest that instead of taking my comments as a personal attack with ulterior motive's you take them as critique thru exeperienced eyes and at very least look at what's been said.! . . . Hiding behind the "User request" hisn't good eneough IMO. It's your job to assist and if need be refuse to lower or comprimise the machines integrity by using inferior products or design.!!

After all this is a Public forum and while as usual I'm the first to open my BIG mouth on what negatives I see, I certainly wouldn't be the only one seeing this or thinking this and there would sooner or later be another saying it.? Probably the disgruntled users seeking advice but still would be said.
Again IMO it would be better to acknowledge and embrace critique then address any valid points and I do feel all the points I mentioned, mainly weak Z axis and Bed frame, after finding the full spec are perfectly valid given the price and the little extra cost to make right.!!. . . . . . Yes Maybe the comment about drill press and 2 days was a bit flippant.!! . . . It may take 3-4 days.!!!!!

Robin said it perfectly " The proof will be in the eating" so well see what cook thinks and I'll say no more other than Good luck and I wish you well in business. :tup:

Thanks for the comments
but we are not hiding behind the customers design brief & you agreed it was met ,we also have a range of upgrades available including spindles,gantry's, supported & hiwin rails as well as various other components but this is ultimately down to the customer & there budget if the upgrade or not we cannot give away free upgrades to assit in the customer receiving a better quality machine we are a business & this is not the way upgrades work or a business should be run & i think this is where the problem lies you are looking at this from your point of view as a hobby user & your quote for the small 6040 machine demonstrates this you quoted 1000.00 for parts alone not including labour costs this is 1/4 the size of the enclosed CNC & our CNC also has the 1850mmx1750x1800 enclosure & base , we have to factor in a whole lot more for our costs even so 4460.00 for a fully enclosed CNC router with a foot print of 1850x1750x1800 is extremely good this customer even admitted they have been looking for a machine for 6 months & could not even find anything near that size with there budget & they received a large base & enclosure with 4mm lexan for good measure we even put them in another set of double doors for free as well as free delivery at a cost of 290.00 all in all this customer received a bargain

RE the bed the customer confirmed to me last night the bed has no flex with just the base once the place there spoil board on the bed it will be 35mm

again Re the Z axis i have already said we offered the customer the supported rail upgrade but he only went for this on one axis if there budget will not allow the upgrade this in not our fault again this machine met the customers design spec & budget upgrades are not free im afraid from any company as the many user will know

it is very easy to discriminate & pic work by just looking at pictures of a unfinished machine but we would not post pictures of a half built machine they were sent to the customer as he wished to have a update on the progress of his machine , a customer should never see a uncompleted machine but this one was insistent as i guess he was excited
you were making judgements on a unfinished machine again it would be nice if i could see pictures of your several machines as you do give out allot of valid advice it would be nice to see some of your own work as you know you only learn from expirence so your machines should be pretty good
all the best

Going slightly off at a tangent the Heiz machines seem to have a following as they can provide from stock, no waiting, have a flashy web site and loads and loads of buzz words. Anyone with half an engineering brain can see the short comings thay have but they have a market.
Would I buy one ? no I'd sooner buy a Chinese one and make the necessary mods to it and still be quids in.

However this forum isn't really the place to bash other peoples work. There is a fine line between bashing and useful criticism.

I can see the OP going for the Strike machine and his reasoning behind it. He has a product to make which I presume he understands. His job is not to spend time making a machine when he has a product to produce. In this case it looks like he's worked with Strike and they have come up with the goods and given the changes, on time.

That in itself is commendable today, says John who has just opened yet another Paypal dispute, this time for 20 3" pipe fittings they can't supply even though they can take the money !!

You can't tell them to go forth and multiply so you have to apply the old maxim, "Don't feed the Trolls".

Hi Robin,

I won't get chance to do anything with the machine for another week or two. As soon as its up and cutting I'll post a video and details on here.

Ideally I'm looking at cutting at 2000mm/min with 5mm DOC with 8mm dia cutter in MDF. I'm building loudspeaker cabinets and not space shuttle parts so for real world tolerances on parts I'll be happy with anything better than +/-0.2mm.

Hey folks. After a spell of disappointments I've been wanting to update this thread with good news for awhile now

Its a long and probably not that interesting story but the original machine had issues with flex and play in the Z axis. With the help of JazzCNC(thanks mate) I found out the causes and took this information back to the manufacturer who did the right thing and agreed to rebuild the gantry. We stuck up a deal whereby they agreed to upgrade some of the gantry components because of inconvenience caused and I paid extra on top for them to use heavy gauge 200x40mm extrusion. You could argue that it should have been built like that from the start but I'm more interested in cutting now rather than questioning manufacturer build decisions. The important thing is its fixed and looking good for materials up to aluminium.

Jazz is sorting out some changes to the way the X axis ballscrews are mounted and I've still got a bunch of odd jobs to do here and there but I reckon it'll be cutting its first part within the next couple of weeks.

I've attached a few shots of the new gantry. Compare these to the original posted on page 4 of this thread. Looking in much better shape now.

I feel your pain But glad your machine has been returned and you are happy

did you get the controller box upgraded at the same time??

Looking forward to seeing the first set of speakers coming off your CNC Machine

Cheers James.

The electronics supplied with the machine were OK but I wanted to more speed. To help with this, Strike did give me a 60v regulated PSU as part of the compensation but I had a change of plans and went with a pair of unregulated 70v supplies for the four drivers. I've taken it upon myself to upgrade the electronics and have got a lot of enjoyment out of doing that.

Now there's a surprise. Lets hope StrikeCNC do better with future machines.

Well that's it. They did fix the issues and added a bunch of extra's on to the machine for the hassle. Building two gantrys surely wasn't much of an exercise in maximising profitability so I'm sure they'll learn from this and use it to avoid similar situations.

I don't really care about it now to be honest, once its up and cutting I doubt I'll remember at all.

Do you lot know how hard it was for a bloke with a BIG MOUTH to keep it shut.. .:yahoo:

I was going to say Strike CNC should be commended for putting it right but won't because it should have been right first time round but they did show the mark of a good company and did the right thing eventually.!! . . . Anyway I'm just happy for Ant that he's almost back on track and Hopefully he'll be making nasty MDF dust by the end of Wed.!! . . . .Well maybe friday he'll be punchng holes in the bed and crashing the limits for the first few days I'm sure. .:joker: . . (Not that I've done that EVER. .:whistling:)

Nice to see a happy boy:dance:Now go and build some gorgeous cabinets.

The company building mine has gone on strike. But i will be back to work soon.
