What 'decent' Milling machine?

Having previously designed and built a CNC machine, I learnt a lot about what works and what doesn't. I dont want to waste time trying to get a machine to work as needed, I managed to get semi decent results, the kit was decent, but not sure my design did it justice.

So looking at this again however keen to buy something that is ready built and works.

I have 2 main requirements, a bit different, hoping that there is a machine that can do both.

The first is cutting of 2 gears, in brass or plastic. I have previously milled these from the 'top down' but had issues getting 100% centre when the one gear was flipped over. I believe now the better way to do that is to make 2 parts and join them together. A lathe is probably better to make the 'blank' and then use something to cut the gear slot. I dont know if these gears are custom or not. I have measured them and cannot find a module number they comply too. Some pics should be attached.

The second need is bike parts using Aluminium. I need something that can automate the production of a number of pieces as far as possible. Parts will be things like rear sets, levers etc.

Ideally it should have a auto tool changer or one where I can simply remove the tool and apply the new tool without having to reset the Z all the time.

Ive looked at a number of machines from companies like Axminster, Amadeal etc.

No fixed budget, cheaper is better but willing to look at machines that are anything up to £10K. Doesnt need to be new, 2nd hand also welcome. My preference is something that connects via USB like the PlanetCNC card or similar.

Size wise, not massive, but I dont want to buy too small and be stuck. A milling area of 300mm x 300mm sounds reasonable.

Any suggestions?

Anyone?

Thanks in advance.

All the hobby CNC's you mention above are similar in quality and finish. It is the aftercare that you should learn about.

You are doing the right thing in budgeting for a turnkey machine if you are interested in producing bits professionally.

Get something with either an ISO 30 or R8 spindle. Some of the Syil machines come with pneumatic drawbars that save time and really make life that much better. Worth finding out which ones.

ATC's are useful but you can live without them.

Enclosures are VERY GOOD! I wish I could enclose my mill.

Many thanks for the response.

I noted that the Axminster ones, probably like many, are all Chinese made. Not always a bad thing.

What should I budget for something that can work to 0.01mm with at least a quick change bit system like the drawbars (I assume its the clamp thing, powered with compressed air)?

I'm also sure that for these gears, a lathe will be needed, I dont want to try and find a compromise machine but certainly something that can 'turn' a material and mill will be ideal. I could do blanks on a mill and then look at options for cutting the gear.

Any thoughts on this mill?

http://www.axminster.co.uk/axminster-sieg-kx1s-cnc-mill

http://www.axminster.co.uk/axminster...logy-ikx1-mill - at least it has a ATC of sorts.

If you are able to get a machine for less than £30K to work at 0,01mm please let me know. It really cannot be done at this level of investment. You can get close to 0.01mm but if you are lucky and the moons align you may hit it one day. I would be content with 0.05mm on any milling job even professionally done. Thermal expansions and other sources of error will conspire against you.

May I suggest you go to the various shops and have a look at the machines? They are all much of a muchness in terms of quality and build. Its the extras that really make it.

Ok, understood. Was being pushy in terms of 'spec'. 0.05 is acceptable for what I need, probably 0.1 too but thats max.

I want to go to Axminster in High Wycombe however still waiting for their technical sales team to get back to me and from what I can see on the shop pics, they dont actually seem to keep these in stock for viewing. Might be wrong, but lets see.

Since you are in the area see Amadeal too.

Why is this so expensive?

http://www.ebay.co.uk/itm/Ballscrew-...71985621&rt=nc

Ive dealt with this company before, used to buy parts for our 3D printers. The item has 25 watchers ..... I fail to see where £10K is here. The spindle is a £150 Kress .... am I missing something?

It's just a little trick we sellers on ebay do when an item is out of stock or short term unavailable, set the price mighty high and no one will buy it hopefully adding the item to their watch list ready for when the price is adjusted to something reasonable again.

If you just close the listing down - as a seller, you lose the intrest, watchers and so on that the item listing has attracted, this is only ideal really when you have a multiple quantity listing going where you have sold lots of the same item already and as such don't want to lose all that good work (a listing is placed higher on the search results page when it has sold well previously, positive feedback recived and so on).

Ah, ok, makes sense. They have a number of machines at £7K, dont see the value.

Anyways - thoughts on this machine:-

http://www.ebay.co.uk/itm/NEW-Syil-X...09184487&rt=nc

or the slightly cheaper non enclosed version:-

http://www.ebay.co.uk/itm/Syil-X5plu...99403162&rt=nc

Syil X5 basically.

Ok, two Denford machines, look like 'old' quality. Both Mach3 converted.

Thoughts? Only thing Id like is probably a 4th axis. Assume that could be fit later?

http://www.ebay.co.uk/itm/Denford-Tr...item2a4ffc8891

http://www.ebay.co.uk/itm/Denford-Tr...30576529&rt=nc

Denfords are excellent IMHO.

The machines at Amadeal with spindle taper R8, big No for that money.

If i want to buy me a serious mill i will look for used VMC, at least buy Bridgeport and definitely stay away from small mills with funny tapers and unknown Chinese stuff.

You need at least BT30, ideally 40iso holder for a serious machine.

Thanks. I did see a few bridgeports. What do you think of the 2 Denfords I linked?

Worth a punt?

On these older machines, how do you get the gcode onto their 'PC' / Controller?

Cleaner version of the same thing. Looks a decent sturdy machine.

Depends. Small machines are way overpriced compared to used "real" machine. Cause people are lazy to organize moving or installing 3 phase at home, or fiddli8ng with VFD or just make small parts and don't have space.

I still don't have a mill but from looking of what motorcycle parts people order to my friend Jeff, i dont see that machine capable of doing them. Fork yokes for example. As i said stay away from small machines.
Man, my mill vice is as big as this machine if you know what i mean. You can not fit a good vice, the part and the bit on something so small. Not to speak of tilting vice.

You need a good used machine that comes with some stuff like holders, vice/es/ and if you are listening to me- that comes with servos. Yes its a good thing to retrofit steppers, no problems, but machine that comes with steppers is an amateur machine.

Cause you will hit the floor when you hear the prices of a good vice, good 4rth axis and so on if you want to buy them separately. And if you manage to find a good machine and retrofit only the electronics / something like CSMIO/ IP A / you could have a look at https://www.youtube.com/watch?v=TlQgMk6te_Y so you spend wisely you 10k

Silyavski bet me too it and i was going to say same.

You can find Old machines like that Bridgeport that just need new life breathing into them.
You don't waste your time trying to use there old standard controllers just rip them out and retrofit with modern one. Often there control on these things are limited with very little memory.
You'll find on older machines the drives will require 0-10v analog signals rather than step & dir like modern stuff uses.
Ounce upon a time this made life difficult for your average person to retrofit or Very very expensive after market controllers so often things like drives and motors where replaced making it expensive and uneconomical in some cases.!! . . But not anymore now Cslabs have a analog Controller at sensible enough money that was designed just this purpose of retro fittng old machines. Even ones that use 12 or 24 logic.!

This means often all you need to replace is the Controller and with a bit of re-wiring you can re-use all the existing components and get the machine working like it's never done before.!
Just be aware thou most industrial spec machines require 3 phase power.! Often this is just for the Spindle not the Motors or drives. On many old machines like that Bridge port you'll find either Steppers or Brushed DC servos. Depending on drives etc often it just means changing or rewiring a transfomer so use single phase.
The Spindle is the main thing that will require 3 phase but often you can just run these straight from a VFD. Or you can buy Converter that will transform single phase to three phase if large HP.

Personally I'd wait for some Old iron to come along and replace everything with moderern servos and controller etc before buy those mickey mouse toys.

Here's a prime Example of what £600 buys you in Old money.!! . . . . Purpose built CNC not converted Mill with 1000x500x450 travel. DC Servos, 7.5HP 40 taper spindle with power drawbar, Ground ballscrews and linear ways.

All this machine needed to get working was the controller replacing and 3 phase power. It uses Brushed DC servos which I will be replacing with modern Servos and the Spindle will be run from a Converter.
But the point is that if you had 3 phase power another £600 would have had this machine fully working and running like it never did before on it's old controller.
There are old machines like this coming up all the time at very low money and if you throw 2-3K at them you will have a very very good strong accurate machine will all modern components.

Not same thing at all. Same Manufacturer very differant animal. The first is much strong model IMO.

Chances are both these models use Steppers not servo's. If they do use servos they most likely will be Brushed DC servos and use 0-10v with maybe custom drives so do some research before buying if paying big money.
If controller is working then check out it's spec, memory etc and how it accepts G-code etc. If your planning on doing 3D work then often the controller is the weak link so paying for a machine with a working control is wasted money as you'll most likely rip it out.!!

Get bidding.!!!!

Thanks to both. So basically look at something like the Bridgeport? I dont mind doing some retrofitting. I used the PlanetCNC USB controller before and loved it.

Thoughts on the Denfords, are they considered 'toys' or more like the real deal?

Forget PlanetCNC for retro fitting again it's a toy. You wan't ethernet for serious machine USB is rubbish and unreliable IMO.

Denfords are still toys but very good toys.!! . . . . . . By the way the Denford in Dewsbury you show I know the guy who Converted that to Mach3. He actually works for the Company who's selling it.

If your planning on milling aluminium then look towards a machine with high spindle speeds 5K is minimum 10K + better.

Thanks again all. Problem is no 3 phase at home. I could run a VFD for the spindle. Cant help but get the feeling Im biting off more than I can chew :-(

Mmmmm. I dont know enough about whats good and what bits are good and the potential money pit is big I think, especially if I need to start to retrofit parts.

They have the same name and model from what I can tell. What is different between them? Trying to learn from what you are spotting as to what is important and what is not.

It's not difficult but does require some knowledge and plenty of research before commiting.

IMO all the machines you have shown so far are cheap (with exception of Denford) chinese imports. They are badged up with someone elses name on but all the same low quality machines.
I think you will be disspointed with the results and you will in the end up either chasing away problems they have and wasting money doing so or selling on.! . . . All cases you'll still Blow money.!!

Old machine and retro fit will serve you better in long run. Also You'll more than likely sell it for more than you payed if you ever do move on or upgrade.

To be honest for your needs with aluminium and plastics which requires higher spindle rpm/feeds I'd build a very strong Fixed Gantry machine and put the money into using good components and ATC spindle before waste on those Chinese Import Milling machines.
The mills will always perform below par for cutting aluminium and plastics compared to strong machine built and spec'd for the task.

Retro fitting a old machine with a high RPM spindle 8k plus would be only choice between building or buying. No way would I consider Small mill for cutting aluminium unless it had high rpm spindle and used Linear bearings.!!

Thanks. I did build my own machine before. It worked 'OK' but not sure Ill do that again. Here is a vid of it cutting a plastic gear with a 1mm high speed endmill.

https://www.youtube.com/watch?v=t_jXTrO0rok

I could not get the rigidity I needed and making centre holes (on a different gear) proved almost impossible.

Well what do you expect if you built it out of spagetti.!! . . . . . I'm talking about properly built machine built with substantial materials and correctly done.
If done properly then it's not difficult to build a machine that will do everything you need and do it much better than any cheap chinese import mill can.!

The difference between th 2 bridgeports is the series. MK1 & Mk2 They look like this.

Ye, understood and lesson learnt with schoolfees to match.

Can you link to something that you refer to as a suitable DIY type machine please? Appreciate your time with the feedback / comments.

Going to be honest now and you may not like it.!!

It appears to me that you don't have enough machining experience yet to justify laying out big money on machines when you don't even know what you require.
For instance the best mill or CNC machine won't make relocating your part any more accurate if you don't know how to do it.!

The fact the machine you built doesn't make the grade is purely down to poor weak design and choice of materials. The fact you can't relocate on centre is down to your low level of experience.
If you'd made fixture jigs to hold your work and indexed to a known fixed reference point then it's easy.

But your machine is so weak it will flex like jelly so this can't happen. Trying to re-locate centres without a fixture is hard at best of time on any machine and requires accurate devices to help. So no matter weak or Strong if you haven't got the abilty or the equipment then you will always struggle.

Your weak build is to blame for low part accurecy for sure but has nothing to do with reloctating and no amount of strength in the machine will helps this as it's down to you to come up with ways to fixture.

Properly built DIY machine which uses good components will easily do what you want.

Ah, a bit harsh, but that OK.

I dont know what I need, hence the thread to ask for advice.

The relocation of the centre was badly explained. I dont think the machine had the rigidity to be accurate enough and the centre was the easiest place to spot this. But agreed, I have a lot to learn and yes, I dont know the techniques.

So I consider myself 'told off', no problems there. At least I tried based on what I could do on my own.

Are you able to link to something that you would consider suitable on the DIY side?

Out of interest, what would a machine like this cost in the UK?

There are several Fixed gantry machines on the Forum search for those.
To get the strength you require then fixed gantry is the way to go and built from steel if possible. Moving gantry machines can do it but they need to be very very strong.

Erm well sorry but better being said than just thought and seeing you taking wrong route.!

When ever you have to flip parts and require more than 2 it's worth taking the time to make a fixture Jig. Provided the Jig is well made and indexed to a fixed known location you will always get back to absolute accurate position. If the machine is made from jelly then you'll still be back in absolutle position you started it's just the machine doesn't go there if it's wobblying about.!!

Something like this?

Found the vid of it milling alu, then found the thread.

Not trying to sell you or anyone anything here but may be would be of interest to you. If time is not an issue, cause i am a bit busy right now.

I am currently designing a couple of small CNCs cause i want to start small home production of quality machines. All will be made entirely of 20mm aluminum plate. All 200mm Z axis.

So i have semi finished 3 designs of small machines. I don't want to load you with information now, just the thing is that maybe i will start making first the 600x400x200 moving gantry prototype. As i have semi finished drawing of the fixed gantry machine if you are interested i could provide you the drawing, only condition will be to use what elements i tell you, so you act like a test pilot :hysterical:

The said machine will easily handle 3kw spindle or even much more.

400x400x200mm, the bearing design and rails spacing is already tested on my previous build 1, the yellow machine, so no risks here. Parts will be around 3000$$ so you only have to put all together.

Apart from being light years better from anything i know of for the same $$ it would be extremely strong and beautiful, remember, all parts 20mm aluminum including the tool table.

Even the moving gantry machine will easily do the same plus its even more versatile. The yellow machine using mere 0.8kw spindle handles with fully extended Z aluminum with perfect finish with 1.5mm depth of cut, 800mm/min 12000RPM

And remember i am talking about OTT machines capable of working 24/7, not toys.


About the Tormach, i dont believe it could hold 0.05mm precision from what i have read around.

Well it's nicely made but could be stronger. The Vid cutting aluminium is more like scratching than cutting. I've built Moving gantry routers designed just for wood that cut aluminium deeper than he is doing.
With a Fixed gantry machine and decent spindle it will do a much better job of munching Ali.!!

For what it is, its OK. Ask somebody on machinist forum and they will say its a crap and you need HAAS mini mill:joker:


About the one on the video. Has some small important details overlooked and some weak links , that bothers me..., not up to my standard. of design i mean.

at the left is the fixed gantry, still not finished.




This is the one i intend to prototype first. I was going to hide it until ready and physically finished, but as sooner or later has to pass the "Dean test" , better now:loyal: than later
I will be starting to buy parts for it next week. It will be solid aluminum beast.
