CNC Router V1.0 (For Cutting Multiple Materials)

[JoeHarris]

I'm getting very close to finishing....watch this space!

Any news?!

[biketrialsdave]

Oh so close! I have movement, all sensors working with mach 3 etc. Just need a spindle and I should be there. Got some slight crunching noise to sort out on one of the ballscrews. Only happens near the end of travel so I suspect it's an alignment issue?

Looking good! And very close to a finished machine. Nice one!

First cuts on a piece of old plywood!

https://youtu.be/rnGz0vA8aEIIts always nice to see a new machine doing its first cuts. Sounds nice as well.

Lovely looking machine Dave well done mate.

One question why is the spindle so high up the front plate.?

One suggestion.!! . . .Cut deeper.
That cut could have been done in one pass and much quicker. Know there your first cuts and probably think it's better or safer cutting shallow but your more likely to knacker the tool and snap it cutting shallow due it over heating the tool.

Very nice, looks a sturdy little machine there.

The spindle could really do with being lower, I agree. I wish I designed in more Z clearance height though! (Let that be a lesson to anyone designing a machine at the moment).

Your right about me being conservative. I'm now on a steep learning curve with feeds and speeds, in fact CAM in general. I was a bit naive thinking CAM would be the easy bit! :welcoming: Thanks for all the help yourself and the rest of the forum have given me; I feel this is only the beginning!...

Has anyone used one of these two piece vices before? Only 75mm total height which would help me.

Can't help with the vise but CAM is certainly the hardest part of the process ;)

I spend most of my non-machine time at the CAM stage, figuring out out how to do stuff and not break the machine or the tool. Dodging clamps is my current lesson;)

We use them, and they work well.

Long time since I've posted! Currently setting up to cut aluminium, just built a fogbuster clone...

Aluminium??!! Looks more like soggy cardboard to me 😉

I have a chinese mister 19664, which cost about a fiver and I have a project to use an arduino to control a peristaltic pump (which I 3D printed a short while ago) and an air solenoid valve. I intend to see what separate bursts of air and fluid is like for clearing chips and then dispensing coolant. I have all I need for the experiment, except my health has taken a downturn for the time being, but I want to get some progress on it.

Cheers,

Rob

Sounds interesting, I'll have to Google "peristaltic" first though :)

Sorry to hear about your health problems, hope you feel better soon, annoying isn't it when you've got toys to play with but can't really get to...

[cropwell]

Sounds interesting, I'll have to Google "peristaltic" first though :)19665 This is the pump, it basically massages the fluid though a soft tube, like the muscle action in our guts that keeps 'everything' moving. With a stepper to drive it, you can get very precise doses at high (ish) pressure.

[Robin Hewitt]

I used a peristaltic pump once to blow the paraffin electrolyte through a spark erosion tool.
Now, who would believe that you cannot get silicone rubber tubing that is paraffin proof?
Check your coolant! It is weird-a-mundo :(

[biketrialsdave]

Thanks for all the comments, I'll post more info/video soon.

On a different subject, does anyone use a face mill with their 2.2kw chinese spindle or am I best using an end mill?

[Davek0974]

i tried a 12mm single bit indexed tool on mine and it worked but i don't think any bigger will go, just not enough torque/power at lower speeds and you don't want a big mill whipping round at 24k ;)

Endmill - the face mill wont be balanced well enough for the speed that spindle does and as has been pointed out, 1Nm is not enough torque to cut much with it anyway.

So I finally got round to making a BOB. Hoping this will kick start me back onto doing more CNC stuff!!

WOW! :D
Please tell us more about the BOB?
Looks extremely good! Thinking about selling some?

BTW really nice machine too.
