CNC Router V1.0 (For Cutting Multiple Materials)

[Lee Roberts]

I have a chinese mister , 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...

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.

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 :(

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?

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!!
