First run of DIY CNC

This machine is a small PCB sized milling and drilling machine. The spindle is custom built and uses a scaled down version of an R8 collet. It will be an automatic tool changing spindle once I get the tool rack made. The spindle runs at 24,000 RPM. Rapids of the machine are only 600 IPM at this time as I only have a 35 volt power supply for the steppers.

General specs are:
Accepts 1/8" shank tools
24,000 RPM spindle
20 tool capactity
Auto tool length measuring
9.5" X travel
15.5" Y travel
3.5" Z travel
600 IPM rapid rates
.0005" resolution (Min. increment)
Currently running on MACH3 software

hey where did you get the spindle from?

@565Customz

The spindle on this machine was made by me - it is a DIY spindle

What is the technical term for those wire guides, and where did you get them?

[RIAMCNC]

They are called Energy Chains, check on ebay as sometimes you can get a good deal

What's the setup for the x-axis. I think I see two linear ways above each other?

Do you use a ballscrew?

[RIAMCNC]

The X axis (axis on the bridge) used linear rails (IKO). The other two axes use bishop wisecarver rails. The Z axis uses a ball screw and the X and Y axis use a belt drive.

Nice

[DanFrederiksen]

nice speed, cool sounds : )

is it just a parallel port stepper that requires a realtime os?

[Mega666Mike]

Nice!

[razblack]

that's pretty incredible resolution... seems professionaly constructed.. how did you come up with the plan, what was total BOM, and do you have more samples of it working?

[pageygeeza]

I love the noise of the stepper motors!

[karandex]

ONLY 600 IPM ?????

great video great machine

[diyengineer]

This is a super cool mini machine!! Super fast!!

[cidadaovagamundo2]

Really nice CNC. What motors did you use?

@RIAMCNC nice! ive been trying to figure out how to build a 20ish thousand rpm spindle, but i want to use air bearings...and im not having much luck
