It's time to find a new home for this guy. I need to make room in the shop. It has served me very well for the past several years. I've made lots of very cool stuff on it, including steam engine related items. It can do the same for you.  

Work window is X-19, Y-7, Z-12. CNC range of Z axis is 5. Head tram is within 0.001 over six inches. X and Y axises can be disengaged and used manually. Z axis can be disengaged and used as a conventional drill press or for tapping.

I've upgraded the controller to the latest licensed version of Mach 3. The spindle has been upgraded with a three phase motor and a hitachi VFD which provides computer specified control of rpm in cnc program. Maximum rpm can range from 50-3200 depending upon belt configuration Spindle accepts R8 collets. There is the z-axis DRO for precise drilling and milling manually. I also made a chip guard and pan which contains about 95% of the chips. It was also intended for flood coolant, but never got the system hooked up.  

The controller uses a CNC4PC gs11 breakout board. It also uses proximity sensors for homing/limit switches. There is a space to mount a 4th axis stepper drive in the controller. There is also a 10 amp 110vac outlet configured to toggle with the coolant button in software.

Axises are driven by 3 1200oz steppers using Gecko g201 stepper drives.  

Machine can be put under powered for testing the demonstration purposes if desired.

This is perfect for a home shop that is looking to venture into the world of cnc machining. I will be more than happy to help set up the machine and show you how to use.

$5500 OBO.


Spline wrench
PC and monitor
Controller with full mach3 license
Coolant system related accessories
And perhaps other stuff I'm digging up right now

I do have a vise and r8 tooling available separately.

Unit is located in Santee, California, I do have means to transport the machine for additional fee. How much depends on how far you want to move it.
