X travel is 12 in. Y Travel is 16 in. I made a special extra-long Thompson ball screw for the Y axis. The Z axis travel is about 10.6 in.The motor mounts and ballscrews came from CNC Fusion. All motors are coupled with 0 backlash helical couplers.
I custom made the 4th axis out of a manual rotary table. The motor mount isnt beautiful, but it is fully functional.
Speaking of ugly but functional, the machine has a z axis counter balance that I made out of scrap. An ugly dumbbell hangs off the back of the machine, but it is perfectly weighted to balance the z axis load of spindle. The machine doesnt require it, but it make life easier for the z axis stepper.The machine is mounted to a 1 solid anodized aluminum table. I welded a 4 tubular steel support structure under the table and behind the column for super rigidity. The Z column of the machine is drilled and tapped about every 2 and bolted to the support column. The holes on the support column allow for tramming adjustment.
Thw under table support is bolted directly to the aluminum table top. I made hinged keyboard and mouse trays so they can fold down out of the way to save space and keep chips from getting stuck in the keys while cutting. I replaced the underpowered original motor with a 1.5hp treadmill motor and custom mount. The spindle speed is controlled via the computer. I 3d printed a custom shroud for the motor electronics so the built in fan keeps everything nice and cool.The machine has a new R8 spindle with belt drive instead of the terrible stock gears. It runs quietly and smoothly. The machine is controlled by a 4 axis Gecko Drive G540, which I built in to the included computer. The computer is currently running windows XP to avoid using unnecessary resources. It has Wifi so you can connect to the cloud to download your Gcode.
The computer will come with licensed Mach3 and a custom profile for the machine. All the settings have been precisely adjusted for this exact machine.The machine has an iMach III pendant for traditional manual movement. It makes it much easier to move the machine around. Axes are driven by 381oz in stepper motors.
I upgraded the gib screws with ball bearing screws for far better gib adjustment. I used the machine for prototyping before I got the new HAAS.
It maybe has 100 hours on it if that. I used it to cut aluminum. I could take a HSS 2 flute. 25 end mill about 12 in/min at 0.25 deep for roughing passes. It does circles around a regular Sieg X2.
The spindle has overload protection, so if you get too crazy it will shut down to prevent over heating. Tooling:The machine comes with the Tormach Tooling System for very quick repeatable tool changes. You simply stick a rod in the spindle lock, slightly loosen the drawbar, and lightly tap the drawbar. The tool holder will fall right out. The best part is the tool stays mounted in the tool holder, so you can measure the tools off the machine and dont need to re-measure when putting it back in after switching tools.

Mobile 1 vactra oil no. I bought my new machine before I got around to that. To use it as is you need to supply air to the quick coupler, and just plug in the dc barrel to the solenoid.There is already a manual lever if you just want to remove the solenoid. I also have a printer port power adapter should you want to use a laptop to run the machine at a later date. The adapter is required to supply power for the charge pump to the G540 from a laptop. Desktop pcs do this inherently and dont require it.
The machine is ready to go and can be demonstrated in person. You will need a truck or trailer to pick it up since the table and machine can be thought of as 1 piece. It is possible to take it apart and move everything by hand, but then you will need to align it all again. I have equipment to help load the machine. Machine weighs probably more than 500 lbs.
If you have any questions feel free to ask. I made the whole thing so I know everything there is to know about it. Machine is listed elsewhere so make offers fast before it is gone!
