Precision Matthews PM-25 Bolt-On Conversion Kit – No Machining Required – $785

(plus freight) While the Grizzly G0704 may still be considered a benchtop mill (it does come with its own stand) it is very different from the Sieg style machines. First of all, it has more travel. It’s a much heavier machine, and, most importantly, it has tapered gibs in its way system which are more accurate and need much less adjustments. Also, the G0704 has a 1hp motor which is leaps and bounds better than the smaller X2 machines The difference between the Sieg X2 style machines is there is some machining required to the table and Y axis base to convert it to CNC. Additional clearance is required to fit the ball screws and nuts to the machine.  If you have access to a larger machine or to a local machine shop, then you can follow the detailed instructions included in the kit. The conversion kit includes: (3) NEMA 23 stepper motor mounts (3) All new ball screws and nuts custom machined (3) All new shaft connectors All new thrust and tapered roller bearings All the necessary hardware to assemble to your machine
