This kit provides the mechanical elements you need to convert a bench mill with a 700 mm x 160 mm table to CNC. It includes ball screws, ball screw nuts, thrust bearings, and motor mounts plus the fasteners you need to install them. It does not include motors, drivers, power supply, or software. See the Documents tab for the electronics and software you will need in addition to this kit.
The ball screws are 16 mm diameter and 5 mm pitch, C7 grade with a tolerance of 30 microns over 300 mm.
All aluminum parts are clear anodized for corrosion and scratch resistance.
This kit is designed to be adjustable to any and all of the machines shown on the compatibility tab. Sometimes it just isn't possible. Because of manufacturing tolerances, there is variation from machine to machine. When installing the kit you may need to make some modifications not listed in the instructions.
Made by HEAVY METAL, these kits are the most solid, rigid kit you can find. They have been on the market since 2006. They have had very few revisions in all that time.
Your mill may need some modification for everything to fit correctly.
