Of course it can be used for many other CNC machines.\u00a0 Taig has a somewhat unique issue against\u00a0running at high speeds. The 20 TPI screws provide excellent torque but require 2,000 rpm to achieve 100 IPM (Inches per Minute) travel.\u00a0 Most steppers max out about 1500 rpm and run most comfortably at 500-750 rpm.

It will lift the heavy Taig motor and spindle all day at that speed without stalling.<\/p>\n<p>I don\u2019t intend to do any machining at 100 IPM\u00a0as the bits I use won\u2019t take the force. It is an impressive \u201crapid\u201d speed when desired. However, I also have some concern about potential increased wear with constant operation\u00a0that speed.
