The Minitech CNC Mini-Mill/GX is an affordable precision-ground, granite frame, micro machining system.  The machine features LM Guides with caged ball technology and 60,000 RPM spindle. THK Caged Technology employs a synthetic resin cage with a patented curvature that cradles each ball and separates it from the next one. The spaces between the rolling elements retain grease and act as a lubrication system.  The natural granite construction offers excellent stability and strength along with a high degree of vibration dampening as well as thermal stability. The Mini-Mill/GX is available as a standard three axis machine with optional 4th Axis Rotary Stage, or 5 Axis Trunnion Table. ​Machines can be modified to meet your specific needs.
