Picture

​The Minitech CNC Mini-Mill/GX is the most affordable precision-ground, granite frame, micro machining system on the market.

Minitech builds these machines using THK caged-ball linear bearings and high precision ball-screws for all stages. Each base is precision ground, polished and aligned to the micron level.

The Natural Granite construction offers excellent stability and strength along with a high degree of vibration dampening and thermal stability benefits not found in any other material. The GX is ideal for Microfluidic, Micro-electromechanical, Nanotechnology Industries, Jeweler, Research Laboratories and many others.

Hundreds sold in over 30 countries worldwide. Available 3, 4 and 5 axis
