Mini-Mill 3

​CNC Mini-Mill 3 The most affordable aircraft-grade aluminum frame, micro milling machining system on the market. We’ve sold hundreds of these machines in over 30 countries world wide.

The Minitech Mini-Mill 3 uses THK caged ball linear bearings, and high precision ball-screws for all stages. This is the same high-quality components that larger CNCs have.

Minitech uses only the best quality components.  Our products are manufactured with best-in-class materials, and assembled using the finest and most advanced techniques on the market. We are proud to put our stamp of approval on every one of our machines, and are sure that you will be satisfied with the results. 

The CNC Mini-Mill 3 is ideal for microfluidic, micro-electromechanical, Nanotechnology Industries, Jeweler, Research Laboratories and many others.

The CNC Mini-Mill 3 is available as a standard three axis machine with optional 4th Axis Rotary Stage, or 5 Axis Trunnion Table.

LM Guides with caged ball technology

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 incorporation of THK Caged Technology in this new LM Guide eliminates the need for frequent lubrication and results in long-term maintenance-free performance. The low particle generation of this design makes it ideal for precision equipment applications including medical, semiconductor equipment, and measuring instruments.
