 Nothing Compares to the GX by Minitech


Minitech GX 5 framed

The Natural Granite construction offers excellent stability and strength. a high degree of vibration dampening as well as thermal stability benefits not found in any other material.

The GX is ideal for the Microfluidic / Nano Industries, the Demanding Jeweler, High Tech Medical Products, Research Laboratories and more.

Each base is precision ground, polished and aligned to the micron level.

The GX is available standard as a three axis machine with optional fourth and fifth Axis.

Machines can be modified to meet your special needs on request.
