Ultra Precision Grinding Machine UPG240

The UPG Series is another outstanding product from Mikrotools. It is capable of producing nano-finishing surfaces. The UPG-2520 uses the in-process dressing grinding system. This special grinding process uses ultra-fine diamond particles to produce mirror surface finishes on both metals and non-metals.
