253HT

Compact and versatile friendly use and tooling sectioning machine, planned to optimally cut metallographic samples, carbide, hardened steel, composites, plastic materials and so on…The specimen, once cut, is free of burrs and burns, going through any quality tests processes. 

The main feature of the 253HT is that it works on 3 axes (vertical, longitudinal, transversal table), furthermore the vertical movement grinding-wheel arm is assembled on linear guides and allows a high rigidity and precision during the cut. The 253HT is available in : manual, semi-automatic or fully automatic version, according to the customer cutting needs. Axes and cut-off wheel motions - motors, and all electric and electronic components - are assembled externally from the cutting area.
