Product Description

Equipment Overview

Equipment Name:Double-Station Cropper

Equipment Model:MTM370/2C

The MTM370/2 double-station cropper is a cutting equipment specially developed by our company and applied to cutting equipment with diameters ranging from 8 inches to 12 inches. It can achieve simultaneous cutting of both ends of the head and tail of a single raw bar and simultaneous removal of pieces. It has the features of convenience, speed, and high cutting efficiency. It can achieve the best cutting effect by using our independently developed diamond ring wire for cutting.

This machine is used for cutting semiconductor grade monocrystalline silicon. Processing bar size range: diameter from 8 inches to 12 inches, with a maximum length of 2200mm for the hair bar. High cutting efficiency and smooth cutting surface.
