 Product Introduction

G75 Series Double Column Gantry Moving Rail Grinding Surface Grinder Product Introduction :

This series of machine tools adopts a gantry layout, and consists of a closed high-rigidity frame structure composed of double columns, beams and bed. It is a program-controlled (NC) fixed-beam gantry rail grinder integrating advanced technologies such as machinery, electricity, and hydraulics Grinding.

Product Features

Hydrostatic bearing has the advantages of high motion accuracy, no wear, long life, small starting power, high bearing capacity and good vibration resistance at high speed

Longitudinal moves hydraulically with variable speed

G75 series means the machine can be configured with the CNC system to expand to 2 axis CNC machine.

Application

The machine is mainly suitable for grinding steel parts, cast iron and various non-ferrous metal parts especially important surface, also can grind non-metallic sapphire and other materials, suitable for machinery processing plant, Grinding tool processing plant and Automobile and other industries of medium and large parts grinding.
