Roll Camber / Cylindrical Grinder GRC 55

Versatile grinder for micro precision grinding of rolls with concave or convex cambering and heavy duty cylindrical grinding applications in general engineering industries.
Salient Features :
» Single piece robust construction with long guided sleeve for better rigidity of tailstock. Bed made of high tensile strength cast iron, heavily ribbed for better vibration damping and shock absorption.
» Dual table arrangement for taper setting and taper grinding facility.
» Antifriction roller guideways for infeed slide, ensuring micronic response and repeatability.
» Automatic infeed at table for traverse grinding operations.
» Plunge grinding cycle.
» Bearing pads of hydrodynamic super precision bearings are supported on cylindrical surfaces that adjust themselves automatically according to load changes during operations and ensure minimum clearance.
Special Executions :
» Machine with 2-Axes CNC control.
» Dynamic wheel balancing (HMT IZV-20 or MARPOSS).
» Inprocess gauging system.
» Hydraulic actuation of tailstock.
» Angular head grinding machines with single axis CNC control.
