CG460-575-600-650 CRANKSHAFTS AND UNIVERSAL GRINDING MACHINES BASE AND TABLE The base is made of high resistance monolithic cast iron, thermically stabilized, it has one flat and one “V” guide. The table is a strong structure, thermically stabilized with scraped surface in order to secure the highest precision of linearity and flatness in the different positions of the workheads. The guideways are covered with special anti-friction plastic material in order to: • • • reduce the disengaging friction reduce the coefficient of general friction reduce the rubbing wear table movement with synchronous...

GRINDING WHEEL HEAD It moves on wide prismatic guideways. The grinding wheel spindle rotates by means of a wheelhead spindle with high precision pre-loaded bearings. The transmission of the motion to the spindle takes places by high power V belt. X and Z axis movement is made by hydraulic piston and it moves on wide prismatic guide ways. SET-UP AND CLAMPING SYSTEM The centring of the crankshaft is obtained by means of a special support equipped with three movements that allow solving precisely and easily any problem regarding the work-piece centring: • • • One offset movement on guides One side...
