Main Applications and Structural Features
· The grinding machine series, for production in batch,is suitable for grinding outer and inner cylinders, outer and inner cones, as well as axial end faces. It has features of high accuracy, good rigidity, high grinding efficiency,easy operation, etc.
· Φ320 Series grinding machines have been developed into diversified series products on the principle of modular design.
· Use of enlarged spindles and bearings of grinding wheels, greater motor power, up to Φ500mm gtinding wheels improve grinding efficency.
· Grinding wheel head with automatic cyclic feed provides four selecting modes:left feed, right feed, double feed and no feed.
· Arbitary angular adjustments of headstock within anticlockwise 90°and grinding wheel head within ±30°permit the machines to grind bigger outer and inner-cylindrical workpieces.
· Turning down the internal grinding carriae on the guard cover of grinding wheel head allows inner-cylindrical workpieces to be ground. 6 Sets of inner grinding rods are available for selective use.
· Electrical and hydraulic interlocks make all the moving parts offer safe and reliable movement.
