M73 Series
Surface Grinding Machine
Features
The M73 series horizontal shaft rotary table grinders is the newly developed grinder which is made by our plant by absorbing modern grinders structure and technology of dometstic and overseas. The rotary tables diameter is 400mm to 1250mm. For the overall arrangement, the table rotates on the motive carriage. The carriage reciprocates longitudinally on the slideway of grinder bed. The grind head moves vertically along shaft. The surface of table can be adjusted + 3°for the prupose of middle concave and convex on the grinding surface. The rotary tables diameter is 1600mm to 2200mm. For the overall arrangement, the table rotates fixed on the slideway of grinder bed. The crossbeam is on the double vertical shaft. The carriage reciprocates longitudinally on the crossbeam. The grind head moves vertically along carriage.The grinder features in compact structure, reliable precision, excellent workmanship and convenient operation. The emery wheel is grinded on the periphery which the high parallel of the two surface of workpiece can be obtained. This grinder is widely used in precision making of circular part, valve plate, saw plate and milling cutter in the tool factory, bearing factory, air compressor factory and ordinary machinery plant.
