Speedfam [india] is an internationally acclaimed leading group in flat machining technology offers double side-lapping machine for simultaneous lapping. The company manufactures these lapping and polishing machines in an advanced version of 4-way double side to serve critical needs. The unique 4-way motion principal of lapping and polishing machine helps to achieve accuracy in flatness, parallelism, thickness control and surface finish. The company supplies these lapping and polishing machine with upper and lower lapping plate rotating in opposite direction to each other. The component to be lapped is placed in the geared and driven carriers in planetary motion between upper and lower lapping plates due to outer and inner gear which rotates in same direction of lower plate creating 4-way motion. The double side lapping and polishing machine produce 0.3 microns or less flatness, 2 microns parallelism and 0.02 ra surface finish. The machine can process parts with 0.07 mm to 25 mm thickness. The double sided lapping and polishing machines are available with salient features like auto lap plates flatness control, high precision pneumatic pressure control system, brittle and fragile parts can be easily processed, variable speed control with soft start and stop for lap plates and optional thickness control system. The company supplies lapping and polishing machines in models based on size/capacity. These double sided lapping and polishing machines are applicable in computer valve plates, piston rings, watch glass, pump parts, shims, vanes washers, slips, quartz crystals, semi conductor waters and others.
