Beizhong manufacturer's lapping plates and cast iron lapping plates are used for inspecting the flatness of various precision parts (using the light gap method), and for repairing various gauge blocks, tool and inspection fixtures, optical components, and measuring the flatness of precision tools and parts.
Lapping plates and cast iron lapping plates are used for inspecting the flatness of various precision parts (using the light gap method), and for repairing various gauge blocks, tool and inspection fixtures, optical components, and measuring the flatness of precision tools and parts. Lapping plates are manufactured according to the JB/T7974-99 standard, with the working surface processed using grinding techniques for part grinding and gauge repair. The surface roughness of parts ground with this product is Ra ≤ 0.08 μm.
As the only measuring tool for repairing gauge blocks, the quality of cast iron lapping plates directly affects the repair quality of gauge blocks. Common materials for lapping plates include high phosphorus, alloy, and nodular cast iron. Gauge block repair requires one or even several lapping plates with effective lapping performance. Effective lapping performance refers to: 1. Good abrasive embedding—the plate easily embeds abrasives, and the embedded abrasives are firm and durable. 2. Simple and easy-to-operate lapping process. 3. Sharp cutting and wear resistance. 4. Easy achievement of the required surface roughness during gauge block repair. Gauge block repair must be completed within seconds or tens of seconds to meet technical indicators such as flatness, surface roughness, and changes in center length. The quality of the lapping plate used for gauge block repair directly affects the repair quality and efficiency of gauge blocks, making the lapping performance of the plate particularly important. Lapping plate specifications: 100*100mm, 200*100mm, 200*200mm, 300*300mm, 400*300mm, 400*400mm, 450*400mm, 500*300mm, 500*400mm, 600*450mm, 600*500mm, 600*300mm
