Diamond Lapping and Lapping Plate Control

摘要

The word "diamond" brings the word "expensive" to mind. But when it comes to lapping with diamond superabrasives, start thinking "low" - as in lower slurry consumption, lower slurry cost per hour, lower sludge generation, lower cycle time, lower reject rates and fewer process steps. Diamond lapping might be appropriate for machining/finishing operations that face challenges such as greater planar, spherical or conical surface requirements; improved sealing; improved cosmetic surfaces; planarizing joined dissimilar materials (for example, laminates, composites); surface deburring, removal of "gummy" materials; super-hard materials that are only economically processed with the use of diamond; and thinning/finishing poor aspect ratio parts. Common industrial applications for diamond lapping include mechanical seals, seal rings, valves, stamping dies, pump bodies, slitter blades, gage blocks ("Jo-blocks"), micrometer spindles, fuel injection valves, dies/gaskets, CD molds, mirrors and micro electro-mechanical devices (MEMs). Almost any material can be lapped, including steel, stainless steel, chromium carbide, tungsten carbide, aluminum, copper, bronze, Alinco (aluminum-nickel-cobalt), ceramics, glass, sapphire and plastic.
