UPC-R is a circular cutting edge UPC ultra-precision diamond cutting tools, their typical use for DVD aspherical lens mold super finishing. UPC-R tool circular cutting edge contour accuracy of less than 50 nm, is the world's highest accuracy; arc R is only 5, is the world's smallest. Aspherical lens mold UPC-R ultra-fine diamond tools in ultra-precision machine tools and CNC coordinate processing processing highlights include: ① how to form a thin, stable chip continuous and smooth discharge Honing stone; ② workpiece rotation should be a high level of balancing performance ; ③ workpiece can be accurately centering; ④ cutting fluid and stable supply.
To the workpiece when machining steel thermo-chemical reaction causes the diamond graphitization diffusion, UPC diamond tool is not suitable for steel mold super finishing. If the surface of the steel mold with the non-electrolytic plating on the nickel plating layer of several tens of micrometers to several hundreds of microns thick, available UPC diamond tool for superfinishing. Should be selected on the coating quality, does not produce amorphous coating porosity, segregation crystal structure defects diamond cut wheels.
