Industrial use diamond mounted point diamond grinding head Diamond SDC/Boron nitride (CBN) precision inner hole grinding rod Diamond SDC inner hole grinding rod, used with inner hole grinding machine, can be used for inner diameter grinding, such as ceramic, sapphire, glass and superhard alloy aperture fine grinding,Boron nitride (CBN) precision grinding rod is used for high-hardness carbon steel and chromium alloy steel fine grinding. Can make the inner hole after processing, higher precision. The alloy shaft diameter is used, so the rigidity is particularly strong, and the high-precision processing machine is most suitable. Main uses: Boron nitride (CBN) inner hole grinding wheel for a variety of tool steel, alloy steel (HRC50-70) hardness, bearing steel heat treatment steel parts inner hole grinding Support non-standard customization Please indicate SDC or CBN when ordering
