Product Description
Honing is a kind of cutting method which is guided by the surface to be machined and the tool rotates and reciprocates. With high efficiency, roundness and cylindricity and surface roughness can be adjusted at any time according to needs, it is an ideal choice for high-precision machining of inner holes.
Diamond oil stone:suitable for precision machining of cast iron, aluminum alloy, copper alloy, ceramics, cemented carbide, magnetic materials, electric carbon products and non-ferrous metals.
Cubic boron nitride (CBN) oil stone:suitable for tool steel, die steel, alloy steel, stainless steel, quenched parts and surface chromium plating and other high hardness materials processing. Sunnen type Honing Stones specification chart:
