SDC grinding wheel (diamond) is an ideal grinding wheel for metal materials that are sensitive to grinding temperature, such as quenched steel, high vanadium high-speed steel, and aluminum high-speed steel, as it does not exhibit chip sticking during grinding and cutting of iron materials.
1. Different heat resistance:
CBN grinding wheel (cubic Boron nitride) can withstand the high temperature of 1250-1350 ℃.
SDC grinding wheel (diamond) has a heat resistance of up to 800 degrees Celsius.
2. Different uses:
CBN grinding wheel is mainly used to process hard and tough materials, especially Ferrous, such as various steel parts, cast iron, etc., workpieces: automobile parts crankshaft, camshaft, hydraulic parts, compressor parts, etc.
SDC grinding wheels are mainly used for processing hard and brittle materials, such as hard alloys, ceramics, glass, and other workpieces.
3. Different costs:
In terms of production cost, the price of CBN grinding wheel is much higher than that of SDC grinding wheel. If the machining of the workpiece allows, diamond grinding wheel is superior to CBN grinding wheel.
In summary, CBN grinding wheels and SDC grinding wheels are both superhard grinding wheels, and their applicability complements each other. Their abrasive toughness, hardness, and durability are tens or hundreds of times higher than those of corundum grinding wheels.
The actual selection still needs to be considered based on equipment, workpiece, processing method, operation, and actual needs!
