1. Multi-specification cylindrical grinding wheel
The cylindrical grinding wheel adjusts the formula and size of the grinding wheel according to the different needs of the grinding workpiece. Among the vitrified bond cbn grinding wheels, cylindrical grinding wheels are often used in the grinding of automobile engine parts. Especially the fine grinding of camshafts and crankshafts. Grinding wheel specifications are also divided into single-piece, double-piece and combined multi-piece.
Grinding the crankshaft grinding wheel mainly grinds the thrust surface and other parts of the crankshaft. Because the materials for producing the crankshaft are mostly high-hardness and difficult-to-machine materials such as chilled cast iron, and the machining accuracy of the crankshaft is very high. Therefore, the general grinding wheel is difficult to meet the grinding requirements. At present, the commonly used grinding wheel for crankshaft grinding is vitrified bond cbn grinding wheel.
3. Ceramic cbn grinding wheel grinding crankshaft grinding wheel
The use of ceramic cbn grinding wheels for crankshaft grinding is because ceramic cbn grinding wheels have the following advantages:
◆ High grinding efficiency, high hardness of grinding wheel, high efficiency and wear resistance;
◆ Good thermal conductivity, low grinding temperature, not easy to cause workpiece burn;
◆ Ceramic cbn grinding wheel has good self-sharpening, sharp grinding, good shape retention of workpiece and high machining accuracy.
