During the grinding process of bearing parts, the instantaneous grinding heat generated in the grinding zone can cause the temperature to rise suddenly, even more than 10,000. This instantaneous high temperature causes various thermal damages on the surface of the workpiece, which is grinding burns, and even more so, it can cause grinding cracks. Microscopic analysis shows that instantaneous high temperature will cause high-temperature tempering phase transformation on the surface of parts, or even secondary flame phase transformation, which will cause a series of surface characteristics such as wear resistance, corrosion resistance and fatigue strength of parts to deteriorate, resulting in bearing Early damage and early failure of parts must be avoided.
Generally, the main factors that affect grinding burns include workpiece material characteristics, grinding wheel characteristics and grinding process parameters (grinding wheel speed, workpiece speed, grinding depth, etc.)
In this paper, the grinding burn type and morphological characteristics of W180r4V steel bearing parts and the pickling inspection process showing grinding burns are tested.
Grinding burn types and morphological characteristics Grinding burns are caused by changes in the surface microstructure caused by the instantaneous high temperature generated in the grinding zone during the grinding process. Usually the peak temperature of the grinding surface determines the severity of the burn, that is, different types of grinding burns are produced.
1. The normal heat treatment process for high temperature tempering burn W18Cr4V bearing parts is 980°0 quenching and 50°C 0 tempering three times. When the instantaneous high temperature of the surface of the bearing part in the grinding process is higher than the normal tempering temperature of W80r4V, the local surface structure of the part will change, and the alloy carbides in the tempered martensite will further precipitate and accumulate. Such changes on the surface of the parts are called high temperature temper burns. The pickled surface is white-gray, as shown by the arrow A of the jacket raceway in Figure 1E28Ny/01. Due to the change of the surface layer structure, the hardness of the surface layer decreases. It can be seen from the microstructure and microhardness indentation of the cross section at the raceway burn of Fig. 2E26Ny/01 (shown in Fig. 1). The hardness of the tempered burn layer has decreased significantly. The microhardness of the normal area is IS0
(Load 200g), and the lowest value of the burn layer is only 2356.
