of the grinding force, the grinding efficiency is low
The ceramic materials grinding tangential the grinding force Fc radial grinding force Fp ratio Fc / Fp <0.1. Than grinding steel the small Xin (Fc / Fp = 0.3-0.5). I.e. radial grinding force Fp effect, and thus the force in the grinding wheel axis, so that the elastic deformation of the grinding wheel axis to increase, and prone to vibration affecting the machined surface quality. To this end, it is often to reduce the grinding wheel china, and cause the decrease of grinding efficiency.
after grinding will cause a reduction in strength of the ceramic parts
Little decrease in intensity of the General metal parts after grinding. While the strength of the parts after the grinding of ceramic materials with different grinding conditions. If the particle size of the abrasive, the time and part of the load conditions of the working environment and so influential.
① diamond grinding grain, grinding workpiece surface roughness also changes the flexural strength of the part. Si3N4, SiC, AlN, and ceramic parts such as the surface roughness values ??of approximately 1 micron, the strength of the parts will be reduced, the greater the surface roughness value, the bending strength is lower.
② the time of the load acting on the ceramic parts longer, the smaller the breaking stress of the ceramic parts, the lower the intensity. Usually ceramic parts of the workpiece very long time, and is the work, therefore, the actual intensity of the ceramic parts is lower than expected in a high temperature gas.
Diamond grinding wheel has what sense?
Diamond grinding wheel with what significance? Often used in our lives for a material such as diamond wheel, grinding wheel, however, whether it has particular relevance for what? First diamond wheel is used to undertake the abrasive layer, diamond grinding wheel and when used with the flange firmly clamped grinder spindle. The general metal bond products be of steel, alloy steel powder as matrix; the resin binder selection of aluminum alloy, electric wood substrate. By the processing of aluminum, steel, or Bakelite, and play a role of supporting the working layer and the loaded card abrasive. The the metal cutting wheel molding quality is good or bad and use level of accuracy are greatly matrix. More importantly, point diamond wheel not only high efficiency, high accuracy, and Roughness good, less abrasive consumption, long service life, and also to improve the working conditions. Therefore widely used in ordinary abrasive difficult to process low iron content of the metal and non-metal hard and brittle materials, such as cemented carbide, alumina ceramic, optical glass, agate gemstone, semiconductor materials, stone diamond wheel also has a lot of significance, may also be from other more angles to be understood.
