Ceramic microcrystal fused alumina grinding wheel for crankshaft grinding and manufacturing method thereof
The invention relates to a ceramic microcrystal fused alumina grinding wheel for crankshaft grinding and a manufacturing method thereof. The grinding wheel is characterized in that a grinding portion comprises 10-50 parts of ceramic microcrystal fused alumina grinding materials with the granularity being 46-80#, 20-40 parts of monocrystal fused alumina materials with the granularity being 60-100#, 10-60 parts of white fused alumina grinding materials with the granularity being 60-100#, 10-20 parts of low-temperature ceramic bond, 5-10 parts of pore-forming agents, 2-4 parts of crystal whisker materials, 3-6 parts of wetting agents and 0.6-1.2 parts of coloring agents, and a clamping portion comprises 100 parts of white fused alumina grinding materials with the granularity being 60-100#, 10-20 parts of low-temperature ceramic bond, 2-4 parts of crystal whisker materials and 4-6 parts of wetting agents. The ceramic microcrystal fused alumina grinding wheel has the advantages of being strong in grinding capacity, high in machining precision and efficiency, long in service life, good in heat dissipation, low in finishing frequency, good in self-sharpening performance, good in processing surface roughness, long in service life and much cheaper than a superhard material grinding wheel, not burning workpieces and saving the cost.
