Grinding wheel grinding method

  • Solution to the problem of clogging in stainless steel and the choice of stainless steel grinding wheel: 1. When grinding stainless steel, reducing the adhesion and blocking of the 14 inches cutting disc is an important factor to improve the grinding efficiency. The grinding wheel should be often trimmed during processing to keep the cutting edge sharp. 2. Abrasive selection is very important: CBN (cubic boron nitride) grinding wheel resin binder. Suitable for fine grinding of stainless steel, he has high hardness, good thermal stability, good chemical inertness, and high-temperature resistant abrasives are not easy to become dull. The SM (SG) grinding wheel has a microcrystalline structure, can be automatically detached and has a good self-sharpness. Green carbon (GC) grinding wheels are widely used in grinding 400 series stainless steel because of their brittleness and sharpness. 3. The grinding wheel for grinding stainless steel is made of the self-sharpening grinding wheel, and the hardness is G-K grade. Based on J level. 4. In order to reduce the adhesion and obstruction of thehigh quality cutting disc supplier during grinding and to ensure the smoothness, a coarse-grained grinding wheel should be used. For coarse grinding, the particle size of No. 46 is used, and for fine grinding, the particle size of No. 60-80 is used. 5. The grinding fluid must be balanced with both lubrication and cleaning. The supply is sufficient. The emulsion with extreme surface tension and optional extreme pressure additives can be used to obtain high surface quality. 6. The choice of the grinding amount can be determined according to the machining allowance, but the grinding depth cannot be less than 0.01mm. Generally, the plane feed can reach 0.03, and the outer circle and the centerless can be larger. (China Metallurgical News)
