Ceramic Grinding Wheel With High Efficiency
Ceramic wheel characteristics
1, high hardness, high toughness cubic boron nitride (CBN) is the hardness of human synthesis after the diamond superhard material is much higher than ordinary corundum and silicon carbide abrasive, which has better cutting capacity, more sharp
2, high temperature, good thermal stability. Cubic boron nitride can withstand 1250-1350 degrees Celsius high temperature, higher than the heat resistance of diamond 800 degrees Celsius; Vitrified Grinding Wheel in grinding and cutting iron material, there will be no dirt phenomenon, in the grinding hardened steel, high vanadium high speed Steel, aluminum and other high-speed steel grinding temperature is more sensitive to the metal material is the best grinding wheel. 3, strong chemical inertia. Cobalt boron nitride is not easy to produce chemical reactions with iron elements, so for a variety of high-speed steel, tool steel, die steel, high alloy hardened steel, chrome steel, nickel alloy, powder metallurgy steel and high temperature alloys and other high temperature The grinding of materials with low thermal conductivity is very suitable.
4, good thermal conductivity. CBN thermal conductivity up to several times to 100 times the corundum wheel, Vitrified Grinding Wheel which can quickly export grinding heat to reduce the workpiece thermal deformation. It is very suitable for grinding materials with low thermal conductivity. All kinds of spray (welding) materials: nickel, iron, etc .; wear-resistant cast iron materials: vanadium - titanium cast iron, Vitrified Grinding Wheel high phosphorus cast iron, chilled cast iron, etc .; titanium alloy: such as TC4.
5, grinding performance is good, good quality processing surface. As the cubic boron nitride abrasive to maintain long-term abrasive micro-blade sharpness, will be processed workpiece processing accuracy and surface roughness values have reached the ideal effect, so the workpiece can increase the durability of 10% -30% The So even if the batch processing of the workpiece, will always get a higher shape, accuracy and consistency. CBN grinding wheel grinding can get high dimensional accuracy and low surface roughness, Vitrified Grinding Wheel the processing surface is not easy to produce cracks and burns, residual stress is small. Processing surface quality is improved, generally no cracks, easy to burn, and can get residual compressive stress, significantly improve the fatigue strength of the workpiece, usually, Vitrified Grinding Wheel the wear resistance of the workpiece can be increased by 30-50%.
6, wear resistance, long life CBN grinding wheel grinding ratio of up to 3500-5500, 100 times higher than ordinary corundum wheel, 3-5 times higher than the diamond grinding wheel.
7, environmental pollution, energy saving. Not too much powder dust.
8, high efficiency, comprehensive economic benefits. Grinding sharp, small grinding force, CBN wheel dressing cycle is long, the amount of repair less, long replacement time; long life cycle, high grinding ratio, access to better economy, the use of good shape retention, Vitrified Grinding Wheel Replace the grinding wheel and dressing wheel, save working hours, improve working conditions, is conducive to processing operations.
Ceramic grinding wheel use range
1, the grinding of the mild steel is preferred. A lot of experience on the import and domestic stainless steel and other mild steel grinding to achieve a very good effect, and the efficiency of about 100% increase in economic efficiency by 200%.
2, in the automatic machine on the mass production of the workpiece (miniature bearings, air compressor, crankshaft, camshaft, high precision thread, instrument, etc.) grinding and final grinding.
3, require the grinding wheel has a good edge to maintain the complex surface of the workpiece (shaper cutter, broach, high precision gear, by the mold, punch, etc.) grinding.
4, large-scale precision workpiece (machine tool guide, Vitrified Grinding Wheel high-precision screw, etc.) grinding and grinding. The use of ordinary abrasive workpiece is often due to high grinding temperature and easy to cause greater deformation, the best choice is the CBN wheel.
5, on the heat-resistant steel and high hardness (HRC55 above) made of alloy steel precision parts and grinding and grinding. These parts with ordinary abrasive due to abrasive consumption or blunt too fast and can not get high precision. 6, for special steel such as tungsten, tungsten and molybdenum high-speed steel, vanadium alloy steel, cobalt alloy steel, special high-speed steel tool sharpening, difficult to process heat-resistant steel parts of the ultra-finishing, and other steel quenching tools honing.
7, containing tungsten, tungsten and molybdenum and other high-speed steel, especially vanadium alloy steel, cobalt alloy steel and other special high-speed steel tool grinding and precision.
8, by the heat, stainless steel and high hardness (HRC55 above) of the alloy steel made of precision parts of the fine grinding and final grinding. Vitrified Grinding Wheel These parts with ordinary abrasive grinding consumption is too large or blunt too fast and can not get high accuracy.
9, in automatic or semi-automatic machine tools on the mass production of parts such as instrumentation and micro-bearing parts
10, the titanium alloy grinding CBN is the best grinding wheel selection.
