Ultra hard grinding wheel of knowledge base
Brief introduction of superhard grinding wheel
Ultra hard grinding of diamond and cubic boron nitride is divided into two categories. Due to the abrasive hardness of ultra hard grinding wheel used far more corundum and silicon carbide abrasive hardness, so it can be difficult to machine materials processing of conventional abrasive wheel.
Diamond and cubic boron nitride (CBN) grinding wheel is the main characteristics of high hardness, high thermal conductivity, high sharpness, resulting in high efficiency of grinding, grinding at high speed under the condition of ultra hard grinding wheel grinding ratio can reach more than one hundred times the corundum abrasive grinding wheel. At the same time, the grinding force of superhard grinding wheel grinding wheel than ordinary small, less power consumption, saving power; because of sharp grinding, even in the grinding efficiency is high, the temperature in the grinding zone than the ordinary abrasive, avoid the defect of surface burns, cracks, reduce the plastic deformation, the shape and the the size and accuracy of the workpiece, and the workpiece can increase the service life.
On the requirement of the parts of increasingly sophisticated today, the popularity of super hard grinding wheel in the modern industrial machinery processing has become a trend, it greatly reduces the number of replacement of grinding wheel, dressing interval extension, improve labor productivity, reduce the consumption of energy and labor, and reduces the production cost, but also improve the safety of the production process in the.
Application of super hard grinding wheel
1.CBN grinding wheel: the main object is hard and tough materials such as: alloy steel, high speed steel, mould steel, hardened steel, cast iron, ductile cast iron, chilled cast iron, nickel, titanium alloy eutectic alloy cast iron, iron group metal materials etc..
2: the main object of diamond grinding wheel grinding of hard and brittle materials such as: hard alloy, optical glass, semiconductor materials, magnetic materials, crystal, agate, precious stones.
3.CBN diamond abrasive wheel: cast iron, cast steel, density etc..
