Analytical chemical inertness CBN diamond grinding wheel

 Analytical chemical inertness CBN diamond grinding wheel (A) chemical inertness. Cubic boron nitride and iron group elements is not easy to produce a chemical reaction, so for a variety of cutting disc   high-speed steel, tool steel, tool steel, high alloy hardened steel, chromium steel, nickel alloys, powder metallurgy steel and high temperature alloys such as high  temperature, high hardness , low thermal conductivity of the material is very suitable for grinding.
(2) good thermal conductivity. CBN grinding wheel corundum thermal conductivity up to several hundred times, and thus be able to export the grinding heat quickly, reducing workpiece thermal deformation. Low thermal conductivity of the material for grinding is very appropriate. A variety of spray (welding) Material: nickel, iron, etc.; cast iron type material: vanadium - titanium cast iron, high-phosphorus iron, chilled cast iron, etc.; titanium: such as TC4 and so on.
(3) high efficiency, good overall  abrasive tools economic efficiency. Sharp grinding, grinding force is small, CBN grinding wheel dressing cycle is long, finishing less the amount, the replacement for a long time; long life cycle, grinding ratio, getting a better economy, in use to maintain good shape, without regular replacement wheel and wheel dressing, saving time, improving working conditions, is conducive to the machining operation.
The wheel parameters are abrasive, viscosity, hardness, binders, shape, size and so on.
Since wheel usually work at high speed, thus turning test should be carried out before use (guaranteed wheel at the maximum operating speed, not break) and static balance test (to prevent machine  metal cutting wheel vibrations caused by the work).
Wheel made of various shapes and sizes, several commonly used wheel shape, size, code and uses the wheel diameter selected to be larger as far as possible, to improve the grinding wheel peripheral speed, so that the productivity of the process and improve the grinding surface Roughness advantageous, in addition, the stiffness and power tools permit conditions, such as the selection wheel larger width, the same can improve productivity and reduce the roughness receiving effect, but the high heat-sensitive material in the grinding, to avoid artifacts burns and surface cracks.
