CBN grinding wheel dressing cycle is long

  CBN abrasive hardness higher than normal , high hardness means more sharp

and cutting stronger ; CBN has a higher wear resistance, means that it is

harder than ordinary abrasive wear ; ability  sds drill bit  to maintain the shape of CBN

abrasive high-performance one of the main characteristics of the abrasive ;

CBN high compressive strength , which means that in the harsh conditions of

use it can remain intact and not broken particles ; CBN has good thermal

conductivity , the grinding can be achieved when cold cutting .
1, high hardness, high toughness CBN human hardness only to diamond synthesis

of superhard material is much higher than the normal corundum and silicon

carbide abrasive , and thus has a flap wheels  better cutting ability , more sharp.
2 , high temperature resistance , good thermal stability .
3 , chemical inertness . 4 , good thermal conductivity . 5, the grinding

performance, good surface quality 6 , abrasion resistance and longer life.

CBN grinding wheel ratio up to 3500-5500 , a hundred times more than ordinary

high corundum grinding wheel , diamond grinding wheel 3-5 times higher than

that . 7 , environmental pollution, energy saving. Without too much powder

dust. 8 , high efficiency, good overall 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  stone drill bits conducive to the machining operation .
   Cubic boron nitride (CBN) is not suitable for grinding carbide and non-

metallic hard materials . In the grinding temperatures , CBN case of alkaline

aqueous chemical reaction occurs , CBN wheel at 300 ℃ alkaline solution will

be decomposed in boiling water to trace decomposition destroyed crystal

grains will result , so that when grinding only use oil-based coolant , not

water-based coolant.
