PDC with diamond grinding wheel

Resin bond diamond grinding wheel for grinding diamond composite film in the presence of grinding efficiency , low processing composite sheet size consistency is poor, grinding noise and other issues, knot
Together vitrified diamond wheel features green concrete blades  which are designed with a diamond wheel can be developed instead of vitrified resin bond to overcome these shortcomings. Its main characteristics and test results are summarized as follows:
1 . For high-temperature stability of the diamond abrasive tests and found that above 700 ℃, diamond abrasive occurs in air oxidation , the diamond
Abrasive damage ; diamond abrasive high degree of thermal damage to the diamond abrasive grade, particle size about the same temperature , the lower the grade , the finer the particle size , the diamond abrasive by a higher degree of heat damage ; engineer changes sintering process  step pads reduces 750 ℃ high temperature diamond abrasive itself against thermal damage . Combined with diamond abrasives
Thermal stability and PDC diamond grinding characteristics of selected ceramic composite sheet as grinding diamond wheel .
 PDC grinding tests , processing coal geology PDC life in 1600-2000 pieces ; processing performance PDC oil life in 1200-1400 film. And resin bond compared to the grinding process, the grinding is mainly found in the composite film rubbed off the excess composite sheet cylindrical diamond , the diamond
Very hard , when using resin bonded grinding wheel , since the resin bond diamond wheel grinding wheel in order to  diamond cup wheels ensure durability, generally done very dense, almost no gas
Hole , so grinding grinding force particularly large, grinding spindle great harm ; And very sharp wheel , grinding wheel will feed large knife , and send clamor cry ; mill
Cutting efficiency is very low . The vitrified diamond grinding wheel due to porosity, good self-sharpening wheel for grinding spindle hurt small ; wheel sharp , high grinding efficiency
