PDC the hardness and abrasion resistance of diamond with the impact resistance of tungsten carbide,and provides faster,more durable and more cost-effective drilling.
PCD work layer & tungsten carbide part is used mesh connect method to make it stronger . When using PDC , PDC work layer is not easy to take off and more abrasive resistant .
1) With feature of high working efficiency, smooth surface2) Advanced technics and strict process control3) Long lifespan and stable performance4) Competitive price and superior quality 5) Excellent service
1)high hardness and wearability 2)sorts of shapes and sizes 3)high toughness
1)For oil drilling2)For gas drilling 3)For mining bits4)For coal drilling5)For well drilling
1) Raw material checking , grit ,size , surface, sample testing 2) Inner assembly3) External assembly4)Press by Cubic press machine with high temperature & high pressure (first testing)5)PCD work layer process 6)Cylindrical roughing processing , finishing processing 7)Tungsten carbide flat polishing processing 8)PCD work layer , Tungsten carbide layer chamfer processing 9)Quality testing , get in stock Notice :When using , don't let temperature higher than 700 degree
Impact resistant testing Temperature resistant testingWorking lifespan testing Note: When using , don't let temperature higher than 700 degree
When using , drilling requires high impact resistance ,when finished a lot PDC , we will choose 5% sample for testing in impact resistance .
When drilling , long time drilling will make its temperature higher , so PDC has to have an ability to face high temperature drilling .
In order to guarantee our working life , we will choose some sample for testing in working life . Our testing way is drilling granite , granite hardness is higher than other geological .
