Wear Resistance Test:
Vertical Turret Lathe (VTL) this apparatus is the large VTL used for abrasion performance testing of PDC cutters. The VTL machine is performed both in wet and dry environment, on the granite plana. the PDC cutter cuts through granite in a certain number of circles with a certain feed, we observe temperature and cutting forces, and measure cutter consumption volume. This can evaluate cutters' abrasion resistance and thermal stability.
Impact Resistance Test:
The test will use a steel ball with agreed size dropping from different heights with regular dropping times which will occur a certain energy. It can measure the impact performance of PDC cutters.
Ultrasonic C Scan:
It is used for inspecting the interface between diamond layer and tungsten carbide to make sure the sintered procedure is in
accordance with requirement. It is the very important factor to evaluate the inside quality of PDC cutter.
Electron Scanning Microscope:
This apparatus can zoom hundreds of times of the picture on the cross profile of PDC cutter which will be very helpful to analyze the micro bonded structure inside of the cutter.
