The PSD, purity and shape for each batch of diamond powder will be analyzed by the laser particle size analyzer.
The magnetic performance, physical property and mechanical property for each batch of WC-Co materials need to be tested.
A unique identification code will be used for each batch of goods for monitoring, the status in each process will be recorded to make sure any abnormal traceable.
Monitoring points are set in assembling, synthetic, grinding, machining and CNC machining process to control the entire process perfectly.
The abnormal control process will be started once any abnormal parameter appeared to avoid the unqualified products coming into the finished product stage.
Sizes inspection including: diameter, height, diamond thickness, chamfer and geometrical sizes(verticality, roundness, flatness, parallelism, value of R)
Appearance inspection including: cracks, edge chips, scratch, layering, pit, black spot, irregular color, corrosion, etc. The appearance is inspected by 20X microscope.
The internal defect was inspected by C-Scan
Sampling test for the main performance wear resistance, impact resistance and heat stability regularly
Wear Resistance Test
Impact Resistance Test
