PCD Insert Grade Selection
Selecting the optimum grade of PCD tooling for a specific application is generally a function of surface finish requirements and tool life expectations. Material removal rates, tool geometries, and material characteristics also affect the relationship between machining productivity, tool life and surface finish.
Coarse grade PCD inserts are designed with a larger diamond particle size than a fine grade PCD. Generally, PCD inserts with larger diamond particles exhibit greater abrasion resistance, but result in a rougher cutting edge. Conversely, smaller diamond particles will result in a sharper cutting edge, producing a superior workpiece surface finish, but tool life is reduced.
In conjunction with major industry users and tool fabricators, MASTERTECH has developed and optimized PCD tooling to meet specific application needs.
