PCD center point for machining high precison shaft
The advantages of PCD dead centers
? Ultra-high wear resistance, service life of 80-180 times that of hard alloy center.
? Good thermal conductivity, reduce the friction heat grnerated in the work and avoid the central hole of the workpiece being burned and deformed, causing changes in the central position and affecting the machining accuracy.
? The friction coefficient is much lower which cangreatly reduce the friction resistance. And the vibration of workpiece, to improve the processing accuracy.
? Polycrystalline diamond under 650° showed good chemical inertness, resistant to strong acid, alkali, suitable for all kinds of operating mode under the condition of work.

PCD tools are made of polycrystalline diamond tips and cemented carbide substrates sintered at high temperature and high pressure.The production process of PCD tools includes cutting of PCD blanks,welding PCD blanks to cemented carbide substrate ,cutting tools grinding, quality inspection, etc.Moresuperhard can provide all the consumables needed to produce PCD tools.
Cermet are widely used in various industries due to their excellent performance, but their grinding difficulty is often difficult. Although the hardness of metal ceramics is similar to that of cemented carbide, its processing challenges mainly come from high density and low thermal conductivity. This article will explore the characteristics of metal ceramic grinding and how to choose the right grinding wheel and binder to improve processing efficiency.
