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.
