Compared with old generation of hard alloy or alloy steel materials of dead center, TKD has launched new high precision PCD(polycrystalline diamond) equipped dead centers, after 2 years tracking domestic initial users, we help to solve the problems of all using conditions.And summarized the set of usage tips and notice to recommend our new users.
Product description
The new generation diamond dead center is made of diamond polycrystalline material using special techniques embedded in the dead center base which is made of high strength steel.
Material Technical data:
Polycrystalline diamond tiphardness: > HV8000, 80~180 times harder than hardalloy,
Wear ratio > 250,000,
Thermal conductivity > 700W/mk,
1.5~9 times that of hard alloy,
Friction coefficient > 0.1-0.3 (hard alloy is 0.4-1);
Advantages
Because of the above excellent properties of polycrystalline diamond materials, the advantages of the PCD dead centerare mainly include:
1. Ultra-high wear resistance and service life of 80-180 times that of hard alloy center.
2. Good thermal conductivity, reduce the friction heat generated 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.
3. The friction coefficient is much lower which cangreatly reduce the friction resistance, and the vibration of workpiece, to improve the processing accuracy.
4. Polycrystalline diamond under 650° showed good chemical inertness, resistant to strong acid,alkali,suitablefor all kinds of operating mode under the condition of work.
