With the development of industrialization and the improvement of market requirements, for high-precision shaft rotary products, high-hardness cemented carbide, alloy steel, wear-resistant cast iron, ceramics and other products that require top grinding and top turning, the top of the lathe center must be used ,
     The highest precision lather center is the dead center. Compared with the live center, the dead center can avoid the shortcomings of low machining accuracy caused by the change of the machining standard. However, the dead center is in direct contact with the workpiece during the working process, and relative sliding friction occurs. Therefore, super high wear resistance is required for top materials.
     At present, most of the tungsten carbide dead center are used in the market, but for some high-hardness products, the tungsten carbide materials wear extremely fast during use, and the machining accuracy cannot be guaranteed, the service life is poor, and the dead center are frequently replaced each time. Replacing the dead center requires fine-tuning of the equipment, which causes too much redundant labor for the workers, reduces the stability of the product, and the processing efficiency is greatly affected at the same time.

In response to the current market requirement, the company relies on 20 years of experience in superhard material processing, and developed a set of production processes suitable for high hardness and difficult processing of diamond polycrystalline materials. The diamond polycrystalline dead center has a long service life and high precision, and has been widely recognized by the market.

Diamond polycrystalline dead center can also be called high-precision dead center and high-precision dead center. The current precision can reach within 0.003mm, and some can even reach 0.001mm. our pcd dead center have lower price and can fast delivery,and have high wear resistance.
