PCD Dead Center for High Precision Shaft Machining

2022-11-29 14:25:22

PCD center point for machining high precison shaft

At present, most of the tungsten carbide dead centers are used in the market, but for some high-end, high-hardness products, tungsten carbide materials wear extremely fast during use, processing accuracy cannot be guaranteed, and poor service life, resulting in dead centers frequent  replacements. In addition, the equipment needs to be fine-tuned every time the dead centers is replaced, which causes too much redundant labor for the workers, which reduces the stability of the product and also greatly affects the processing efficiency.
For the current market demand,we have specially developed the superhard material diamond dead center. The diamond dead center is made of diamond polycrstalline material.Using special techniques embedded in the dead center base,The center base is made of high strength steel. Diamond polycrystalline materials are second only to natural diamond in hardness.

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.

 

The specification of PCD dead center
The concentricity of all diamond tip <= 0.003 mm, which is very suitable for top grinding of high precision shaft products

    How to grind sapphire workpieces

    Sapphire consists of Al2O3 and has a Mohs hardness of 9, which is second only to superhard materials in hardness. Due to its superior light transmittance and wear resistance, it is mostly used in the substrate of LED light-emitting components, optical windows, and watch cases of high-end watches and cell phone cameras, etc.The processing process usually requires high precision, fast processing efficiency, low material loss and a clean working environment. Diamond is the hardest and most wear-resistant material in nature, so diamond tools are the best choice for processing sapphire materials.
