Application of cermet technology in diamond wheel field

As a strategic partner of our company, Changsha Sapu New Material Co., Ltd. is a professional manufacturer of high-quality diamond and CBN grinding wheels, as a supplier and service provider of high speed and high quality grinding system technology solutions, with completely independent intellectual property rights.
 
The diamond grinding wheel produced by Diaer is a cermet based grinding wheel. Among them, cermet is a new material independently developed and designed by Chengdu Meiselui, which has the following characteristics:
  • 1. Ceramic metal has good stress control performance. The cermet is single-phase uniform structure, has good diamond surface wettability, in the synthesis process has good compressive stress generation and release performance, to ensure the good interface between the cement and diamond /CBN.
  • 2. Ceramics have good thermal properties. Compared with the conventional ceramic materials, the thermal conductivity of the cermet is increased by 10-100 times. The high thermal conductivity ensures the uniform transfer of heat in the grinding process of the diamond wheel, which is conducive to improving the grinding speed and grinding speed of the wheel.
  • 3. Ceramic metal has good mechanical properties. The cermet has moderate hardness and high strength. The high strength ensures that the diamond grinding wheel has good shape retention, and the moderate hardness ensures that the diamond grinding wheel has good cutting edge and dressing performance.
 
On the other hand, in the process of producing diamond grinding wheel, the following preparation technologies are independently designed to make full use of the performance of the new cermet material and ensure the high performance characteristics of the whole diamond grinding wheel.
  • 1. Self-consistent hole making technology on working layer of superhard grinding wheel.
  • 2. High blade height technology.
  • 3. Self-cutting and self-sharpening technology.
  • 4. High protection type & easy repair coupling technology.
  • 5. High strength metallurgy combined with liquid phase full equilibrium diffusion integral forming technology at the internal interface.
 
Using the new cermet as the adhesive and combining with the above preparation technology, the cermet foundation grinding wheel produced has the following characteristics in terms of structure and performance:
  • 1. The working layer of the grinding wheel has high chip removal performance and high gyratory strength at the same time.
  • 2. Grinding wheel has both high cutting edge and shape retention.
  • 3. Grinding wheel substrate is characterized by light weight, high thermal conductivity and resistance to environmental corrosion.
  • 4. The working layer and matrix of grinding wheel realize full metallurgical combination, which has high interface stability.
  • 5. The physical and mechanical properties of the whole grinding wheel are highly matched.
