Different components:

1. CBN insert: Artificial cubic boron nitride cutting tool, at high temperature can also maintain the characteristics of high hardness, mainly for processing iron parts.

2. Ceramic insert: Metals or nonmetals combined with oxygen (O), nitrogen (N), carbon (C), and other elements are called ceramics. After sintering, it can be used as a cutting tool.

Comprehensive analysis:
A total of 100 units were tested. The first 7 units were tested to the limit. The maximum load of the machine was set at 25%.
After the sharpening, the load of the machine tool can be reduced, the grinding force of the grinding wheel can be maintained, and the outer diameter of the grinding wheel does not change much. In conclusion, the hardness of the grinding wheel is hard, the grinding wheel is easy to block holes, and the grinding wheel maintainability is good.

Diameter of the grinding wheel is too large, the contact arc between the grinding wheel and the workpiece will increase, which will increase the grinding heat and make cooling and row cutting difficult. If the diameter of the grinding wheel is too small, it is difficult to achieve the ideal grinding speed (30m/s~50m/s), which increases the grinding thickness, increases the conformity of the grinding grains, and is easy to blunt, which increases the surface roughness of the inner hole and reduces the production efficiency when grinding the hole of workpiece.

Usually, as customer said “anything” is not changed, same grinding wheel, same work piece, same grinding machine, same stuff and same grinding condition. We think they change a very small thing “feeding speed”. Because they want to improve the grinding efficiency, increase the feeding speed is an easy way.
However, if increase the feeding speed too much, it makes grinding wheel wears out very quickly. The grinding efficiency is improved, but grinding wheel wears too fast. We recommend customer choose a reasonable feeding speed. That’s not a big problem, but it makes your production cost increased.

Cylindrical vitrified diamond grinding wheel is used for PCD reamers grinding. It enjoys high grinding power,long working life, good surface quality.

Double-end grinding is to grind the two end faces of the workpiece at the same time with two oppositely arranged grinding wheels. It is mainly used for grinding the two end faces of discs, sleeve parts or sheet parts. It is the most effective method for finishing the end faces of flat workpieces. one. Widely used in hydraulic and pneumatic components, hydraulic motor parts, automotive steering pump parts, refrigeration compressor parts, oil pump nozzle parts, engine parts, high-precision bearings, seals, piston rings, measuring tools, molds, instruments, hard End surface processing of high-quality alloy blades, ceramic valve cores, magnetic materials and other products.
