Sharpening of standard inserts in superhard tools

2023-05-06 15:53:57

What is superhard cutting tools?

Superhard tools are cutting tools that use materials with exceptional hardness and wear resistance, often beyond that of common tool materials like carbide or high-speed steel. Diamond and cubic boron nitride (CBN) are the most common superhard materials used in cutting tools due to their extreme hardness, toughness, and chemical stability. Superhard tools are more expensive than traditional cutting tools but can offer significant benefits in terms of longer tool life, higher cutting speeds, and improved surface finish on the machined parts. They are commonly used in the machining of high-strength and abrasive materials such as hardened steels, cast irons, and composites.

What is cutting edge of tools?

The part where the rake face and the main flank intersect is the main cutting edge; there is also a secondary cutting edge on the insert, which is where the rake face and the secondary relief corner intersect; the tip part is the main cutting edge and the secondary Where the cutting edges intersect.

How to process the edge of cutting tools?

1.Grinding-PCD/PCBN grinding machine

2.Laser-using fiber laser grinding machine

3.EDM-wire cutting machine

Laser machining and EDM maching are used in rough machining of cutting edge.In order to achieve high-precision edge grinding, it is necessary to use a high-precision grinding machine with a diamond grinding wheel for processing。

    Ceramic CBN grinding wheel for grinding rotor

    As key equipment in modern energy conversion and power systems, turbines require extremely high precision and quality in their manufacturing and maintenance processes. The grinding of turbine rotor grooves is one of the important processes, which directly affects the performance and life of the turbine. In recent years, ceramic CBN (cubic boron nitride) grinding wheels have gradually become an ideal choice for grinding turbine rotor grooves due to their excellent hardness, wear resistance and thermal stability. This article will explore the application and advantages of ceramic CBN grinding wheels in turbine rotor groove grinding.
