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.
Standard PCD/PCBN inserts
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。
