DNGN CBN Inserts

Features

Introduction

The shape of DN series solid CBN inserts is 55 °diamond shape. Generally, polycrystalline cubic boron nitride is used. There are three types of BTS2800, BTS7600, and BTS7800. It is synthesized by high pressure and high temperature of a six-sided top hydraulic machine. After synthesis, it has high wear resistance, impact resistance and chemical stability. Solid CBN inserts are mostly used for cutting hardened steel, cold-hardened cast iron and surface thermal spray materials, The machining of medium hardness materials often does not reflect the excellent cutting performance of CBN inserts. When machining workpieces of HRC45 or higher, the inserts shows unparalleled superhard performance. Its service life is more than 10 times longer than that of cemented carbide tools.

Advantages

Characteristic	Advantages
1.Widely application	Can meet finishing, semi-finishing and roughing.
2.High fracture toughnes	Continuous cutting, general cutting, and interrupted cuttin
3.High bending strength	Large cutting depth(<1/3 length of insert)
4.High temperature resistanc	Can withstand high temperature of 1400 degree
5.More cutting edges	Unlimited regrind, high blade utilization

Processing material: Various cast iron, hardened steel, ductile cast iron, chilled cast iron, high chromium cast iron, high manganese steel, high temperature hard alloy, powder metallurgy, alloy steel, tool steel, mold steel and other difficult-to-machine metal materials.

Machining workpiece: Hardened bearing steel, rolls, brake discs, slurry pumps, quenched gears, ball screws, high temperature alloys, various hard-to-machine high-hardness workpieces with Rockwell hardness between HRC45-70.

CBN inserts are super-hard finishing turning inserts. The inserts have high abrasion resistance, and the surface finish is good. The surface finish can reach Ra0.8. Turning instead of grinding greatly improves production efficiency and reduces production costs. It is widely used in Medical equipment, automotive parts, aerospace processing.
