DNGA CNGA SNGA TNGA VNGA WNGA CNC CBN Inserts for Superhard Materials

Product description

Introduction to CBN inserts

Welded cubic boron nitride blade

The tip is made of cubic boron nitride material, and the intermediate matrix is made of cemented carbide material. The CBN tip provides high hardness, high wear resistance and good thermal stability for cutting processing; the cemented carbide matrix has high strength and toughness, can withstand cutting force and impact, and provides reliable support for the CBN tip. There is a center hole for positioning, which can replace the coated blade. Common models include CNGA, SNGA, VNGA, etc.

Features of tungsten carbide CBN insert

Performance characteristics

1.High hardness and wear resistance: The hardness is second only to diamond, up to 3000-5000HV, suitable for processing high-hardness ferrous metal materials, such as hardened steel, mold steel, etc.

2.Good thermal stability: The heat resistance can reach 1400-1500℃, which is twice as high as the heat resistance of diamond, and can be used for high-speed turning.

3.Good chemical stability: It will not react chemically with iron materials at 1200-1300℃, and there will be no sharp wear during high-temperature cutting.

4.Good thermal conductivity: Much higher than high-speed steel and cemented carbide, which is conducive to reducing the temperature of the cutting area and reducing diffusion wear.

Low friction coefficient: The cutting force generated during cutting is small, which can effectively improve the surface quality.

The application areas of CBN insert

Automobile manufacturing: commonly used for processing engine parts and transmission system parts, such as high-speed hard turning of hardened steel gears, bearings, and crankshafts, which can replace grinding.

Aerospace: used to process difficult-to-process materials such as titanium alloys and nickel-based superalloys, such as high-temperature alloy material processing of turbine engine blades.

Mold manufacturing: can achieve efficient processing of hard mold steel (HRC 45 or above), improve processing accuracy and surface finish.

Heavy machinery manufacturing: used for processing high-strength steel parts required in large equipment, such as rough and fine processing of chilled cast iron rolls and high-chromium cast iron.
