Solid CBN Inserts

The RCGX series Solid CBN insert is a CBN insert developed and produced exclusively by our company. It adopts a 120 °cone positioning to tightly fix the insert and the cutter body to complete the cutting of difficult-to-machine material workpieces. The service life is 5-10 times longer than that of carbide tools and ceramic tools.

The shape of the WNGN series solid CBN insert is 80 °hexagon, which has higher hardness, wear resistance and heat resistance than cemented carbide and ceramic tools. Can use high cutting speed and high hardness (HS58-68) cold hard cast iron, the cutting effect is significantly higher than the use of other materials tools.

SCGN0904 and SCGN1204 CBN inserts show better machining results in the machining of automotive brake discs. They can be roughing and finishing the end faces, outer circles and inner holes of brake discs. Cutting depth ap = 0.2mm, linear speed Vc = 1000m / min, feed amount f = 0.1mm / r.

TNGN series cubic boron nitride inserts have a stable regular triangle shape with superior cutting performance and are suitable for high-speed dry cutting. They are widely used in gray cast iron, ductile cast iron, wear-resistant alloy cast iron and various cast steels and hardened steel Processing, can withstand large cutting depth, large cutting, can adapt to intermittent cutting, cutting depth to control the inserts radius is preferably within two thirds.

The SN series solid CBN inserts (referred to as CBN blades) are square in shape, and there are many models and specifications. Under the high temperature and high pressure of the six-sided top hydraulic press, it is sintered and synthesized, which has strong wear resistance, heat resistance and chemical stability. It can efficiently turn cast iron brake discs, cast iron brake drums, boron cast iron cylinder liners, cast iron clutch pressure discs and other automotive parts to realizing turning instead of grinding. SN series CBN inserts are matched with 45 °, 75 °, 83 ° and other external turning tool holders. There are three types of R, L and N.

When processing hardened steel with PCBN tools, the quenching hardness of the workpiece is required to be higher than 45～55HRC. When processing hard cast iron, as long as the hardness reaches the medium hardness level (45HRC), good processing results will be achieved. For example, the exhaust valve seat on the cylinder head of an automobile engine is made of high chromium alloy cast iron material containing copper and molybdenum, and its hardness is generally about 44HRC

Features

SCGN0904 and SCGN1204 CBN inserts show better machining results in the machining of automotive brake discs. They can be roughing and finishing the end faces, outer circles and inner holes of brake discs. Cutting depth ap = 0.2mm, linear speed Vc = 1000m / min, feed amount f = 0.1mm / r.
1. Cubic boron nitride inserts has the advantages of high hardness, good abrasion resistance and high heat resistance. Selecting the appropriate cutting amount can achieve the purpose of improving production efficiency and ensuring processing quality.
2. For continuous cutting, the appropriate cutting amount is usually determined according to the wear resistance of the cubic boron nitride tool.
3. Cubic boron nitride cutters have superior high temperature performance and are best suited for high speed cutting. The effect of cutting speed on tool durability is less than when cutting with carbide tools.
