1. Processing material(1) High hardness cast iron (hardness above HSD75)
For example, high-chromium cast iron, alloy cast iron, nickel-hard cast iron, and white cast iron all belong to high-hardness cast iron. Typical parts include rolls and industrial pumps. Halnn Superhard has launched BN-K1 grade and BN-K10 grade for high-hardness cast iron, which has significant advantages.
(2) High hardness steel parts (hardness HRC45-68)
Such as high-manganese steel, high-speed steel, hardened steel, etc. Typical parts include rolling mortar wall, high-speed steel roll, hardened gear/gear shaft, bearing, ball screw, mold, etc. Halnn recommends BN-S10, BN-S20, BN-S200, BN-H10, and BN-H21 grades for high hardness steel parts.
(3) Ordinary gray cast iron (HT150/200/250/300)
For example, the engine block/cylinder head, brake disc, brake drum, pulley, clutch pressure plate, etc. are all gray iron castings. Halnn Superhard recommends BN-S300 grade and BNK30 grade for high-speed machining.
(4) Other difficult-to-process materials
Such as powder metallurgy, superalloy materials, and nickel-based, iron-based, cobalt-based, and other high-hardness surfacing/spray welding/laser cladding/thermal spraying material workpieces. Halnn Superhard recommends BN-S300, BN-S200, BDN80, and other grades for processing.

3. Common processing processes
Heavy-duty cutting: large-scale parts are turned with a large depth of cut. Halnn CBN tools BN-K1 and BN-S20 have the characteristics of high strength, wear resistance, and impact resistance. Compared with other tools, they can Obtain higher processing efficiency, widely used in energy, mining, steel, and metallurgical industries.
High-speed cutting: refers to the cutting process performed at a speed much higher than the conventional cutting speed. Currently, the BNK30 grade of the Halnn superhard tool can be processed at a cutting speed of 3000m/min at a high speed, Nearly 10 times higher than the limited cutting speed of carbide tools.
Substituting turning for grinding: It is a process that uses turning of hardened steel as the final finishing process. Its processing quality can replace the grinding process. Halnn superhard cutting tools have the characteristics of high hardness and strong fracture resistance, and have formed a From continuous-intermittent, roughing - super finishing, a complete set of cutting tool solutions in the field of "turning instead of grinding" in hard machining.
Dry cutting: It is a cutting that does not use cooling lubricant at all; it does not affect the environment and is convenient for chip recycling. It is a "green manufacturing" process. At present, Halnn can perform dry cutting on cast iron, hard steel, aluminum alloy, superalloy, carbon fiber composite materials, etc., to help green manufacturing.
