(1) high hardness cast iron
? For example, high chromium cast iron, alloy cast iron, nickel hard cast iron and white cast iron all belong to high hardness cast iron, and typical parts include rollers and industrial pumps. CY 1 and HJ3 series materials are commonly used in high hardness cast iron, which have obvious advantages. Rough turning can be carried out on the casting blank with sand inclusion and air holes.
(2) High hardness steel parts (hardness above HRC45)
? Such as high manganese steel, high speed steel, hardened steel, high frequency hardened steel, tool steel, bearing steel, etc. Typical parts include mortar wall, high-speed steel roller, hardened gear/gear shaft, bearing, ball screw, mold and so on. Using CY 1/CY6 and HJ6 series cbn tools, the effect is obvious. The blade has excellent toughness and wear resistance; The cutting ability ap of one side back can reach 7.5mm, and it can process high-hardness steel parts between HRC 45 and HRC 79.
(3) Ordinary gray cast iron (HT 150/200/250/300, etc. )
? For example, the engine block/cylinder head, brake disc, brake drum, pulley and clutch pressure plate are all gray cast iron. A series of cutters made of CY3 and HJ3 materials. The processing speed is fast, the efficiency is high, and the cost is effectively saved.
(4) Other difficult-to-process materials
? Such as powder metallurgy, high-temperature alloy materials, nickel-based, iron-based and cobalt-based high-hardness surfacing/spray welding/laser cladding/thermal spraying materials. Use HJ8 cubic boron nitride cutter.
