The customer wanted to replace the two grades of alloy inserts with CBN blades, and then plated a layer of ceramic coating to process aerospace parts such as nickel-based alloys.
▶CBN inserts are generally good at machining ferrous metals, hardened workpieces like cast iron and hard steel.
▶Because the nickel-based alloy material is relatively sticky, the hardness is not high. In theory, it is not the processing range of CBN inserts.
▶The CBN inserts for processing such materials are not standard inserts, and generally have chip flutes on the inserts.
▶This kind of workpiece will not break the iron chips during processing, and the chip removal problem cannot be solved with conventional inserts.
●CBN and PCD such as nickel-based superalloy, titanium alloy, stainless steel (white iron 316) are not suitable, they will stick to the knife and collapse. If you need to use CBN inserts
, you need to coat the inserts. Among them, titanium alloys can be finished with PCD inserts
, and MORESUPERHARD also has successful cases.
