The cutting tools materials for heavy-duty turning
With the transformation and upgrading of metallurgical steel, energy and heavy industry, there are more and more difficult to process materials, such as casting high-speed steel roll, high-performance high-hardness alloy wear parts. In order to better meet the manufacturing efficiency Low-cost requirements, have adopted heavy-duty turning method.
Heavy-duty turning is characterized by rough processing, processing margin is large and uneven, and rough surface has hard spots, sand, porosity and other defects. And the workpiece size of heavy-duty cutting is generally large, heavy weight, therefore, the cutting speed is low, the cutting depth is large, the feed rate is low.
To achieve heavy cutting, the tool material is very important. At present, CBN Insert is the hardest tool for processing ferrous metal material. The solid cbn insert is the first choice for cutting iron metal, which hardness is second only to diamond.
Halnn Superhard, as the predecessor of Chinese superhard cutting tools, have researched brittle hard materials in early times. Specific for heavy-duty turning high hardness cast iron, Halnn launched BN-K1, which hardness is about HRC95~100, and make it possible of machining hardness materials with China CBN Insert. BN-K1 have been widely used for machining rolls, pump and high manganese steel parts in current times.
For example: BN-K1 rough machining Mortar wall
Workpiece Materials: High Manganese Steel
Machine Part:Cylinder
Insert Model:BN-K1 SNMN1507
Cutting Data:Vc=80m/min, ap=7.5mm, Fr=0.3mm/r

Besides BN-K1 solid cbn insert, it also has another solid cbn insert grade BN-S20 which is suit for machining cast steel and forged steel, which will also make sure the roughness and the dimension.
