The cutting tools choice for heavy-duty cutting---CBN Insert
With the transformation and upgrading of metallurgical steel, energy and heavy industry, more and more high hardness difficult to process materials, such as casting high-speed steel roll, high-performance high-hardness alloy wear parts began to use with a large number applications. In order to better meet the manufacturing industry requirements, we have adopted heavy-duty cutting method to get high efficiency and Low-cost requirements.
Heavy-duty cutting is characterized by roughing process, the 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, heavy-duty cutting with cutting speed is low, cutting depth is large, and 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. Solid CBN Insert is the first choice materials for heavy cutting iron metal whose hardness is second only to diamond.
Halnn, as a pioneer in the localization of superhard tool, made CBN Inserts machining brittle hard materials for the research direction in the early times. Specific for heavy-duty cutting process, Halnn has developed a type Solid CBN Insert Grade BN-K1 for machining high hardness cast iron, and the hardness can be achieve HRC95~100, and is the most widely used for heavy turning rolls, slurry pump, and high manganese steel.
Application Case: Halnn BN-K1 Solid CBN Insert rough machining HSS
Machining Materials:HSS (ZGMn13)
Machining Site: cylindrical
Insert Model: BN-K1 SNMN1507
Cutting Data: Vc=80m/min,ap=7.5mm, Fr=0.3mm/r
Compared with traditional carbide insert:cutting speed will improve 3.2 tims, and the cutting depth will improve about 3 times, the machining efficiency will improve about 12 times.

Besides BN-K1 Solid CBN Insert, we also have another grade BN-S20 specific for heavy cutting, which is suitable for heavy turning cast steel and forged steel, especially for processing the workpiece which hardness is above HRC60. It not only improve the working efficiency and ensure the surface roughness and the size dimension at the same time.
Halnn also can offer you the whole solutions for the following area:
1.High hardness cast steel/iron, such as high chromium cast iron, white cast iron, Ni-hard cast iron, ect high hardness cast iron and HMS ect wear resistant steel.
2.High hardness Workpiece after heat treatment, such as hardened bearing steel, tool steel and mold steel, also can use interrupted turning.(the cutting depth can arrive 7.5mm, and can machine the workpiece with the hardness between HRC45~HRC79)
3.Other difficult to process materials: Superalloy, metallurgical metal and other high hardness surface workpiece.(Also can be made with customized requirements)
4.Common Gray Cast Iron and Pearlite ductile iron(The tool life will be about 10~20 times of carbide insert.)
