CBN inserts promotes the application and expansion of high hardness materials

share:
Introduction:Unlike common materials, high-hardness materials are difficult to process and have different processing properties. Due to the high hardness materials in the turning process, some problems often occur, such as the severe work hardening of high manganese steel during the machining process, serious casting defects during the rough turning of cast iron rolls, and many other factors that affect the selection of machining methods and tools.

CBN inserts promotes the application and expansion of high hardness materials

Unlike common materials, high-hardness materials are difficult to process and have different processing properties. Due to the high hardness materials in the turning process, some problems often occur, such as the severe work hardening of high manganese steel during the machining process, serious casting defects during the rough turning of cast iron rolls, and many other factors that affect the selection of machining methods and tools. Careful analysis is required before machining, and planning is required from the selection of the machine tool to the cutting process.

 

The size and shape of high hardness materials are different, and the processing positions are different, resulting in different machine tools, fixtures, cutting tools and cutting parameters. As far as production efficiency is concerned, the tool is the key factor. At present, the tool commonly used for cutting high-hardness and difficult-to-machine materials is a cubic boron nitride blade, which is a machine-clamped indexable tool with a hardness of about HRC 98.5 and can withstand high temperatures of 1400°C. Dry cutting reduces environmental pollution.

 

When using CBN inserts to process high-hardness and difficult-to-machine materials, the roughing and finishing processes must be processed according to different parameters. Indexable CBN inserts have high processing efficiency and are currently the first choice for roughing high hardness. Ling super-hard non-metallic adhesive legislation CBN BN-K1 grade high-hardness cast iron roll for rough turning, the effect is several times that of ceramic cutters.

 

Halnn provides the relative suitable tools and solutions for difficult-to-process materials and high-efficiency processing purpose.
