CNMN120408 Solid CBN Tips high efficiency Hard Part Turning Bearing steel Wind Power Bearings 

1. Halnn Tools Solid CBN Tips high efficiency Hard Part Turning Bearing steel Wind Power Bearings 

With the continuous development and innovation of the tool industry, the company has finally developed a high-efficiency cutting tool and realized the “replacement grinding by turning” process. The “turning for grinding instead of grinding” process not only avoids grinding burns, but also mainly performs dry cutting, achieving clean production and creating a good processing environment.

Tool materials that can be used to “turn and grind instead of grinding” slewing bearings are coated, ceramic and CBN. In order to reduce the production cost, different parts need to choose different tool materials. For example, the slewing bearing with larger diameter gears is better to choose more wear-resistant ceramic tools and CBN tools.

Secondly, ceramic tools and CBN tools can be used in combination, among which ceramic tools are brittle. CBN tool hardness is second only to diamond. It is called superhard tool and can process ferrous metal above HRC45, especially in the field of hardened steel.

2. Characteristics of Solid CBN Tips 

3.Advantages of Halnn Solid CBN Tips 

Finishing wind turbine bearings must require high hardness, wear resistance and impact resistance. For the hardness and deformation of heat-treated bearings after wind treatment, Halnn Tools proposed the concept of “Cubic Boron Nitride Monolithic Polycrystalline Blade” for rough machining. With the technical strength accumulated by long-term cultivation and the most advanced technology development capability, the era can be accurately grasped. The pulse, the development of "high-speed, precision machining" turning tools, milling cutters and CNC blades. He enjoys a high reputation in the academic field of superhard tools.
