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.
