1. Halnn Tools BN-S20 Solid PCBN inserts Hard Part Turning 5CrMnMo Bearing steel Wind turbine bearing
With the development of the manufacturing industry, continuous improvement of processing efficiency is the theme of sustainable development of the machine tool and tool industry. The production efficiency of the machine tool comes from the tool. Under the premise of ensuring the quality and precision of the workpiece, advanced tools and reasonable parameters are used to improve the machining efficiency and workpiece quality. For high-hardness cast iron parts, cubic boron nitride inserts are often used, which can be processed efficiently without adding cutting fluid. At the same time, the auxiliary time such as tool change also affects the production efficiency, so the use of CBN tools can quickly improve the processing efficiency.
2.Advantages of Halnn Tools full form PCBN inserts Interrupt Cutting 42CrMo4 Bearing steel Wind turbine bearing
In recent years, Halnn Tools has provided a variety of high quality, high performance and high efficiency tool products with its long-term technical strength and cutting-edge technology development capabilities. For large slewing bearings used in the wind power industry, the hardness after heat treatment is high. Halnn Tools has developed a brand new product for the slewing bearing - BN-S200 grade cubic boron nitride tool.
For the slewing bearing with a balance of ≥ 2mm, it is suitable to select the BN-S20 grade of cubic boron nitride tool, which has high hardness and strong impact toughness.
