Hard Machining Wind Power Bearings with TNMN CBN Cutting Tool have large allowance
1. Halnn Tools Hard Machining Wind Power Bearings with SNMN CBN Cutting Tool have large allowance
After the heat treatment of large bearings, the remaining amount is large, and the solid polycrystalline CBN tool can improve the production efficiency. The BN-S20 grade is a CBN material that is widely used at present. BN-S20 grade belongs to the solid polycrystalline CBN cutter, the hardness reaches between HRC95-HRC100, and contains ceramic bond to ensure higher chemical resistance at high temperature and better wear resistance.
For example, the inner and outer rings of wind power bearings are processed: the production efficiency is 4 times that of the grinding process, but the material consumables are only 1/5 of the grinding; Halnn Tools tools are durable and more affordable.
