Heavy Interrupt Cutting Hardened Steel Wind Power Bearings with Halnn supplier CBN Inserts

1. Halnn Tools CBN Inserts Heavy Interrupt Cutting Hardened Steel Wind Power Bearings

With the development of science and technology, the precision requirements for the processing of extra large bearings are getting higher and higher. Due to the limitation of the machining precision of the general CNC vertical lathe, the reaming reamer of the grinding process has a longer grinding time and lower efficiency. With the development and application of superhard tools (CBN tools), in many cold machining, grinding can be replaced by turning.

CBN tool features for hard-turned bearing:

(1) CBN cutters have high hardness and wear resistance and are the second highest hardness materials known at present. When processing high hardness materials, dimensional deviation and dimensional dispersion in processing of large parts can be reduced.

(2) CBN tools have high thermal stability and high temperature hardness. When the cutting temperature is high, it is beneficial to the cutting process, but has little effect on the tool life.

3. Advantages of Halnn Tools CBN Inserts

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.

4.Application Case

BN-S200 Solid CBN Insert processing bearings
Machining Part:Slewing bearing ring
Workpiece Hardness:HRC 47~55
Cutting Type:Dry Cutting
Machining Materials:42CrMo
Inserts Grade:BN-S20
Cutting Parameters: Vc=90-150m/min，ap=1-4mm，Fr=0.05-0.35mm。
Comparison with the grinding process: In terms of time: all the grinding process is more than 18 hours, and the use of Valin super hard BN-S20 CBN tool takes only 4.5 hours. In terms of tool durability: BN-S20 grade CBN tool can finish turning more than 30 sets of ferrules; material consumables only have 1/5 of grinding; the tool has high durability and lower cost of use.
