Turning instead of Grinding Hardened Steel Bearings with CCGW09T308-2S Brazing CBN Turning Tools

1. CBN Turning Tools Hardened Steel Bearing

Hard turning bearing advantages:

(1) The metal removal rate for turning is usually 3-4 times that of grinding, which greatly improves production efficiency.

(2) Tool change during hard turning can be completed within 2 minutes, avoiding the loss of production time.

(3) Most of the heat produced during the hard turning process is taken away by the chips, which has excellent surface quality and precise roundness to ensure the accuracy of the machined surface.

(4) Dry cutting is often used for hard turning bearings, which is clean production, reduces production costs, and the chips that are turned off are easy to recycle.

2. Why we Choose Halnn Tools CBN Turning Tools Hardened Steel Bearing

At present, the tool materials in the processing market are cemented carbide tools, ceramic tools and cubic boron nitride blades. Wind power bearings are large forgings. It is inevitable that deformation will occur after heat treatment, and the balance will be uneven. Therefore, it is not recommended to use ceramic tools. The cubic boron nitride insert is currently the best tool material for processing hardened steel materials. In particular, the non-metallic binder cubic boron nitride inserts BN-S20 grade and BN-S200 grade developed by Halnn Tools have a good effect on processing wind power bearings.

Halnn Tools non-metallic binders Cubic boron nitride inserts BN-S20 grades and BN-S200 grades are all Solid CBN inserts, of which BN-S200 grades are mainly used for finishing operations, and the depth of the knife is controlled at 0.5mm. Within. The BN-S20 grade can be used for rough finishing. It is mainly used for wind power bearings with a margin of >2mm or more. It can be processed by one knife, saving processing time and improving processing efficiency.
