Hard Turning Bearing PCBN Inserts Cbn Cutting Tools With BN - H11 Grade

Hard Turning Bearing steel Wind Power Bearings with BN-H11 Grade PCBN Cutting Tool

1. Halnn Tools Hard Turning Bearing steel Wind Power Bearings with BN-H11 Grade PCBN Cutting Tool

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.
