Solid CBN Turning Insert high efficiency Hard Turning Bearings with Halnn BN - S20 Inserts
1. Halnn Tools Solid CBN Turning Insert high efficiency Hard Turning Bearings with Halnn BN - S20 Inserts
When machining large scale bearings and high precision bearings, hard turning (turning instead of grinding) is a trend, the process efficiency is high and the cost is low. Traditional cutting tools carbide insert and ceramic cutters can’t satisfy their requirements.
With the widely used of the superhard cutting tools, turning instead of grinding already become a reality. As the leader of supehard cutting tools in China, Halnn Tools has special cutting tools for hard turning bearings, not only realize stable cutting performance, ensure the roughness, but also help the bearings industry reduce the total costs.
