Welded CBN inserts and Tipped PCBN inserts have the advantages of high hardness, good wear resistance, and strong thermal stability when processing hardened steel, which can effectively improve processing efficency and quality.
Characteristics of brazed PCBN inserts: Advantages: Double cutting edge (compared to composite sheet), suitable for semi-finishing and finishing, with a Ra ≤0.8. Secondly, it is cost-effective, with the same cutting edge, welded PCBN inserts is more economical.
Characteristics of Tipped PCBN inserts: It is a high-performance product suitable for finishing. When Ra≥0.8, tipped PCBN inserts is the best choice.
Typical components made of hardened steel: gears, bearings, ball screw, transimmission shaft and so on.
For processing hardened steel, SCBN is committed to customizing the most suitable solution for each customer through continuous research and development, and has received unanimous praise from customers.
