Application Background
■ The main challenge in mass production of high-precision hardened steel parts is to maintain superior geometric accuracy, surface finish, dimensional consistency and stability under post-quenching hard conditions. It involves not only material, process and efficiency issues, but also a comprehensive test of cutting tool performance, machine rigidity and thermal control.
■ Taking the finishing turning of inner raceway on bearing seat ring as an example below, Worldia custom tools effectively extend tool life and reduce tool change downtime, delivering an efficient, stable and durable machining solution for customers.
Solution Analysis
◎ In this case of finishing turning the inner raceway of bearing seat ring, the customer required longer tool life and fewer tool changes. Based on the characteristics of finishing processes, Worldia’s custom PCBN hard turning solution delivers a 24% longer tool life than the original solution under identical cutting parameters.
◎ Matched to the workpiece stock removal and actual machining process characteristics, Worldia adopts high-wear-resistance PNH0117 grade with customized edge geometry optimized for working conditions. The C3 coating on inserts improves lubricity and anti-wear performance.
◎ Worldia custom superhard cutting tools can extend tool life, reduce tool change frequency and boost productivity for common difficult-to-machine materials, whether for heavy-stock roughing or high-quality finishing, solving critical machining challenges for customers.
