Applicazione Background
The core challenge in interrupted rough machining of hardened steel parts (HRC58-62) lies in: while bearing high cutting force generated by high-hardness material, the cutting edge of the tool is repeatedly subjected to combined mechanical and thermal shocks. This makes it far more difficult than continuous turning. Especially in the current market with fierce competition and strict cost control, controlling tool life and tool cost is a common issue for both component manufacturers and tool suppliers.
As an enterprise engaged in the R&D and manufacturing of superhard cutting tools, Worldia expands its PCBN and PCD MANANOVA series products based on market demands. This helps customers broaden the application scope of cutting tools and effectively control tool costs.
Analisi della soluzione
◎ The workpiece in this case is a hardened steel gear of HRC58-62. Four symmetrical end grooves on the machining surface create interrupted cutting conditions. The process is rough turning of the inner bore and end face for full-line mass production, and the customer has a requirement for extended tool life. Without modifying cutting parameters, the Worldia solution adopts brand-new MANANOVA coated PCBN inserts and delivers a 53% increase in tool life.
◎ This case covers interrupted rough turning. The cutting edge undergoes alternating severe mechanical and thermal shocks when entering and exiting cuts. The Worldia solution adopts MHN20C Insert Grade with balanced wear resistance and toughness, paired with a standard reinforced cutting edge. The C3 coating further enhances the cutting edge’s wear resistance and high-temperature resistance.
◎ Worldia’s upgraded MANANOVA series superhard cutting tools cater to fierce and volatile market demands. They provide a cost-effective, quick-response tool replacement solution for customers, helping extend tool life, reduce tool changeovers, boost production efficiency and control tool costs.
