PCBN Automotive Production
Automotive Component Machining
For brake discs, brake drums, cylinder liners, and engine blocks where production speed, stable tool life, and cost per part drive the tooling decision.
Typical machining challenges
- Dry or wet cast iron machining at high line speed.
- Stable insert life across repeated production runs.
- Lower tooling cost per part on brake component lines.
- Finishing quality and output improvement without excessive insert changes.
Recommended solution overview
HEYI HP-S300 is relevant for high-speed cast iron production jobs where steady tool life and efficiency matter. HEYI HPK30 fits high-speed finishing and similar applications where stable surface result and output are both required.
