Bi-metal machining process
CoroMill® Century – Bi-metal machining process without burring, chipping, or scratching
Many modern engines use cylinder blocks that consist of gray cast iron liners casted together with aluminum. This makes machining engine block deck faces a considerable challenge.
Sandvik Coromant has developed a process in which bi-metal cylinder blocks can be machined without burring, chipping, or scratching using CoroMill® Century.
Features and benefits
- Reliability and surface quality according to the component specification demands
- Typical surface finish achieved Rz 2.12–3.86 / Rt 2.52–4.43
- Depending on the application, the process can be done in 1 or 2 machining steps
- Smallest cutter diameter always in correlation with the outer and inner diameter of the cylinder liner
- Standard wiper insert CB50
- MQL application
Application
- Bi-metal machining method (aluminum cast iron) on fire face, deck face, top face cylinder blocks in standard machine center (M/C)
