Turning Machined Parts
- Wide Material Range: Carbon steel, alloy construction steel, stainless steel, alloy tool steel, and other special materials available.
- Complex Geometries: Capable of producing steps, tapers, grooves, threads, and contoured profiles on rotational parts.
- Process Flexibility: Rough, semi-finish, and finish turning can be combined with drilling, boring, threading, and grooving.
- Stable Quality: Controlled rough and finish operations minimize residual stress and deformation.
