Turning-Milling Compound Machine: Integrated Machining for Complex Parts in a Single Setup
What is a Turning-Milling Compound Machine?
A Turning-Milling Compound Machine (Mill-Turn Center) combines CNC turning and 5-axis milling capabilities to machine complex geometries without reclamping. It features live tooling, Y-axis, and B-axis spindles for simultaneous operations.
Types & Configurations
| Model Type | Key Features | Work Envelope |
|---|---|---|
| Vertical Mill-Turn | Gravity-assisted chip fall | Ø800 mm × 1,000 mm |
| Horizontal Mill-Turn | Bar feeder integration | Ø150 mm × 500 mm |
| Multi-Tasking | Twin turrets + sub-spindle | Ø300 mm × 750 mm |
Key Benefits
✔ Single Setup Machining: Eliminates alignment errors.
✔ Cycle Time Reduction: Completes parts 60% faster than separate machines.
✔ Geometric Freedom: Machines undercuts, off-center holes, and 3D contours.
✔ Material Savings: Near-net-shape processing cuts waste by 30%.
Applications
- Energy: Valve bodies with angled ports.
- Defense: Missile guidance housings.
- Medical: Asymmetric orthopedic implants.
Operation Process
- Stock Loading: Robot or bar feeder loads material.
- Turning Phase:
- Main spindle rotates at 4,000 RPM for OD/ID turning.
- Milling Phase:
- Live tools (12,000 RPM) mill flats, drill cross-holes.
- Backworking: Sub-spindle machines rear features.
- Automated Unloading: Parts sorted via conveyor.
