Turn-Mill Complex Machining

Combined turning and milling operations in a single setup for complex turned parts with milled features, holes, slots, and off-axis geometries. Our advanced turn-mill centers eliminate the need for multiple machine setups, reducing lead times and improving accuracy for parts requiring both turning and milling operations.

Understanding Turn-Mill Machining

The ultimate solution for complex turned parts requiring both turning and milling operations.

What is Turn-Mill Machining?

Turn-mill machining combines the capabilities of CNC turning and CNC milling in a single machine. These advanced machines can perform turning operations (rotating the workpiece) while simultaneously or sequentially executing milling operations (rotating the cutting tool), all in one setup.

This integrated approach enables the production of complex parts that would traditionally require multiple setups on separate machines. Turn-mill centers can create cylindrical features through turning, then add milled features such as holes, slots, flats, keyways, and off-axis geometries without repositioning the part.

Our turn-mill machines are equipped with live tooling and multiple spindles, enabling efficient production of complex components with exceptional precision and reduced lead times.

Why Choose Turn-Mill Machining?

Turn-mill machining offers unique advantages for complex turned parts.

Single Setup

Complete both turning and milling operations in one setup, eliminating multiple machine transfers and reducing setup errors.

Reduced Lead Times

Eliminate machine changeover time and part repositioning, significantly reducing overall production time.

Improved Accuracy

Single setup ensures better alignment between turned and milled features, improving dimensional accuracy.

Turn-Mill vs Standard Turning

Understanding when to choose turn-mill over standard turning.

Turn-mill machining is ideal for parts requiring both cylindrical turning and milled features such as holes, slots, keyways, flats, or off-axis geometries. It eliminates the need for multiple setups and machine transfers, making it more efficient for complex parts.

Standard turning is more cost-effective for simple cylindrical parts that don't require milling operations. Our engineers can help you determine the best approach for your project based on part complexity and production requirements.
