What is Mill Turning?

Mill-Turning seamlessly integrates milling and turning operations, streamlining manufacturing processes. This advanced CNC machining technique eliminates the need for multiple setups, boosting efficiency. Simultaneous turning and milling, along with the ability to handle intricate geometries, make Mill-Turning a practical choice for precision manufacturing.

As a workpiece rotates, the Mill-Turn machine executes rotating tooling operations such as cross-drilling, tapping, slotting, and milling simultaneously. This eliminates the need for multiple setups and reduces downtime associated with changing between different machining centers. This innovative approach not only accelerates part production but also maintains high accuracy, making Mill-Turning an incredible option for precision manufacturing at Owens Industries.

Benefits of Multi-Axis Mill-Turn Machining

Mill-turn machining stands out as a revolutionary process that combines turning and milling operations into a single, highly efficient workflow.

  • Single-Setup Efficiency: Mill-turn technology completes complex parts in a single setup, reducing the need for multiple machines and minimizing errors. Its true multitasking capability, turning workpieces while simultaneously executing rotating tooling operations, leads to faster production and reduced setup times.
  • Swift Production: Mill-turn machines facilitate rapid transitions from concept to final product, ensuring faster time-to-market and reduced lead times. Mill-turn technology also allows for early optimization of part designs, ensuring efficiency and cost-effectiveness in the machining process.
  • Enhanced Precision: Integrating turning and milling minimizes repositioning, leading to improved accuracy with tight tolerances as fine as +/- .0001. Mill-turn machining excels in the creation of intricate part geometries, offering a solution for components with complex shapes and features.
  • Material Versatility: Capable of handling a wide range of materials, from common metals to superalloys, making it suitable for diverse industries.

Mill Turning vs Milling and Turning

Milling and turning are individual CNC machining processes, each with its unique characteristics and applications. However, the combination of these processes in mill-turn machining introduces an approach that offers advantages over separate milling and turning operations. Mill turning is characterized by its integration of milling and turning capabilities within a single-machine setup. This process efficiently handles complex parts by simultaneously performing milling and turning operations.

When milling and turning are executed separately, the machining operations are divided between dedicated machines. Milling involves a rotating cutting tool removing material while turning centers around a rotating workpiece with a stationary cutting tool. While effective for specific operations, this approach may necessitate transferring workpieces between machines, leading to increased setup and handling times. In CNC lathe machining and turning, the workpiece is held in place by a chuck and rotated at high speeds while the cutting tools are brought into contact with the workpiece to remove material and create the desired shape.

The choice between mill turning and separate milling and turning processes depends on the project's requirements. Mill turning stands out for its efficiency in handling complex parts, minimizing setup times, and offering a consolidated approach to machining operations.
