What is Turning-Milling Compound?

• Turning: The workpiece rotates while the cutting tool moves along axial or radial directions. This is primarily used for cylindrical surfaces, holes, threads, and shaft-type components.

• Milling: The cutting tool rotates while moving along linear or curved paths, used to machine flat surfaces, grooves, keyways, and complex contours.

• Compound: Turning and milling operations are integrated on the same machine, allowing sequential or simultaneous processing of both operations without repeated setups.

Turning-Milling Compound Processing

Pinzhihao Precision offers turning-milling compound processing, combining turning and milling in a single setup for complex automotive, aerospace, and medical components.

Turning-Milling Compound Processing (also known as turn-mill machining or multi-tasking machining) is a manufacturing process that combines turning and milling operations on a single machine. This method allows components that normally require multiple machines to be machined in one setup, improving both efficiency and precision.

When to Choose Turning-Milling Compound

• Components with complex geometry that require both cylindrical and non-cylindrical surface machining.

• Parts that require multi-face or multi-hole processing, which would otherwise need multiple machine setups.

• Projects with high precision requirements to avoid errors from repeated setups.

• Batch production or small-batch high-precision custom components where efficiency and consistency are critical.
