The optimal process for matching part features between turning and milling machining

The core logic of selection is "if simple processes can be used, there is no need for complex processes". On the premise of meeting the requirements of the drawings, priority should be given to selecting solutions with higher efficiency and lower cost.

Prioritize the scenario of turning machining

All rotational symmetrical parts: shafts, discs, sleeves, nuts, pin shafts, etc;

Precision fittings with high requirements for roundness, coaxiality, and runout;

Require high gloss appearance of non-ferrous metal parts, such as aluminum decorative surfaces and sealing mating surfaces;

Large scale production of rotary parts, pursuing ultimate processing efficiency and cost control.

Prioritize the scenario of milling machining

Non rotating flat surfaces, cavities, grooves, and irregular contour parts;

Complex surfaces, polyhedra, and multi angle hole parts;

Asymmetric structural components such as molds, fixtures, and tooling plates;

Multiple varieties, small batches, and parts with frequent structural changes can be quickly changed using the flexibility of milling.

Advanced solution: turning milling composite machining

For complex parts with both rotational characteristics and irregular structures, such as shaft components with flat surfaces and keyways, a combination of turning and milling processes can be used: a one-time clamping can complete both turning and milling processes, avoiding positioning errors caused by multiple clamping, ensuring accuracy and improving efficiency. This is the mainstream optimization solution for complex precision parts.
