A：Shaft-type parts (most common): drive shafts, motor shafts, valve cores, stepped shafts, linear shafts, threaded shafts
Bushing / sleeve-type parts (hollow rotational parts): bearing sleeves, bushings, tubes, cylinder sleeves, nuts (with internal thread), hollow pipe fittings
Also suitable for disc / flange parts, threaded parts (internal & external threads), and complex curved turning components.
The core advantage of CNC turning lies in high-precision and high-efficiency machining of rotationally symmetric parts, especially for batch production where dimensional consistency and surface finish are critical.
For non-rotational or asymmetric parts — such as square, polygonal, irregular surfaces or parts with complex/deep cavities — CNC turn-mill machining is recommended to achieve integrated and efficient manufacturing.
A: Machining Principle:
CNC turning involves a rotating workpiece with a stationary cutting tool, ideal for producing rotationally symmetric parts (shafts, sleeves, discs).
CNC milling uses a rotating cutting tool while the workpiece moves, focusing on non-rotational or complex geometry parts (housings, brackets, irregular shapes).
Machining Targets:
CNC Turning: cylindrical parts with round cross-sections (e.g. motor shafts, bearing sleeves).
CNC Milling: flat surfaces, slots, holes, and curved features (e.g. machine brackets, gearbox housings).
A：Yes, we are fully capable of producing plastic turned parts. Common plastics processed on our CNC lathes include ABS, polycarbonate, PTFE (Teflon), nylon, and POM.
5-Axis CNC Machining Services simplify complex part production by reducing setups, improving accuracy, and enabling efficient machining of difficult geometries.
