CNC Turning
Focus on high-speed precision turning of high-precision rotational parts (shafts, rods, bushings, sleeves, etc.), ensuring excellent dimensional accuracy, roundness and surface finish.
What exactly is CNC turning? What are the differences between CNC turning and CNC milling?
expand_less expand_more-
CNC turning is a precision machining process that performs cutting through workpiece rotation and fixed cutting tools. It is mainly used for manufacturing cylindrical or rotationally symmetric parts, such as shafts, screws, bushings, etc.
The core difference lies in the motion mode:
CNC Turning: The workpiece rotates while the cutting tool moves. It is similar to pottery making on a pottery wheel, where the raw material rotates and is shaped by tools.
CNC Milling: The cutting tool rotates while the workpiece moves. It is similar to carving, where a rotating carving knife moves in different directions for sculpting.
Simply put, turning excels at making "round" parts, while milling is good at making "square" parts or those with complex contours.
What experience do you have in turning high-hardness or special materials?
expand_less expand_more-
We are proficient in processing various difficult-to-machine materials with mature technologies:
Difficult-to-machine metals: Titanium alloys (such as TC4), precipitation-hardening stainless steels (such as 17 - 4PH), high-strength alloy steels.
Commonly used metals: Various stainless steels, aluminum alloys, copper alloys.
Non-metallic materials: PEEK, Delrin (POM), machinable ceramic blanks, etc.
We have a dedicated tool library and cutting parameter database for different materials, which can effectively ensure processing efficiency, surface quality and control tool costs.
In addition to conventional turning, can you process more complex parts?
expand_less expand_more-
Yes. For parts with structures beyond conventional ones, we provide advanced solutions:
Turn-Mill Compound Machining: Capable of completing multiple processes in one go, including external turning, face milling, groove milling, inclined hole drilling, tapping, etc., avoiding errors caused by multiple clamping operations.
Multi-Axis Linkage Turning: Used for processing rotating parts with complex curved surfaces (such as elliptical and parabolic contours).
Processing of Slender Shafts and Thin-Walled Parts: Equipped with specialized tooling fixtures and cutting processes to effectively control part deformation and ensure dimensional accuracy.
How to ensure the quality stability and traceability of turned parts?
expand_less expand_more-
We provide double guarantees through both systems and hardware:
Whole-Process Quality Control: Achieving full-process monitoring from incoming raw material inspection, first article inspection, in-process patrol inspection to final inspection.
Precision Testing Equipment: Equipped with high-precision roundness testers, roughness testers, and coordinate measuring machines with scanning functions to conduct 100% inspection of key dimensions.
Comprehensive Traceability System: Each batch of parts has corresponding production process cards and inspection reports filed, ensuring data traceability and meeting industry audit requirements.
What is "turn-mill compound" machining? What advantages does it have over traditional turning?
expand_less expand_more-
Turn-mill compound machining is an advanced machining center integrating turning and milling functions.
Its core advantage is "one-time clamping, complete all processes":
Traditional Turning: Only capable of completing rotation-related processes such as external turning, drilling, and tapping. If a part has side holes or special-shaped features, it needs to be clamped to a milling machine for secondary processing, which is time-consuming and may cause errors.
Turn-Mill Compound Machining: After one-time clamping of the workpiece, multiple processes such as turning, milling, drilling, tapping, and grooving can be completed. This greatly improves processing efficiency and the overall precision of parts, avoiding errors caused by multiple clamping operations.
What about production capacity and response speed for urgent prototype projects or mass production orders?
expand_less expand_more-
