CNC turned parts are one of the product types that Qingdao Tuoyuan specializes in manufacturing. We operate our own factory, enabling us to offer OEM services and direct-from-factory pricing. You are welcome to submit your own designs for custom orders; we will develop a tailored solution for each specific project while strictly controlling the quality of the finished products.
Machining Principle
During the CNC turning process, programmed controls ensure the precise and repeatable execution of every operation:
Workpiece Movement: The metal material is clamped by a chuck and rotates at high speed, constituting the primary motion.
Tool Movement: The turning tool is mounted on a turret and moves along a path defined by a computer program—either axially or radially relative to the workpiece—to perform the feed motion and remove excess material.
Due to this specific machining principle, this method is particularly well-suited for manufacturing parts with circular, cylindrical, or conical geometries.

Which Material Should You Choose for Turned Parts?
Selecting the appropriate material for machining is crucial. As a professional manufacturer, Tuoyuan provides expert recommendations and collaborates with you to formulate a comprehensive plan prior to production. The primary material types we offer for selection include:
1. Steel
Steel is the most widely used structural material, characterized by high strength, low cost, and excellent overall mechanical properties. Low-carbon steel exhibits high ductility and is easy to machine, while medium-carbon steel offers superior strength and toughness after heat treatment (quenching and tempering).
Typical Applications: Shafts, gears, bolts, and structural components.
2. Stainless Steel (e.g., 304, 316)
Stainless steel boasts excellent corrosion resistance and an aesthetically pleasing surface finish. However, its high toughness and poor thermal conductivity during machining necessitate the use of specialized cutting tools and robust cooling systems—challenges that Tuoyuan is fully equipped to handle.
Typical Applications: Medical instruments, food processing equipment, chemical valves, and marine components.
3. Aluminum Alloys
Aluminum alloys are the preferred choice for lightweight designs, offering low weight, high strength-to-weight ratio, excellent thermal conductivity, and corrosion resistance.
Typical Applications: Aerospace structural components, automotive parts, electronic enclosures, and heat sinks.
4. Copper and Copper Alloys
Copper alloys feature excellent electrical and thermal conductivity, high wear resistance, and an attractive appearance.
Typical Applications: Plumbing fittings, valves, electrical connectors, and decorative components.
