What Is Precision CNC Turning?
CNC turning is a precision subtractive machining process that uses computer-controlled lathes to shape rotating workpieces with stationary cutting tools. It is specialised in producing accurate, smooth, axisymmetric rotational components with consistent dimensional stability. Ideal for cylindrical, round, threaded and concentric parts, CNC turning supports rapid prototyping and mass production for low to high-volume industrial applications.

CNC Turning Surface Treatment Processes
We provide a full range of professional surface treatment services for CNC turned parts, optimizing surface hardness, corrosion resistance, aesthetics and wear resistance. All finishing processes are customized to meet industrial assembly and outdoor service requirements for precision turning components.
Anodizing
Electrochemical oxidation forms a dense protective oxide film on aluminum turning parts. It improves surface hardness, abrasion resistance and corrosion resistance, while providing diverse color options for decorative and anti-oxidation purposes.
Sandblasting
High-pressure sand impact treatment creates a uniform matte textured surface on turned components. It removes tool marks and burrs, improves surface uniformity, and enhances coating adhesion for subsequent finishing processes.
Electroplating (Nickel/Chrome/Zinc Plating)
Metal plating treatment deposits a uniform metal coating on steel, copper and alloy turning parts. It effectively prevents rust and oxidation, improves surface smoothness and wear resistance, and upgrades overall part durability.
Polishing
Precision mechanical polishing removes turning tool traces, burrs and surface flaws. It achieves a smooth, glossy mirror or matte surface, improving the appearance quality and assembly fit of precision rotary parts.
Passivation
Chemical passivation treatment for stainless steel turning parts forms an inert protective film on the surface. It eliminates surface free iron, greatly improves rust and corrosion resistance, and does not change part size or surface texture.
Black Oxide Finishing
Blackening treatment for carbon steel and alloy steel turning components. It provides anti-rust and lubrication performance, reduces light reflection, and delivers a uniform industrial black appearance for mechanical structural parts.

Frequently Asked Questions
Here you can find answers to frequently asked questions about custom CNC & EDM machining, material options, tolerances, quotation and delivery. Our team is ready to assist with any extra concerns.
Our Precision CNC Turning Services support CNC turning, drilling, boring, threading, grooving, and other secondary turning operations. Live tooling and multi-axis capabilities can be used for components requiring multiple features in a single setup, improving accuracy and process efficiency.
We can turn aluminum, stainless steel, carbon and alloy steels, brass, copper, titanium, engineering plastics, and other machinable materials. Tooling, cutting parameters, and coolant strategies are selected according to the material and component requirements.
Precision CNC turning can achieve tight dimensional and geometric tolerances for suitable components. Actual capability depends on material, diameter, length-to-diameter ratio, geometry, machine configuration, and inspection requirements. Critical dimensions and GD&T are evaluated from the engineering drawing.
We manufacture shafts, pins, bushings, sleeves, threaded components, fittings, precision inserts, and other rotational parts. Complex turned parts can also incorporate drilling, milling, threading, and other secondary features.
Yes. We support prototypes, low-volume batches, and high-volume production. CNC programming, tooling, workholding, and inspection procedures can be optimized for repeatability, cycle efficiency, and consistent quality.
Depending on the application, parts can receive anodizing, plating, passivation, polishing, grinding, bead blasting, deburring, and other specified surface treatments. Finishing processes can be coordinated to maintain critical dimensions and functional surfaces.
MOQ and lead time depend on material, part complexity, quantity, tolerance requirements, tooling, finishing, and inspection specifications. Prototype quantities and recurring production programs are both supported, with delivery schedules confirmed after technical review.
Provide your 2D drawing or 3D CAD model, material grade, quantity, critical dimensions and tolerances, surface-finish requirements, and GD&T specifications. Our engineering team can review manufacturability and recommend the appropriate turning process and production strategy.
