What is CNC Turning?

CNC turning is a precision machining process where a cutting tool removes material from a rotating workpiece to create cylindrical or round-shaped parts. It is widely used for producing shafts, pins, bushings, connectors, and other symmetrical components.

Compared with manual turning, CNC turning ensures higher consistency, tighter dimensional control, and faster production efficiency, making it ideal for both prototypes and batch production.

Quality Control

We follow strict quality control procedures throughout the manufacturing process to ensure every part meets customer specifications. From material inspection and in-process checks to final verification, each component is carefully inspected for dimensional accuracy and surface quality.
Hardness Test scaled

Hardness Test

Hardness test can be divided into Brinell hardness, Vickers hardness, Rockwell hardness, micro Vickers hardness, etc. Rockwell hardness test is the most commonly used test method, and the hardness value is determined by the depth of indentation plastic deformation. Hardness testing can be used to verify the surface and core hardness of the workpiece, mainly used in metal materials.Surface hardness is the resistance of the surface to deformation or damage, and the core hardness can reflect the essential properties of the material.
Coating Thickness Testing1 scaled

Coating Thickness Testing

Coating Thickness Testing is the process of measuring the thickness of a coating layer applied to a material's surface, typically to ensure that it meets specific standards for quality, durability, and performance. This testing is crucial in many industries, including automotive, aerospace, electronics, and construction, as it helps confirm that coatings—such as paint, anodizing, plating, or galvanizing—are applied evenly and meet required specifications.
Film Thickness Test1 scaled

Film Thickness Test

Film thickness test is a kind of method to measure the thickness of non-magnetic coatings (such as aluminum, chromium, copper, enamel, rubber, paint, etc.) on magnetic basis metal (such as steel, iron, alloys, and hard magnetic steel). It can also measure the thickness of non-conductive coatings (such as enamel, rubber, paint, plastic, etc.) on non-magnetic basis metal(such as copper, aluminum, zinc, tin, etc.).Our test method has the characteristics of small measurement error, high reliability and good stability, which can control and ensure the quality of products.
CMM Testing scaled

CMM Testing

High-precision 3D measurement using a Coordinate Measuring Machine to verify dimensional accuracy and GD&T requirements, ensuring every part meets the exact design specifications.
Surface Roughness Test scaled

Surface Roughness Test

The stylus method is a technique used to measure the surface roughness of the workpiece,which is suitable for the test range of R0.02-5μm,It has the characteristics of high precision, wide measuring range and simple operation. It is widely used in the inspection of various metal and non-metal processing surfaces.
Projector Test

Projector Test

Projector is used to measure hardware dimensions include position, concentricity, straightness, profile, roundness and the size related to the GD&T,such as diameter, radius, length, Angle, width, height, depth, point-to-point distance, point-to-line distance, circle distance, and so on.
Salt Spray Test

Salt Spray Test

Salt spray test is divided into neutral salt spray test, acetate spray test, copper salt accelerated acetate spray test, alternating salt spray test. Neutral salt spray test is widely used in various industries.By accelerating corrosion of metal protective layer,which makes it lose decorative and reduce the mechanical strength, the purpose is to assess the product or metal material salt spray corrosion resistance quality.

CNC Milling Machining FAQs

A: CNC turning is used to manufacture cylindrical precision parts such as shafts, bushings, connectors, and threaded components.

A: CNC turning rotates the workpiece while the cutting tool remains stationary. It is best suited for cylindrical and rotational parts. CNC milling uses rotating cutting tools to machine complex flat or three-dimensional geometries.

A: We machine a wide range of materials, including aluminum, stainless steel, titanium, brass, copper, carbon steel, POM, PTFE, nylon, and other engineering plastics.

A: Standard machining tolerances are typically ±0.02 mm, while critical features can be machined to tighter tolerances depending on part geometry, material, and application requirements.

A: Depending on the material and application, CNC turned parts can be supplied with as-machined finishes or additional treatments such as anodizing, plating, polishing, sandblasting, and powder coating.

A: Yes. We specialize in prototype machining and low-volume production, helping customers validate designs, reduce development time, and accelerate product launches.
