±0.01 mm tolerance may be achievable for suitable features and part configurations, but it should not be treated as a universal tolerance for every CNC machined component.

Achievable accuracy depends on factors such as material, component dimensions, thermal stability, machine condition, tool wear, workholding, machining strategy and inspection method.

For this reason, our quotations should be based on the actual drawing rather than a general tolerance claim.

If a dimension is functionally critical, we recommend specifying the tolerance directly on the drawing. Our engineering team can then evaluate the feature and determine an appropriate machining and inspection approach.

The achievable tolerance depends on the material, part size, geometry, machining process and specific feature.

It would be misleading to quote one universal tolerance for every CNC machined component. A small aluminum component with straightforward geometry may achieve a different tolerance from a large 316L stainless steel component with deep cavities or thin walls.

For precision components, we review critical dimensions individually and determine the appropriate machining process and inspection method.

If your drawing contains tight tolerances, please identify the critical features clearly. We can evaluate manufacturability during the quotation stage and advise whether the requested tolerance is practical for the selected material and geometry.

Yes. We manufacture custom CNC machined components from engineering plastics including PEEK, PEEK GF30, POM, PTFE, nylon, PEI and PVC.

Machining plastics requires different considerations from machining metals. Thermal expansion, material flexibility, clamping force, chip evacuation and tool geometry can affect dimensional accuracy.

PEEK GF30, for example, contains approximately 30% glass fiber and behaves differently during machining compared with unfilled PEEK.

For plastic components with tight tolerances, the drawing should identify the required material grade, dimensional requirements and operating temperature so that machining and inspection conditions can be properly considered.

Yes. RuiXing MFG has CNC machining capabilities for difficult-to-machine materials including titanium alloys and superalloys.

These materials require more careful process control than conventional aluminum or mild steels. Tool wear, cutting heat, workholding, chip evacuation and machining parameters can significantly affect both tool life and part quality.

Our CNC equipment and process capabilities have been expanded to support precision machining of titanium, superalloys and other demanding materials.

For these projects, we evaluate the material grade, component geometry, tolerances, quantity and critical features before determining the appropriate machining process.

Yes. 316L is one of the stainless steel grades suitable for our CNC machining services.

316L is commonly selected for applications requiring good corrosion resistance and compatibility with demanding environments. However, it is more difficult to machine than many aluminum alloys because of its toughness, work-hardening characteristics and thermal behavior during cutting.

When machining 316L, tool selection, cutting parameters, workholding, coolant management and tool condition can all affect dimensional stability and surface finish.

For precision 316L components, we recommend identifying critical dimensions, threads, holes, surface roughness and surface treatment requirements clearly on the drawing so that the manufacturing and inspection processes can be planned accordingly.

We manufacture CNC machined components from a wide range of metals and engineering plastics.

Common materials include:

- Aluminum alloys such as 6061
- Stainless steels including 316L
- Brass
- Titanium alloys
- Superalloys
- PEEK
- PEEK GF30
- POM
- PTFE
- Nylon
- PEI
- PVC
Other engineering plastics and metals according to customer requirements

Material selection depends on the mechanical, thermal, chemical, electrical and environmental requirements of the application.

If you are unsure which material is appropriate, provide the application conditions and technical requirements. Our engineers can help identify potential material options before production.

There is no universal MOQ for all CNC machined parts.

We can manufacture individual prototypes and samples as well as larger production batches. The economical quantity depends on factors such as material cost, programming, tooling, setup time, machining time, inspection requirements and surface finishing.

For a one-piece prototype, the unit price may be higher because engineering, programming and setup costs are distributed over only one component. For repeat production, these costs can be distributed across a larger quantity.

If you only need one or a few parts for testing, we can still review the project and provide a quotation based on the actual requirements.

Yes. We support prototype, low-volume and batch production.

The manufacturing approach for a prototype and a production order is generally similar, but production quantities allow additional process optimization. For larger batches, we can optimize tool selection, machining parameters, workholding, inspection methods and production sequences to improve efficiency and consistency.

Production capacity depends heavily on part size, complexity, material and quantity. A small and relatively simple component may be suitable for high-volume production, while a large or highly complex component may require substantially more machining time.

For this reason, we evaluate the actual drawing and quantity before confirming production capacity and lead time.

5-axis CNC machining is particularly useful for components with complex three-dimensional surfaces, multiple angled features, deep cavities or geometries that are difficult to access using conventional 3-axis machining.

A major advantage is the ability to machine multiple surfaces or features with fewer setups. This can reduce setup-related errors and improve positional relationships between critical features.

However, 5-axis machining is not automatically better for every component. For relatively simple parts, 3-axis or 4-axis machining may provide a more economical solution.

At RuiXing MFG, the machining process is selected according to the geometry and functional requirements of the component rather than using 5-axis machining simply as a marketing specification.

CNC milling and CNC turning use different cutting methods and are suitable for different part geometries.

CNC turning is primarily used for rotational components such as shafts, pins, bushings, threaded components and cylindrical housings. The workpiece rotates while cutting tools remove material.

CNC milling is generally used for prismatic or irregularly shaped components. The cutting tool rotates and moves along multiple axes to create pockets, slots, holes, contours and other features.

Some components require both turning and milling operations. For these parts, mill-turn or combined machining can reduce the number of setups and improve positional accuracy between features.

The most appropriate process depends on the geometry, tolerances, quantity and material of the component.

Yes. We manufacture non-standard and custom CNC machined components according to customer drawings, 3D CAD models and technical specifications.

Customers can provide common engineering drawing and CAD formats. The drawing should ideally include material grade, critical dimensions, tolerances, surface roughness, surface treatment, quantity and any special inspection requirements.

For complex components, a 3D model together with a 2D drawing is preferred because the 3D model defines the geometry while the 2D drawing communicates critical dimensions, tolerances and technical requirements.

Before production, our engineers review the design for manufacturability and identify potential issues such as deep cavities, thin walls, difficult-to-machine features, tight tolerances, tool access and surface finishing requirements.

RuiXing MFG provides custom CNC machining services for precision components manufactured according to customer drawings and technical specifications. Our capabilities include CNC milling, CNC turning, 5-axis machining, Swiss-type turning and turn-mill machining for complex and precision components.

We manufacture both prototypes and production parts, with quantities ranging from single samples to larger batch production depending on part size, geometry, material and production requirements.

Our machining capabilities cover metals and engineering plastics, including aluminum, stainless steel, brass, titanium alloys, PEEK, PEEK GF30, POM, PTFE, nylon, PEI and other engineering materials.

For each RFQ, our engineering team reviews the drawing, material, tolerances, geometry, quantity and finishing requirements before recommending an appropriate manufacturing process.
