- good surface finish potential
For parts with more complex geometry, milling can also be combined with multi-axis machining to reduce setups and improve consistency.
2. CNC Turning Services
CNC turning services are primarily used for round or cylindrical parts. In this process, the workpiece rotates while cutting tools remove material to create diameters, grooves, faces, tapers, bores, and threads.
CNC turning is commonly used for:
- shafts
- bushings
- sleeves
- connectors
- threaded components
- valve parts
- precision pins
Turning is efficient for rotationally symmetric parts and is often used in both simple and high-precision applications.
Benefits of CNC turning
- efficient production of round parts
- excellent concentricity control
- strong repeatability
- suitable for internal and external threads
- good productivity for batch production
In many projects, turning is followed by milling, drilling, or surface treatment to complete the part.
3. 5 Axis CNC Machining Services
5 Axis CNC Machining Services are used for parts with complex geometry, multiple machining angles, curved surfaces, and tight tolerance relationships across several faces.
Unlike standard 3-axis machining, 5-axis machining allows the tool and/or part to move across more directions during the cutting process. This reduces the number of setups and improves accuracy for complex components.
Typical applications include:
- impellers
- aerospace components
- complex housings
- medical parts
- precision tooling
- parts with compound angles
Benefits of 5-axis machining
- fewer setups
- higher geometric accuracy
- shorter production time for complex parts
- better access to difficult features
- improved surface consistency
For customers developing advanced mechanical components, 5-axis machining is often the best option when standard milling cannot efficiently achieve the required shape.
4. Swiss Machining Services
Swiss Machining Services are ideal for small, long, and high-precision turned parts. Swiss-type machines are designed to provide excellent support close to the cutting zone, which makes them particularly effective for slender parts with strict tolerance requirements.
Swiss machining is commonly used for:
- medical pins
- miniature shafts
- precision fasteners
- connectors
- electronic components
- small threaded parts
Benefits of Swiss machining

Precision CNC Machining Services refer to machining solutions focused on tighter tolerances, more demanding dimensional control, and higher quality standards than general machining work.
At Daxin Century, precision machining is not a separate machine type—it is a manufacturing standard that guides how we approach programming, setup, tooling, measurement, and process control.
Precision CNC machining is especially important for:
- mating parts
- sealing surfaces
- alignment features
- press-fit areas
- precision assemblies
- custom industrial components
What precision machining requires
- stable programming and tooling strategy

For many custom parts, working with one supplier that can handle both machining and finishing helps simplify communication and reduce lead time.
V. Materials, Tolerances, and Surface Finish Capabilities
A strong CNC machining supplier must be able to match the manufacturing process to the material and functional needs of the part.
At Daxin Century, we work with a variety of materials commonly used in precision machining projects, including:
Common metal materials
- aluminum alloys
- stainless steel
- carbon steel
- alloy steel
- brass
- copper
Common plastic materials
- POM
- PTFE
- nylon
- acrylic
- ABS
- PEEK
- other engineering plastics
Different materials require different tooling strategies, cutting conditions, and finishing processes. For example:
- aluminum is efficient to machine and suitable for lightweight components
- stainless steel offers corrosion resistance but requires more careful heat control
- brass machines well and is commonly used for fittings and electrical parts
- engineering plastics may need special attention to deformation and burr control
In terms of part quality, tolerance capability depends on material, geometry, feature size, and process route. For precision projects, machining must also consider:
- heat treatment allowance
- surface finish requirements
- assembly fit
- inspection method
- downstream processing
This is why quoting a CNC machined part should never be based on geometry alone. Material condition and finish requirements matter just as much.
