Our CNC Milling Capabilities
From rapid prototyping to end-use production, we transform your concepts into high-precision components. Our comprehensive CNC milling solutions deliver complex geometries with exceptional accuracy with our cutting-edge 3 and 5-axis milling centers. Supported by both vertical and horizontal milling setups, we optimize the manufacturing process for varied part sizes and complexities, ensuring rigorous quality standards and reliable, fast turnaround.

3-Axis CNC Milling
3-axis CNC milling provides a highly cost-effective solution for parts with simpler geometries. With a lower entry cost compared to multi-axis processes, it remains the ideal choice for projects in simplicity and affordability.

3+2-Axis CNC Milling
3+2-axis CNC milling is a powerful technique for manufacturing intricate parts via intelligently locking a part in the perfect position for a 3-axis cut. It allows for intricate features to be machined in a single setup, while without the full cost and complexity of continuous 5-axis programming.

5-Axis CNC Milling
5-axis CNC milling delivers unmatched precision and efficiency for the most complex part geometries. By moving all five axes simultaneously, it produces superior surface finishes and intricate contours in a single setup, dramatically reducing lead times and eliminating cumulative fixture errors.
CNC Milling Service Tolerances
Our standard CNC machining tolerances adhere to ISO 2768 (medium) for machined plastics and ISO 2768 (fine) for machined metals. If your design has critical dimensions or requires higher precision than these standards, please clearly indicate them on your drawings or reach out to our sales.

Advantages of CNC Milling
Unmatched Precision & Consistency
Achieves tight tolerances and identical results for every part, from prototypes to production runs, eliminating human error.
Versatility in Complex Geometry
Excels at machining intricate shapes that are difficult or impossible to produce manually, enabling high customization.
High Efficiency & Rapid Turnaround
Advanced equipment and optimized workflows enable faster setup and processing, significantly shortening lead times for prototypes and small batches.
Broad Material Compatibility
Capable of machining a wide range of industrial materials, including various metals, plastics, composites, wood and glass.
Excellent Repeatability
Once a program is verified, it can be reused to produce identical parts with zero deviation, ideal for scalable small-batch production.
Superior Surface Finish
Delivers high-quality surface finishes directly from the machine (Ra customizable), often minimizing or eliminating the need for additional post-processing.
Integrated Quality Control
Combines machining with multi-stage inspection (in-process, CMM, vision measurement) to ensure every part meets strict specifications and standards.

Feature |
Core Requirements |
Common Reference Values |
|
Internal fillet |
Avoid sharp corners; fillet radius matches tool diameter |
Fillet radius ≥ tool radius, recommended ≥ 0.8mm |
|
Cavity/groove |
Control width-depth ratio to prevent vibration and tool breakage |
Depth ≤ 4× width; ≤ 5× tool diameter for steel, ≤ 10× tool diameter for aluminum |
|
Wall thickness |
Ensure rigidity to avoid deformation/chatter |
≥ 0.8mm for metals (minimum 0.5mm), ≥ 1.5mm for plastics |
|
Deep hole |
Through-holes are preferred over blind holes; strictly control depth for blind holes |
Depth ≤ 3× hole diameter; chip removal and tool rigidity to be considered for deep holes |
|
Undercut |
Eliminate or adjust position as much as possible |
Multi-axis machine tools or split assembly adopted if necessary |
|
Thin-walled/slender structure |
Increase thickness or add reinforcing ribs |
Length of slender structure ≤ 10× thickness to avoid vibration fracture |
