Why aluminum-only expertise matters
Faster cutting, controlled results
General machine shops must constantly balance the needs of steel, titanium, plastics, and other materials. Our dedicated aluminum focus means every setup, cutter, and toolpath is selected around the behavior of aluminum alloys.
The result is efficient material removal for complex parts, including thin-wall enclosures, large pockets, and structural robotics components, without treating speed and quality as competing goals.
Deformation control
Manage thermal expansion and internal stress release during large pocketing operations.
Surface integrity
Optimized cutting parameters support superior surface finishes from Ra 0.8–3.2 μm.
Tooling optimization
Specialized tool geometry helps prevent built-up edge and maintain consistent high-speed passes.
Anodizing preparation
Strict dimensional control accounts for anodized layer thickness and downstream finishing requirements.
Technical capabilities
Built for complex aluminum components
Our Shenzhen facility supports demanding geometries and production requirements, from thin-wall enclosures to structural robotics components.

Common project questions
A focused approach to aluminum machining
How does high-speed machining help shorten lead times? +
High-RPM spindles, large feed rates, and efficient chip evacuation remove material faster, particularly in aluminum pocketing and contouring operations. Optimized toolpaths help reduce cycle time while maintaining dimensional control.
Which aluminum grades can you machine? +
Common grades include 6061, 6063, 6082, 7075, 2024, 5052, and 5083. Share your material specification with your drawings so the process can be planned around the alloy’s properties.
Can you support anodized aluminum parts? +
Yes. Dimensional tolerances are managed with the thickness of the anodized layer in mind. Available finishing options include clear, black, and hard anodizing, along with bead blasting and powder coating.
