Our Advanced Machining Capabilities
We are not just a simple low-end parts supplier. Equipped with 3-axis, 4-axis, and 5-axis simultaneous CNC milling machines, we can handle both simple flat parts and highly complex precision components, to meet your most demanding requirements:
- Full Axis Support: 3-axis, 4-axis, 5-axis simultaneous machining for complex curved surfaces
- Workpiece Size: Up to 1200 x 800 x 600 mm, covering most industrial part sizes
- Thin Wall Machining: Minimum 0.5mm wall thickness for lightweight aluminum parts
- Deep Cavity Machining: Up to 10:1 depth-to-diameter ratio for internal cavity parts
- Micro Machining: From 0.1mm micro holes to large diameter boring, covering all precision needs
- One Setup Machining: Complete multi-face machining in one clamp, eliminating clamping error
Internal Test Data (For Reference Only): Our 5-axis milling achieves positioning accuracy of ±0.003mm within 1000mm travel, with surface roughness as low as Ra 0.4μm. Compared with traditional 3-axis machining, our 5-axis process improves production efficiency by over 60% for complex parts.
Precision Tolerance & Batch Consistency
We understand that your parts need to fit perfectly, no matter it is a prototype or 10000 pcs mass production. Our precision control ensures that every part meets your tolerance requirements, with consistent quality for batch production, so you don’t need to worry about rework or assembly issues.
- Standard Precision: Comply with ISO 2768 fine precision standard for general parts
- Critical Tolerance: Up to ±0.005mm for key dimensions, meeting aerospace and medical requirements
- Full Inspection: Use CMM (Coordinate Measuring Machine) to inspect all critical dimensions
- Batch Consistency: Stable process control to ensure consistent quality for large volume orders
Batch Production Test Data (For Reference Only): In our mass production test for 1000 pieces of 5052 aluminum parts, the CPK value of hole position tolerance reached 1.72, which is far higher than the industry standard of 1.33, ensuring that every part can fit perfectly in assembly.
Learn more about our tolerance standards in our Aluminum CNC Machining Tolerance Guide.

Anodizing
Comply with MIL-A-8625 Type II / Type III hard coat standard. Improves corrosion and wear resistance, available in multiple colors.
Bead Blasting
Creates a uniform matte surface, removes machining marks, improves surface appearance and coating adhesion.
Polishing
Creates a smooth, reflective surface, ideal for decorative parts, medical components, and high-end consumer products.
Powder Coating
Provides a durable, protective coating with a wide range of color options, excellent corrosion resistance for outdoor use.
Chem Film
Also known as alodine coating, provides corrosion resistance and good electrical conductivity for electronic components.
Electroplating
Nickel, chrome, or zinc plating, improves wear resistance, corrosion resistance, and electrical conductivity.
