Manufacturing Process Insight
1

5-Axis Simultaneous Milling

We utilize 5-axis machining centers to access the part from all angles. This allows us to machine complex undercuts and angled features in a single setup, reducing cumulative errors.

2

Lightweight Pocketing

Deep pockets are milled out of a solid block of Aluminum 6061-T6/7075, removing over 70% of the material weight while retaining the skeletal strength.

3

High-Speed Machining

We use specialized end mills and optimized tool paths to achieve a surface finish that often requires no manual polishing.

Key Features & Benefits
Extreme Precision

Extreme Precision

Tolerances are held to ±0.005mm on critical features.

Material Integrity

Material Integrity

Machining from a solid block ensures no internal voids or structural weaknesses compared to casting.

Complex Geometry

Complex Geometry

The 5-axis capability allows for organic shapes and non-standard angles that 3-axis machines cannot achieve.

Aesthetic Quality

Aesthetic Quality

The raw machined finish showcases the precision of modern manufacturing, often desired in high-tech industries.

FAQs
Q Q1: What file formats do you accept for quotation?
We prefer STEP (.stp) or IGS (.igs) files for 3D models, accompanied by PDF drawings for tolerance specifications.
Q Q2: How do you ensure the quality of complex parts?
We use CMM (Coordinate Measuring Machine) inspection to verify the geometry against the original 3D CAD model, ensuring every critical dimension meets the specified tolerances.
Q Q3: Can you do surface treatments after machining?
Yes, we offer Anodizing (Type II & III), Alodine, and Powder Coating tailored to aerospace or medical standards.
Q Q4: What is the typical lead time for a 5-axis CNC milled part?
Lead time depends on part complexity and quantity. For prototype orders, we typically deliver within 7–14 business days after design confirmation. Production runs are quoted on a case-by-case basis.
Q Q5: What is the minimum order quantity (MOQ) for CNC machined parts?
We support low-volume prototyping with an MOQ of 1 piece. Volume pricing is available for batch production orders, and we are happy to discuss your specific project requirements.
Q Q6: Can you machine materials other than aluminum?
Yes. In addition to Aluminum 6061-T6 and 7075, we regularly machine Titanium, Stainless Steel, Brass, Copper, and engineering plastics such as PEEK and Delrin, depending on your application requirements.
