3+2-axis CNC machining, also known as positioning five-axis machining, is a manufacturing process that utilizes three linear axes (X, Y, Z) and two rotational axes (A, B) to position the workpiece at fixed angles. This setup allows for the machining of complex geometries without the need for continuous five-axis linkage. The primary advantages of 3+2-axis CNC machining include:
- Single Clamping: By reducing the number of clamping operations, this method enhances accuracy (tolerance ±0.02 mm) and efficiency.
- Cost-Effectiveness: It offers a 30% cost reduction compared to full five-axis equipment, making it suitable for complex parts that do not require dynamic linkage, such as aerospace brackets and medical implant bases.
- Design Flexibility: Supports the creation of intricate geometric features, including bevels, deep cavities, and special-shaped holes.

How to Choose a Reliable 3+2-Axis CNC Provider
When selecting a 3+2-axis CNC machining provider, consider the following factors:
- Technical Capability Assessment
- Equipment List: Ensure the supplier is equipped with high-precision five-axis positioning machines, such as Haas UMC-750 or Mazak VTC series.
- Process Experience: Verify if the provider holds industry certifications relevant to your sector, such as AS9100 for aerospace or ISO 13485 for medical devices.
- Post-Processing Support: Check for additional services like surface treatment (anodizing, sandblasting), heat treatment (quenching, annealing), and non-destructive testing (X-ray flaw detection).
- Service Model Comparison
- Local Suppliers: Suitable for rapid prototype verification with quick turnaround times (1-3 days) but may come at a higher cost (e.g., single order $500+).
- Online Suppliers (e.g., Great Light):
- Price Advantage: Bulk order unit prices as low as $50 per piece (aluminum alloy), 40-60% lower than local suppliers.
- Global Supply Chain: Ability to source special materials like titanium alloy and high-temperature alloys.
- Digital Services: Offer online real-time quotations, production progress tracking, and 3D model Design for Manufacturability (DFM) analysis.
Case Study: Aerospace Bracket Manufacturing
- Requirement: Manufacture 100 titanium alloy brackets with multi-angle mounting holes and curved surface contours, tolerance ±0.015 mm.
- Challenge: Local supplier’s delivery time was 8 weeks, and the price was $800 per unit.
- Solution: Opted for Great Light’s 3+2-axis service, optimizing tool paths and cooling parameters.
- Result: Cost reduced to $320 per unit, delivery time shortened to 4 weeks, with a defect rate of less than 0.2%.
