5-axis CNC Machining Technical Analysis

5-axis CNC machining processes

complex parts through the linear motion of the X, Y, and Z axes and the rotational linkage of the A/B axes, breaking through the geometric limitations of traditional manufacturing and achieving high-precision processing of complex curved surfaces. The advantage of five-axis CNC machining lies in reducing the number of clamping operations and enhancing the forming ability of complex geomeuses. It is particularly suitable for the manufacturing of high-value-added parts in fields such as aerospace and high-end medical care.

Shengyi Intelligent Technology, adhering to aerospace-grade precision standards (AS9100D) and the concept of green manufacturing, provides customers with a full-chain solution from design simulation to post-processing.

ISO 14001:2015ISO 14001 certification drives us to practice sustainable manufacturing, with green production as the core goal. We optimize cutting parameters to reduce the waste rate. The recovery rate of aluminum chips reaches 95%, and the coolant circulation system reduces hazardous waste emissions by 30%.
The upgrade of high-efficiency equipment has reduced energy consumption (case: annual electricity bill savings of 80,000 yuan), meeting the ESG audit standards of European and American customers.

ISO 9001:2015Through ISO 9001 certification, we have established a closed-loop of full-process quality management: from drawing review to finished product inspection, precise control is achieved. The standardized process ensures that the dimensional tolerance of parts is stable (±0.02mm), and the surface finish reaches Ra1.6μm. First Piece Inspection (FAI) and Process Monitoring (SPC) intercept batch defects. For example, in the processing of a certain medical part, the defect rate was reduced to 0.15%.

5-axis CNC Machining Frequently Asked Questions:

Does five-axis machining support super-large parts?

The stroke of Shengyi Intelligent Technology's five-axis machine tool is 300×300×300mm (X×Y×Z). If the part exceeds this range, we can provide a segmented processing + precision welding solution.
Why is the cost of five-axis machining relatively high?

Investment in five-axis cnc machining equipment (about 3 to 8 times that of three-axis), high programming complexity (CAM software requires a five-axis module), and rapid tool wear (tool life for titanium alloy processing is reduced by 40%).
What is the minimum Order quantity (MOQ)?

Support minimum order quantity. It is recommended that the order quantity be no more than 50 pieces to balance cost-effectiveness.
