Service Overview
Four-axis CNC machining centers, building upon the three-axis (X, Y, Z) linkage, add a rotary axis (usually the A or B axis), enabling the machining of multiple faces of a part in a single setup, greatly expanding the machining range and flexibility. This machining method effectively reduces the number of setups, avoids positioning errors caused by multiple setups, and improves the machining accuracy and surface quality of the parts.
We are equipped with high-precision four-axis linkage centers, featuring advanced control systems and high-precision transmission components, which can precisely control the tool’s movement trajectory in space, focusing on providing complex five-sided surface machining solutions. Our professional programmers use advanced programming software based on the part’s 3D model to generate complex and precise machining programs, ensuring that every machining detail is perfectly presented. Whether it’s four-axis milling of aerospace impellers with complex curved surfaces or multi-faceted machining of intricate medical joint prostheses, we can meet our customers’ high-precision machining needs with our four-axis machining technology.

Frequently Asked Questions
What are the advantages of four-axis CNC machining compared to three-axis machining?
Four-axis machining adds a rotary axis to the three-axis machining process, allowing more surfaces to be machined in a single setup, reducing clamping errors and improving machining accuracy; it can machine more complex spatial curved surface parts; and it has higher machining efficiency, which can shorten machining time and reduce costs.
What special shapes of parts can be machined by four-axis CNC machining?
It can process complex pentahedral parts such as impellers, propellers, twisted curved surface structures, and multiple planes with different angles, and is widely used in the processing of complex parts in industries such as aerospace, automobiles, and molds.
Are there any special material requirements for four-axis CNC machining?
Four-axis machining has no special requirements for the materials themselves; common metallic and non-metallic materials such as aluminum, steel, copper, titanium alloys, plastics, and ceramics can all be machined. However, different materials require different machining process parameters, such as cutting speed and feed rate, to be adjusted according to their characteristics to ensure machining quality and efficiency.
If a part requires surface treatment, will surface treatment after four-axis CNC machining affect its accuracy?
We will allow appropriate machining allowances during the processing to accommodate surface treatment steps. Simultaneously, advanced processes and equipment will be employed during surface treatment, and factors such as deformation during the process will be strictly controlled to minimize the impact on precision and ensure that the final product meets precision requirements.
How is the price of four-axis CNC machining determined?
The quote is determined based on a comprehensive consideration of factors such as the complexity of the part (shape, size, precision requirements, etc.), the difficulty of the machining process, material costs, machining time, equipment wear and tear, and whether special tooling or fixtures are required. We will conduct an accurate calculation and provide a reasonable quote based on the detailed drawings and specific requirements you provide.
