CNC milling can achieve extremely high machining precision, usually reaching the micron level. This is due to our team’s precise control of the CNC system and the high rigidity of the machine tool structure.
For single products, the delivery time is usually 3 to 7 days; for batch products, it can be 10 to 30 days depending on the quantity. CNC milling machines can quickly complete the processing of complex parts, significantly shortening the production cycle. Multi-axis linkage and automatic tool change functions make the machining process more efficient. Automatic CNC programming also helps improve production efficiency.
CNC milling machines can process various complex-shaped parts, including curved surfaces, spiral surfaces, and irregular surfaces. Multi-axis CNC milling machines are especially good at processing complex three-dimensional structures. For example, complex-shaped products in aerospace, fluid industries, and transportation industries, such as impellers, blades, disks, and nozzle rings.
Due to the precise control of the CNC system over the machining process, CNC milling has very high repeatability. The size and shape of the parts processed each time can remain consistent.
CNC milling machines can quickly adapt to different part processing requirements by changing programs, offering high flexible manufacturing capabilities. This makes it possible to produce single pieces with multiple specifications and small batches with a variety of products.
