Type of CNC milling machine services
This machining service uses milling tools to cut rough workpieces to produce finished parts and products.CNC milling systems typically have three linear degrees of freedom: X/Y/Z axes, which allow for precise cutting in the horizontal as well as the vertical plane, making them ideal for machining parts with complex geometries, such as curves, surfaces, and concave/convex machining planes. At Yonglihao Machinery, we offer 3-axis/4-axis/5-axis machining options for parts of varying complexity. It is a CNC machining service that is suitable for both high volume production and small volume customised machining. It is currently used as the primary means of machining in the manufacturing industry.
