In the precision stage of modern manufacturing industry, CNC metal milling machine has become an indispensable protagonist with its great processing ability and flexibility. The deep application of this technology not only promotes the efficiency and accuracy of mechanical processing, but also promotes the intelligent transformation of industrial production. This paper will discuss the machining process characteristics of CNC metal milling machine.

The refinement of processing technology

The core of CNC metal milling machine lies in its ability to perform complex program control and achieve accurate machining from flat to three-dimensional surface. The processing technology is roughly divided into three categories: surface milling, contour milling and surface machining. Planar parts are completed by simple and efficient surface milling, while curved and variable bevel parts require more complex tool paths and multi-axis linkage technology to ensure smooth and accurate machining surfaces. The application of ball tool in surface machining, because it can reduce overcutting, has become the choice for dealing with complex geometric shapes.

Fixture and process optimization

Selecting the appropriate fixture is the key to ensure the machining accuracy of CNC metal milling machine. The machine vise is suitable for the quick clamping of small parts, while the chuck is suitable for the fixing of round workpieces. When dealing with special shapes or large workpieces, the use of clamping plates and custom fixtures is particularly important, they ensure stability during processing and reduce deformation through reasonable clamping layout.
