CNC machining general processing range

Since the emergence of numerical control, it has been widely used in the field of machining. Today we will share with you the processing characteristics and application scope of CNC milling.

CNC milling processing features

1. Flexible and diverse: CNC milling machines and processing plants are suitable for processing workpieces of various structures and shapes, and can complete drilling, boring, reaming, plane milling, groove milling, groove milling, face milling (CAM), tapping and other processing.

two,. High machining accuracy: CNC milling machines and processing plants have high machining accuracy, which can ensure the workpiece accuracy under normal conditions. In addition, CNC milling also avoids operator error. Therefore, the dimensional consistency of the same batch of machined parts will be high, which will greatly improve the product quality.

3. High production efficiency: CNC milling machines and processing plants have the functions of milling, boring and drilling machines, which make the process highly concentrated, greatly improve production efficiency and reduce workpiece clamping errors. The spindle speed of CNC milling machines can be infinitely variable, which helps with the selected cutting parameters. The CNC milling machine has the functions of fast forward, fast reverse and fast positioning, which can greatly reduce the operation time.

4. Complex machining shapes: Because the CNC machine tool has the characteristics of multi-feed coordinate axis linkage, the CNC milling machine can not only mill the surfaces of various parts that ordinary milling machines can mill, but also mill the plane curve contours and space surfaces that ordinary milling machines cannot mill. contour.

5. Reduce the labor intensity of the operator: CNC milling machine automatically completes the processing of parts according to the pre-programmed processing program. In addition to operating the keyboard, loading and unloading tools and workpieces, intermediate measurements and observing machine operations, the operator does not need to carry out heavy and repetitive manual operations, which greatly reduces labor intensity.

Scope of application of CNC milling

1. CNC milling machine is suitable for processing complex structures, such as curved contours or curved surfaces: the plane curve contour of the workpiece means that the inner and outer contours of the workpiece are complex curves, and the machining surface is parallel or perpendicular to the horizontal plane. CNC milling can only be processed by the linkage of two coordinates of the three-coordinate CNC milling machine.

two,. Workpiece structures that are difficult to process on ordinary milling machines: For parts of various sizes, difficult to mark and detect, and difficult to observe and control, CNC milling machines should be selected for processing.

3. When processing on an ordinary milling machine, it is difficult to ensure the dimensional accuracy, shape and position accuracy and surface roughness of the workpiece. CNC milling should be used.
