CNC milling machine compared with ordinary milling machine, with high processing accuracy, complex shape of machined parts, machining a wide range of characteristics. According to the characteristics of CNC milling machine, the contents suitable for CNC milling machine machining mainly have the following categories: Curve contour or surface and other complex structures: the plane curve contour of the workpiece, that is, the part has internal and external contours for the complex curve, the processing surface is parallel or perpendicular to the horizontal plane. In CNC Milling Machining, it is generally necessary to use only the two-coordinate linkage of the three-coordinate CNC milling machine to process.
The surface of the CNC Metal Milling parts is generally a surface where the points on the surface change in three-dimensional spatial coordinates. It is generally designed by a mathematical model. During the machining process, the milling tool and the machined surface always maintain point contact. Curved surface parts are generally processed using a three-coordinate CNC milling machine, which often requires the use of a computer for programming processing.
2.Ordinary milling machine is difficult to process the structure of the workpiece.
For the size, scribing, detection of a large number of parts, difficult to observe and control, ordinary milling machine suitable for CNC milling machine processing, should be selected to use CNC milling machine processing.
When processing on ordinary milling machine, it is difficult to ensure the dimensional accuracy, form accuracy and surface roughness of the workpiece, should be selected for processing with CNC milling machine.
In mass production, due to the high positioning accuracy and repeat positioning accuracy of the CNC milling machine itself, it can avoid various errors caused by human factors in ordinary milling machine processing, so the CNC milling machine is easy to ensure success. The consistency of the batch parts improves the machining accuracy and the quality is more stable.
