CNC milling characteristics and processing content suitable for CNC milling

1. Features of CNC milling

1.Flexible and versatile: CNC milling machines and machining centers are suitable for the processing of various types of workpieces with different structures and shapes, and can complete drilling, boring, reaming, milling planes, milling bevels, milling grooves, milling surfaces (cams), tapping threads, etc machining.

2. High machining accuracy: CNC milling machines and machining centers have high machining accuracy, and generally can guarantee the accuracy of the workpiece. In addition, CNC machining also avoids the operator's operation errors, the same batch of processed parts has good size identity, and greatly improves product quality.

3. High production efficiency: CNC milling machine and machining center have the functions of milling machine, boring machine and drilling machine, which make the process highly concentrated, greatly improving the production efficiency and reducing the workpiece clamping error. The spindle speed of CNC milling machine realizes stepless speed change, which is conducive to selecting the best cutting amount. The CNC milling machine has the functions of fast forward, fast reverse and fast positioning, which can greatly reduce the maneuvering time.

4. It can process complex shapes: in addition to milling the surface of various parts that can be milled by ordinary milling machines, it can also mill plane curve contours and space curved contours that ordinary milling machines cannot mill. This is because CNC machine tools have multiple feed coordinates Features of shaft linkage.

5. Reducing the labor intensity of the operator: CNC milling machine automatically completes the parts processing according to the pre-programmed machining program. Apart from operating the keyboard, loading and unloading tools, workpieces and intermediate measurement and observing the operation of the machine tool, the operator does not need to repeat heavy burden Sexual manual operation greatly reduces labor intensity.

Second, the processing content suitable for CNC milling

1. Compared with ordinary milling machine, CNC milling machine has the characteristics of high processing accuracy, complex shape of processing parts, and wide processing range. According to the characteristics of CNC milling machines, the content suitable for CNC milling machines mainly includes the following categories: Curved contours or curved surfaces and other complex structures: the plane curve contour of the workpiece, which means that the parts have inner and outer contours of complex curves, and the processed surface is parallel or perpendicular level. In CNC milling, they are usually processed by two coordinate linkages of three-coordinate CNC milling machines.

The curved surface of the workpiece generally refers to the surface where the points on the surface change in three-dimensional space coordinates. It is generally designed by a mathematical model. During processing, the milling cutter and the processing surface are always in point contact. The machining of curved surface parts generally adopts a three-axis coordinated CNC milling machine, which often needs to be programmed and processed by means of a computer.

2. Workpiece structure that is difficult to process on ordinary milling machines: For many sizes, difficult to mark and detect, parts that are difficult to observe and control on ordinary milling machines are suitable for CNC milling machines, and CNC milling machines should be selected.
