The CNC milling machine can perform milling processing of complex-shaped hardware parts. Milling is to fix the blank, and use a high-speed rotating milling cutter to move on the blank to cut out the required shapes and features. Traditional milling is mostly used to mill simple shape features such as contours and grooves. CNC milling machines can process complex shapes and features. The milling and boring machining center can perform three-axis or multi-axis finishing. Used for processing, molds, inspection tools, aluminum cavity prototypes, thin-walled complex curved surfaces, artificial prostheses, impeller blades, etc. When choosing CNC milling processing, we should give full play to the advantages of CNC milling machine.
Milling is a common metal cold processing method. The difference from turning is that in milling, the tool is driven by the spindle to rotate at a high speed, while the workpiece is relatively stationary.
The difference between turning and milling: Turning is used to process revolving parts. The parts are clamped on the main shaft of the machine tool through three gripping chucks and rotated at high speed. Then use a turning tool to move the tool according to the generatrix of the revolving body, turning out the appearance of the product. The lathe can also process inner holes, threads, knurling, etc.
Milling process
(1) Curve contours on milling hardware workpieces, straight lines, arcs, threads or spiral curves, especially non-circular curves and list curve contours given by mathematical expressions.
(2) It is possible to mill the spatial curve or surface of the given mathematical model.
(3) Although the shape of the milling pin is simple, the parts are of various sizes and difficult to detect.
(4) CNC milling can be selected for the inner cavity of the product and the inside of the box that are difficult to observe, control and detect during the processing of ordinary machine tools.
(5) Holes or flat parts with strict size requirements can be milled.
(6) A simple surface or shape that can be milled in one clamping.
(7) The use of CNC milling processing can effectively increase productivity and reduce labor intensity.
The main processing products suitable for CNC milling include the following categories: flat contour parts, variable bevel parts, spatial curved contour parts, holes and threads, etc.
