Key processing methods of turning milling compound machine
Although CNC machine tools have been widely accepted and applied, the development trend of metal material drilling machine tools is still too traditional, and special machine tools are developing in accordance with the role of milling, cutting and milling respectively.
Reduce the clamping frequency of workpieces and the frequency of moving from this machine tool to another machine tool to reduce the shutdown time and improve the processing efficiency; This kind of demand for improving quality and efficiency has led to the transformation of refitting the rotary table on the traditional machining center, thus completing the turning milling composite machining. Today's intelligent multi task machine tools contain the B axis which can make the CNC blade rotate and move, excellent automatic control system and front-end CAM software, so that the workpiece can be processed according to a specific daily task according to a clamping.
Key processing methods of turning milling compound machine:
Machining non continuous surface layer can cause intermittent drilling, such as machining various grooves and back gouging. In classical milling, this actual operation can cause impact load of unfavorable machining, resulting in poor quality of machined surface and early damage of milling cutter. In turning milling compound machining, the milling cutter used is the turning cutter, and the cutting itself also carries out intermittent drilling in the periodic change of load.
When the raw material to be processed is long chip material. In milling, chip forming is an unsolvable problem; Finding the most suitable chip breaking groove for lathe tools is not such an easy daily task. The turning tool used for turning milling compound processing causes short chips, which obviously enhances the control of chips.
Taking the machining of engine crankshaft with camshaft journal and machine tool spindle as an example, in the milling process, for example, the axial force quality of engine crankshaft journal, axial force camshaft and other workpieces can cause a sense of imbalance, which will cause bad harm to the processing, while the turning milling composite processing can prevent such adverse effects due to the low speed ratio of the workpieces.
In production, the introduction of turning milling compound processing not only deals with processing difficulties but also greatly improves the efficiency. Using relatively new processing methods may greatly increase production efficiency when there are appropriate intelligent machine tools and cutting tools.
Turning milling compound machining shows its own advantages. Turning milling composite processing is the whole process of processing rotating workpieces according to turning tools. This kind of processing technology integrates many advantages of cutting and milling technology, and improves productivity in work.
