The future development of CNC turning and milling processing is mainly reflected in three aspects

In CNC turning-milling compound processing, in order to improve the utilization rate of machine tools and reduce labor costs, automation has been paid more and more attention. At the same time, through the development of software, the machine tool can broaden the functions of operation, and can economically arrange the production schedule in the case of small production batches and short delivery cycles. In addition, increase the power of the machine tool so that it can adapt to diversified needs and broaden the range of specifications for grinding tools. Positioning and clamping of parts when finishing the cavity is to enable the workpiece to be quickly and correctly clamped on the machine tool, and it is not necessary to align one by one when processing a batch of workpieces, so this processing adopts the positioning method of two pins on one side. . This clamping method is fully in line with the characteristics of the machining center, and the cavity and all holes can be processed in one clamping.
In the future, the development of CNC turning-milling compound machining is mainly reflected in three aspects:
1. Application software development: Now the factory hopes that the higher the degree of automation in grinding, the better, regardless of the production batch size, the key to the problem is to achieve flexibility. Luo Baihui, secretary general of the International Moulding Association, said that the work of the Association’s Tool Committee in recent years includes the establishment of an automatic loading and unloading system for tools and grinding wheels to realize the grinding process without supervision or minimize supervision. He emphasized that the reason for the increasing importance of software is that the number of high-level workers who are able to manually grind complex tools is decreasing. In addition, hand-made tools are also difficult to meet the requirements of modern machine tools for cutting speed and accuracy. Compared with CNC grinding, manual grinding will reduce the quality and consistency of the cutting edge. Because during manual grinding, the tool must lean on the supporting piece, and the grinding direction of the grinding wheel points to the cutting edge, which will produce edge burrs. The opposite is true for CNC grinding. There is no need for a support plate during work, and the grinding direction deviates from the cutting edge, so there will be no edge burrs.
2. Automation: When the tool manufacturer produces new tools, the efficiency is high due to the large batches. But the tool grinding plant does not have this condition, and only solves the efficiency problem through automation. The tool dresser does not require unmanned operation of the machine tool, but hopes that one operator can take care of multiple machine tools to control costs.
3. High precision: Many manufacturers regard reducing operation time as their primary goal, but other manufacturers put the quality of parts in the most important position (such as high-precision tool and medical parts manufacturers). With the improvement of grinding machine production technology, newly developed machine tools can guarantee very strict tolerances and exceptional finishes.
