Shanghe recycling single point scrap machine tool if the spindle speed is abnormal, that is, after the spindle is given the command speed, The reaction speed on is inconsistent with the command speed (generally less than the command speed). It may be that the spindle of CNC machining center is not smooth and abnormal. The sound is loud and slow. In some cases, the motor may even have overcurrent

high-end equipment of CNC machine tools; Numerical control machining center numerical control turret punch numerical control cutting board she particularly likes playing mahjong machine bending machine numerical control laser cutting machine numerical control drilling machine numerical control milling machine numerical control lathe numerical control grinding machine numerical control planing machine numerical control boring machine numerical control hobbing machine grinding machine and other new year imagination gear equipment for new material industry, slow wire cutting EDM and other domestic and imported second-hand numerical control machine tool high-end equipment. CNC machine tool industry is a technology intensive, capital intensive and talent intensive industry, with industrial characteristics of multiple categories, varieties, small batches and high social benefits. At present, the medium and high-end CNC systems and key functional components supporting the industry mainly rely on imports. In 2016, the total import volume of China's machine tools was about 7.5 billion US dollars, and there is huge room for import substitution. At the same time, compared with the NC rate of 60% - 70% of manufacturing equipment in Japan, Germany and the developed countries of the United States, the NC rate of machine tools that can alarm in time when they do not meet the following table is still low. With the upgrading of downstream industries in the future, China's machine tool industry will undergo structural adjustment, and CNC machine tools will gradually replace ordinary machine tools

for the spindle of the NC machining center, when the encoder responds, the speed command "s" given by the NC machining center machine is followed by a number, which will reflect the same value on the system flash. The main driver of the spindle of CNC machining center can be used with belt transmission device or gear transmission device. Most of them are now driven by synchronous belts in belt drives. The speed is abnormal. It may be that the synchronization device is too long, so it has a sliding missing step

however, there is still a certain gap between its products and foreign products in terms of function and performance reliability. In recent years, domestic CNC machine tool manufacturers have obtained some advanced CNC technologies through technology introduction, mergers and acquisitions at home and abroad, as well as foreign procurement. However, they lack research on basic technologies such as machine tool structure and accuracy, reliability and humanized design, and ignore the cultivation of independent development ability. There is still a large gap between domestic CNC machine tools and foreign countries in terms of technical level, performance and quality, which is also difficult to be recognized by most users. Recycling of second-hand sheet metal equipment: recycling of old plate shears and old bending machines. Some domestic CNC machine tool manufacturers do not pay enough attention to the improvement of the overall process and manufacturing level. The processing means are basically ordinary machine tools and inefficient cutting tools. Assembly and debugging are completely manual, and the processing quality cannot be stabilized and improved under the pressure of production progress. In addition, many domestic CNC machine tool manufacturers still use the original manual account management method for production management, and the low process level and management efficiency make enterprises unable to form a sufficient production scale

the coupling between the spindle of the NC machining center and the spindle encoder is also used with the synchronous belt, and the same situation may be lost in this step. However, the smoothness of the spindle of the CNC machining center is not good, or any bearing on the spindle may be burned out, resulting in excessive resistance of the CNC machining center and spindle rolling failure. External signal interference also constitutes this phenomenon

the first generation of multi wire cutting machine tools with independent intellectual property rights was born in China; On October 27th, 2007, China's second generation of multi wire cutting machine tools that passed the appraisal of scientific and technological achievements were born; Since 2008, it is the development stage of the third generation of high-precision, high-speed and special multi wire cutting machine; In 2010, the national major special project, the horizontal 300mm silicon wafer multi wire cutting machine, was successfully developed. From the comparison of the main technical indicators between domestic CNC multi wire cutting machine tools and foreign products, at present, domestic multi wire cutting machines mainly process small and medium-sized sizes, and the main indicators in this field have reached or exceeded the international advanced level. The scope of application has also been rapidly extended from the processing of simple semiconductor monocrystalline silicon to the processing industry of polycrystalline silicon, quartz crystal, gem, glass, piezoelectric ceramics and other materials. China began to independently develop and produce high-end precision processing equipment for hard and brittle materials such as grinding and polishing machines in the 1980s, and gradually realized the large-scale production of grinding and polishing machines in the 1990s
