Love better to launch machine tools with high precision measurement

Nc machine tool as a kind of precision processing equipment, has been more and more widely applied in the field of precision machining.In order to ensure that the numerical control machine tool has the very high machining accuracy, on the machine is equipped with appropriate displacement measuring device is necessary.As & other;Gusu talents & throughout;, graduate school of Chinese academy of sciences, associate professor of electrical engineering, southeast university post-doctoral, lead ChuJianHua entrepreneurial team, through five years of technology, and developed the & other;Active ball grating displacement sensor measurement & throughout;.Reporter in love good company met this kind of measuring instrument, the equipment is mainly composed of a metal ball from the land scale measurement and a signal equipment, ChuJianHua introduction, this & otherThe ball grid scale & throughout;Whole sealing structure is adopted to IP67 protection grade standard, its measurement precision is not affected by oil, water, iron and other common pollutants affect workshop, ruler of the warranty period can be up to 10 years.& other;General measurement sensor is not hard to do, I study hard, difficult in big mechanical implementation of advanced measurement.Throughout the &;ChuJianHua explanation: & other;An open large nc machine tools, electromagnetic interference is very big, and there are oil, in such bad environment, still can ensure the measuring accuracy of 1 micron, this is very not easy.Throughout the &;

for a long time, on the precision machine tool configuration is a set of three coordinate displacement measuring device, mainly imported from abroad.According to introducing, the measuring instrument accuracy of similar foreign is 5 microns, a group of more than ten meters long three coordinates measuring instrument for about 7 to 80000 yuan, and love not only higher precision of products, the price is only half of the same products abroad.ChuJianHua revealed that China’s existing stock of 8 million sets of machine tools need to be modified, in addition, an annual increase of precision cutting machine more than 70 sets.He chuckles & other;Each machine needs to be equipped with precision measuring instruments, this is a & lsquo;Blue ocean market & rsquo;Every year, there will be billions of market demand.Throughout the &;
& have spentBecause see the demand in the industry, ChuJianHua lead the team to focus on automation measurement field, during the period of product performance testing, he often spends one night, in the machine tool workshop a continuous test.& other;The traditional grating measurement with the defect of instability, mainly by the environment, such as dust pollution, we solved this problem by electromagnetic principle, guarantee under the condition of the processing environment is very bad, the instrument can work normally.Throughout the &;
& have spentIn 2017, love good company won the jiangsu province private scientific and technological enterprise qualification.Product original ball grid structure, the active methods, key technology such as segmentation processing, weak signal processing is applied for two PCT patent, products comprehensive performance reached the international first-class level.It is understood that in addition to & other;The ball grid scale & throughout;, ChuJianHua r&d team to develop the space level precision Angle measuring equipment, has been successfully used in aeronautics and astronautics.The angular resolution can reach 0.1 & Prime;(seconds), measurement accuracy can reach & plusmn;0.2 & Prime;, the environment temperature range in – 40 ℃ to + 85 ℃, also can work normally under the strong shock.At present, the project has been successfully used in small satellite engineering center in Shanghai, and signed a contract in China academy of space technology.
