Relevant statistics show that as the basis for CNC cutting technology , our tool manufacturing technology and performance in terms of quality measuring instruments , with foreign advanced level there is still a big gap . Measuring China's hardware industry after decades of construction and development, has formed a relatively complete product , with a certain scale of production and development capabilities of the industrial system , except for Japan to become the world's second largest producer of metal measuring tool . Precision machine manufacturing requires not only accuracy, stability and tools, fixtures to ensure accuracy , precision metal measuring meter also need to calibrate the measurement . Famous scientist Qian Xuesen has pointed out : "Information technology, including measurement technology, computer technology and communication technology and measuring technology is the key foundation ." Homemade metal measuring highlights continued , to precision measurement from the visual to the simple measurement, measurement technology advances protection of the manufacturing technology advances to a certain extent .    " Some in the process ( such as knife ) ; . Plenty of post- detection ( such as gear measuring instrument ) " precision machine manufacturing requires not only accuracy, stability and tools, fixtures to ensure accuracy , precision metal measuring tools also need to calibrate the meter to measure . Industry experts said the wind power industry, for example , to a certain extent represent and reflect the latest results of a national advanced technology and CNC cutting tools, technology and digital measurement and level measurement instruments , power generation equipment in some of the key components such as turbine blades typical , rotor and generator rotor slot trunking and other typical parts embedded processing and testing , so much the tool manufacturing industry 's attention. " Figuratively , CNC machine tool CNC teeth, precision measuring instruments is a CNC machine 's eyes. They promote each other , closely related , equipment, services, and promote the development of CNC manufacturing equipment , especially digital cutting technology ." Chengdu Tool Research the engineer, doctoral tutor so hit analogy .     Director of the National Engineering Research Center of precision tools , Chengdu Tool Research Institute, said that so far , the results in the center of the new tool material, tool material surface modification processes, measuring instruments and other aspects of the gear has been the leading domestic level . Through unremitting efforts, now has the most advanced , precision tools with independent intellectual property rights of production equipment , the establishment of the industrial base , making China in the development of precision tools , industrial process equipment and overall ability to achieve leapfrog development , some results have been close to or reach the world advanced level. The successful development of China has changed in the field of long-term dependence on imports . Responsible person said proudly: " The instrument features a number of technologies to break the blockade of foreign countries, detection resolution of 0.02 micron , length up to 20 meters to detect much lower price than similar foreign products in the international arena , this instrument . Britain and other countries with similar products in a summary level ! " " frequency laser interferometer , " is the central core of self-developed products, and now only the center of the country will also have the technology to produce this equipment.     Measuring meter pivotal , among precision instrument commissioning National Precision Tools Engineering Research Center , the staff tap the button , mounted on a testing platform for automotive gears quickly turn up on the computer screen next to the figures quickly beating. Just a few more than 10 seconds, the measurement results will be displayed, as well as the measured values ​​and tolerance values ​​next to people at a glance . Chao , deputy chief engineer of the Research Center for just these units successfully developed its own rapid detection sorter is this assessment : "Because detection speed, high degree of automation , coupled with low prices to meet the car manufacturers to achieve rapid detection gear hundred percent to ensure the quality and safety of the national car. this device fills the gap line detection and sorting technologies within the domestic automotive gear .
