Precision machining manufacturing needs not only the precision of the machine tool, the stability and the precision of the cutting tool, jig, to ensure that the same need to calibration, measurement precision measuring instrument.
Precision tooling engineering research center in the country between precision instrument debugging, the staff with the click of a button, on a testing platform of automobile gear spun up, next to on a computer screen, digital in beating quickly. A short span of more than 10 seconds, measured results is displayed, along with measured values and allowable deviation value, let a person be clear at a glance. The research center deputy chief engineer ChaoGang rapid detection of the platform to develop successful separator is said: "because the testing speed, high degree of automation, coupled with low prices, to meet the auto makers to realize rapid detection of gear one hundred percent, ensure the quality of the national automobile safety. The equipment filled in the domestic automobile gear the blank in the field of on-line detection and separation technology."
"Vividly metaphor, CNC cutting tools is teeth of nc machine tools, precision measuring instruments is the eye of the nc machine tools. They promote each other, is closely linked, equipment manufacturing, services, and promote the numerical control equipment, especially the development of digital cutting technology." Chengdu tool research institute, senior engineer, doctoral supervisor takeda kun that make the example.
Relevant statistics show that the measuring tool industry in our country after decades of construction and development, has initially formed relatively complete product categories, has a certain scale of production and development capabilities of industry system, become the outside Japan the world's second largest producer of measuring tool. But, as the basis of nc cutting technology, tool manufacturing industry in our country in the technical level and quality of performance of a measuring instrument, etc., with foreign advanced level there is still a large gap.
Domestic measuring tool window
From visual to simple measurement and precision measurement, the measurement technology progress to some extent, guarantee the progress of the manufacturing technology. Famous scientist qian xuesen Mr Also has pointed out: "information technology includes measurement technology, computer technology and communication technology. Measurement technology is the key and foundation."
Precision machining manufacturing needs not only the precision of the machine tool, the stability and the precision of the cutting tool, jig, to ensure that the same need to calibration, measurement precision measuring instrument. "Have a plenty of in the process of processing (such as the knife); some after the event detection (e.g., gear measuring instrument)."
, according to industry experts in wind power industry, for example, some typical key components in the power generation equipment such as turbine blade, the rotor wheel groove and the steam turbine generator rotor embedded trough the typical parts processing and testing, to a certain extent, represent and reflect a country's advanced cutting technology and CNC cutting tools, digital measurement technology and the latest achievements of a measuring instrument and level, and thus has become something of an tool manufacturing industry.
Feel's delight, the domestic measuring instrument manufacturing enterprise in digital display technology and digital display measuring tool products in recent years on the independent development of increasing investment, has made great achievements. Domestic digital display measuring tool in previous years a simple bar in front of the LCD digital display progress to more complex form LCD dynamic simulation of the image display, digital display caliper, let the resolution of the grid from 0.01 mm to 0.01 mm, the accuracy and reliability of the measurement have significantly improved. Constantly improve the performance of water-proof and dust-proof (from IP54 to IP65, has can reach IP67), also enhances the market competition ability of domestic digital display measuring tool.
Harbin measuring tool cutting tool group co., LTD. (hereinafter referred to as ha) in recent 10 years continuously strengthen the gear measuring instrument, the surface roughness measuring instrument and the profile measuring instrument such as precision instrument development and manufacturing advantages, successfully developed the current domestic biggest 2 meters CNC gear measuring instrument, become the most competitive domestic precision measuring instrument manufacturer.
National precision tool engineering research center director, director of the institute, chengdu tool Luo Defu said, so far, the center in the new cutting tool material, cutting tool material surface modification technology, the results of the gear instrument has been in the domestic leading level.
Through unremitting efforts, now has the most advanced, with independent intellectual property rights of precision tooling production equipment, set up industrialization base, make China precision tool in research and development, process equipment and industrialization ability overall realized leap-forward development, some results are close to or reached the world advanced level.
Dual-frequency laser interferometer is developed at the centre of the core product, now also only has the technology to the center, to produce the equipment. It changed the successful development of the situation of China in the field of the long-term dependence on imports. ChaoGang proudly said: "many function of the instrument to break the foreign technology blockade, detecting resolution of 0.02 micrometers, test length of 20 meters. Prices are much lower than those of similar foreign products, internationally, this instrument can be level with similar products from countries such as Britain and America!"
