subject: Import Substitutiongrinding Machine [print this page] April 22, from Sichuan Yibin Push-driven company completely independent research and development and production of high-speed railway track board dedicated CNC grinding unit in charge by the Ministry of Railways and the China Railway Joint acceptance of the sixth inning. It is reported that the success of the device R & D and production, to break the monopoly of the German long-term dedicated high-speed railway in China market, the pattern of CNC grinding machines.
In fact, before East and successfully developed the NC High Speed Railwys Borg board dedicated CNC gantry rail-grinder.
Another example is Electronic Enterprise Co., Ltd. Nanjing quarto successfully developed jointly with Tsinghua University, five-axis laser machining Wire edm machine, to break the blockade of foreign technology to solve high-precision manufacturing of the core technology of radar problems. The Wire edm machine appeared in the Shanghai Industrial Exhibition, held in 2009 in China.
"It's machining accuracy of -class, the equivalent of hair 1 / 70. It is the biggest highlight of the five-axis CNC and optical fiber laser." According to the company's technical personnel, only the cash register that sets the size of the Wire edm machine also high precision can be processed in the heart stents and other medical equipment, aerospace, medical and other fields to show off their capabilities.
In the high-precision radar development, the need for a core of micro-devices?? Processed by the metal molybdenum, only 12 mm diameter sphere grid, grid ladder in 72 small cell, small cell connected between the "bar" only 0.12 mm.
