我厂在上海机床研究所的配合下,在一台T68型卧式镗床上安装了三坐标国产磁栅数显装置。通过生产验证,镗孔孔距误差可达到0.01～0.02mm,效果很好。上海机床研究所研制的微机磁栅数显仪,有数年的生产历史,已投入小批量生产。该研究所还制造与数显仪配套的磁栅尺。他们研制的磁栅数显技术,接近于日本索尼公司的水平,在国内处于领先地位。目前,国内磁栅生产能力较低,使用正在逐步发展。
I plant in cooperation with the Shanghai Institute of Machine Tools, in a T68 horizontal boring machine installed three-coordinate grid-made digital display device. Through the production verification, boring hole pitch error can reach 0.01 ~ 0.02mm, the effect is very good. Shanghai Institute of Machine Tools developed computer magnetic digital display, a few years of production history, has been put into small batch production. The institute also manufactures magnetic scale for digital display. They developed the digital grille technology, close to the level of Japan’s Sony Corporation, a leading position in the country. At present, the domestic magnetic grid production capacity is low, the use is gradually developing.
