瑞士L.克伦贝格(L.Kellenberger)公司的R175×1500型精密外圆磨床是上海第二纺织机械厂1980年进口的机床,安装在临时性空调恒温室内。为摸清该机床的质量和技术性能,找出国产机床与它的差距,以进一步发展我国的高精度外圆磨床,我们于1980年11月去该厂对此机床作了动态性能的测试与分析。由于测试仪器的限制,仅对机床的空运转作了振幅测量,对整机作了相对激振试验。机床安置在垫铁上,并在测试前按机床使用说明书规定予以调整,使各项指标均达到规定要
The R175 × 1500 Precision Cylindrical Grinder from L. Kellenberger in Switzerland is a machine tool imported by Shanghai No.2 Textile Machinery Factory in 1980 and is installed in a temporary air-conditioned thermostatic chamber. To find out the quality and technical performance of the machine tool to find the gap between domestic machine tools and to further develop our country’s high-precision cylindrical grinder, we went to the factory in November 1980 for this machine made a dynamic performance test and analysis. Due to the limitation of the test equipment, the amplitude measurement was made only on the air transportation of the machine tool, and the relative excitation test was carried out on the whole machine. Machine placed in the horn, and in accordance with the machine manual before the test to be adjusted so that the indicators have reached the required
