S195柴油机曲轴的连杆轴颈的开档尺寸为38~(+0.10)mm,主轴颈之间开档尺寸为100±0.075mm,是曲轴的关键尺寸。我厂使用MQ8240磨床进行粗、精磨加工,长期存在尺寸难控制问题。 85年7月,我厂在6台MQ8240磨床上安装了6套SF2直线感应同步器数显装置(精度为±5μm),实现了曲轴开档磨加工自动过程测量,数字显示。经过一年连续使用(两班制),取得良好的技术经济效果。
S195 diesel engine crankshaft connecting rod shaft opening size is 38 ~ (+0.10) mm, the main journal between the opening size of 100 ± 0.075mm, is the key size of the crankshaft. I plant using MQ8240 grinder for coarse, fine grinding, the size of the long-term existence of difficult control problems. In July of 1985, our factory installed 6 sets of SF2 linear induction synchronizers digital display (accuracy: ± 5μm) on 6 MQ8240 grinding machines to realize the automatic process measurement and digital display of crankshaft open mill processing. After a year of continuous use (two shifts), achieved good technical and economic results.
