导轨防护装置是机床或仪器不可缺少的部分,它防护性能的好坏将直接影响机械的精度和寿命。我厂为数控机床配套生产的刀具预调仪,要求拖板具有移动均匀、运动灵敏及定位精度高等特点,故采用滚珠式导轨。而滚珠导轨对脏物比较敏感,因此必须选用良好的防护装置。我厂选用了钢带式防护装置,它的密封性能较好, Rail protection device is an indispensable part of the machine tool or instrument, its protective performance will directly affect the accuracy and life of machinery. I plant for the production of CNC machine tools tool presetter, drag plate requires moving uniform, sensitive and positioning accuracy of high-speed characteristics, so the use of ball-type guide. The ball guide is more sensitive to dirt, so you must choose a good protective device. I used the factory-strip protection, its sealing performance is better,
