How to check the distortion of the single guide surface?

How to check the distortion of the single guide surface? Shared by China High Spcnc lathe machine Manufucturer.

Answer: about the appearance of each guide rail shape, in addition to in the horizontal plane and the straight surface there are straightness requirements, in order to ensure that the guide rail and moving parts cooperate with outstanding, progressive touch rate, but also need to control the guide rail appearance distortion error, this demand for large guide rail is particularly important. In scraping, in order to measure the parallel between the guide rail error, as a benchmark measurement with the guide rail, but also to avoid severe distortion.

Single guide rail appearance distortion error inspection method: V type guide rail with V type level pad iron, flat guide rail pad iron, from the arbitrary end of the guide rail, moving the level pad iron, every 200 ~ 5001Am reading, the maximum algebraic difference of reading level, is the guide rail distortion error. The error requirements in the precision specification of the machine tool as a rule, the first rule in the scraping and grinding process.
