The granite parallel ruler does not need to worry about deformation due to temperature changes, does not appear scratches, is not disturbed by constant temperature conditions, and can maintain the accuracy of temperature measurement at room temperature
specification and accuracy of granite parallel ruler: 500 × one hundred × 40,750 × one hundred × 40,1000 × one hundred and twenty × 40,1500 × one hundred and fifty × 60,2000 × two hundred × 80,3000 × two hundred × 80。 The accuracy is divided into two levels: 00 and 0
granite parallel ruler is mainly used in machine tool assembly, straightness measurement of guide rail and flatness inspection of plane
use of granite parallel ruler: the rock ruler is mainly used for grinding and scraping processes on the working face, and is used to check the unevenness and straightness in the inspection of machine tools.; The granite parallel ruler can be matched with a square to test the verticality of two machine parts that cannot be tested only with a square; The granite ruler is also suitable for equipment installation and inspection, and the service temperature is (20 ± 5) ℃
the granite parallel ruler does not need to be oiled during use. It has good hardness and is easy to use
place the granite parallel ruler on the inspection plate, and measure the height difference of no less than three places on its working surface with a dial indicator equipped with a division value of 0.001mm, which is the parallelism error
when there is no applicable inspection plate, it is allowed to place the side of the ruler on a bearing surface and measure the height difference of the ruler with a lever micrometer with an index value of 0.002mm or a gauge with an index value of 0.002mm
