How to detect Perpendicularity Error between components by using right angle ruler drawing table

Release Time: 2018-05-16

It is more commonly used in machine tool repair to detect the perpendicularity error between parts with a right angle gauge, and the diagram shows the method of measuring the Perpendicularity Error of the sliding pillow in front table of the planer. The right angle ruler is fixed on the front surface to make the inspection plane and the ram move parallel. The indicator is fixed on the sleeper to make the head on the test face of the right angle ruler and move the sleeper within the specified length of the stroke. The maximum difference of the reading number of the indicator is the perpendicularity error. The error of a and B should be calculated separately in a vertical plane and B horizontal plane respectively.
