With the continuous emergence of various technologies in front of us, and CNC machining is one of them. We all know that it is a relatively common technology in the industry, and it is also a more common technology that we use. What is the precision detection of CNC machining?
CNC machinist CNC lathe for different shape of guide rail, each surface should control which plane straightness error?
In CNC machining, scraping and lapping method is used to trim the straight line of guide rail to pass the lost time. The method of grinding point is often used in the inspection of short guide rail. Because of the simple deformation when the leveling ruler exceeds 2000mm, it is difficult to manufacture and affects the measurement accuracy. When scraping and grinding the short guide rail.
The straightness error of guide rail is usually ensured by the accuracy of the leveling ruler, and the density of lapping points per unit area is also determined. According to the accuracy requirements in the middle of processing and the nature and important level of the guide rail in the middle of the processing, the rules are as follows: no less than 10 ~ 20 points per 25 mm × 25 mm internal lapping points (i.e. the number of points in each scraping Square).
The common shapes of CNC machining intermediate guide rail are rectangular guide rail and V-shaped guide rail. The degree surface of the rectangular guide controls the straightness error of the guide in the pen plane. The error of straightness in the degree plane is controlled by two or four sides of rectangular guide rail. For the V-shaped guide rail, the two inclined surfaces not only control the straightness error in the straight plane, but also control the straightness error in the degree plane.
