3, 1 Refer to JH2G70 Section 1. Install the level. The level is placed on the joint block, passing through the center of the worktable, with the level placed on the level? Position, it is in the middle position of the upper worktable. The vertical and horizontal readings of the level meter are not more than 4/1000: 3.2 During the inspection, the inspection tools and inspection methods can be generally used according to the requirements of the inspection items. 3.3 During the inspection of workpiece analysis, the test piece should be inspected after fine turning. 3.4 When the actual measured length is different from the actual length specified in this standard, it can be calculated according to the provisions of Article 2.3.1.1 of JB2570. The length of the measured plate can be converted. When the converted result is less than 0.00:mm, it can still be connected to 0.0051mml:3.! When checking geometric accuracy, the workbench refers to the following: 3.6 The direction parallel to the case is the intended direction, the direction parallel to the beam is the horizontal space, 3.7 The vertical surface of the guide frame is called the horizontal plane, and the vertical surfaces perpendicular to the horizontal plane are called the transverse plane.
