The provisions contained in the following standards constitute the provisions of this standard through reference in this standard. When this standard is published, the versions shown are valid. All standards are subject to revision, and parties using this standard should explore the possibility of using the latest versions of the following standards. JB/T4171-1999 General Rules for Precision Inspection of Woodworking Machine Tools 3 General Requirements
3.1 When using this standard, refer to JB/T4171. 3.2 Refer to 3.1 in JB/T4171-1999 to adjust the installation level of the machine tool. Place the level in the center of the workbench. The level reading should not exceed 0.10/1000.
3.3 The order of precision inspection items listed in this standard does not represent the actual inspection order. In order to improve efficiency, inspections can be carried out in any order. 3.4 When the specified length cannot be measured, the tolerance can be converted according to the measurable length according to 3.2.1.1 in JB/T4171-1999, and the minimum conversion value is 0.01mm.
4 Geometric Precision
Geometric precision inspection shall be in accordance with the provisions of Table 1.

Insert the inspection rod into the guide column hole so that the end of the inspection rod touches the working surface of the lower die. Then use a feeler gauge to measure the gap between the end of the inspection rod and the working surface of the lower die along the circumferential direction. The maximum measured gap is the verticality
