Not applicable to single-blade hydraulic circular saw machines with saw blade diameter less than or equal to 5mml (hereinafter referred to as machine tools) Reference Standards
The following provisions are included in the following special specifications, and the provisions of this standard are verified by citing in this standard. When this standard is published, the versions shown are valid: All standards will be revised, and the parties using this standard should explore the possibility of using the latest versions of the following standards, JB/T417t-1999 MMT machine tool precision inspection 3-Quality requirements
3.1 When using this standard, JBT4I should be cited. 3.1 Refer to 3.1 of JB4171-1999, adjust the installation level of the machine tool, place the level in the center of the work surface, and the level reading should not exceed 0.101000
3.3 The order of the error grid items listed in the standard does not represent the actual inspection order. In order to improve efficiency, inspection can be carried out in any order. 3.4 When the assumed length measurement cannot be controlled, the tolerance can be based on JB/T417! ··19993.2.1.1 stipulates that the length of the measuring plate can be converted, and the minimum conversion value is 0.0tmm
