JE267 General rules for inspection of metallurgy and scratching machines 3 General requirements
3.1 Sign B2670 Article 3.1 Adjust the installation level of the machine tool, place a special bridge plate for metallurgy on the bed navigation, and place a spirit level on it. The level should only be within the range of D,M/1000 in both the longitudinal and lateral directions.3.1 During inspection, the actual inspection times can be arranged according to the inspection tools and the convenience of inspection, and the requirements of the heat inspection items. 3.3 When inspecting the working accuracy, the inspection of the test piece should be carried out after the vehicle is in operation. 3.4 When the actual length is different from the length specified in this standard, the tolerance should be converted according to the measurable length in accordance with the provisions of Article 2.3.1.1 of JH2670. When the conversion result is less than 0.005mm, the 0.005mm tolerance is still used. Approved by the Ministry of Industry on 1996-84-11
