Precision Inspection of Plate Edge Planers
This standard stipulates the requirements and inspection methods for the geometric accuracy and working precision of plate edges, JR/T8770.1—1998
This standard is applicable to ordinary precision extreme plate edge planer machines with a length of 5000~1600cmm. 2 Referenced standards
The following standards contain common provisions, which become the system of this standard through reference in other standards. The version shown at the time of publication of this standard is the effective date: All standards will be revised from time to time. Parties that stop using this standard should consider the availability of the latest version of the following standards. B267-2 Jincheng official machine tool precision inspection wheel pass bar || tt || 3 General requirements || tt || 3.1 Cutting resistance TE2679-82 3.1 Adjust the installation water? , Put some small instruments in the longitudinal and transverse directions at both ends of the bed guide rails. Not only the longitudinal and transverse readings are not effective, but also the 5/1HU:32 inspection time-stock can be connected to the inspection work and the inspection force is injured. The actual order of the whole will be: 3.3 When the actual length is different from the length specified in this standard, the tolerance should be multiplied by the maximum length measured by the provisions of 2.3.1.1 of F260-82. When the result is less than p.o1mn, press o.cmm! 4 According to the agreement between production and manufacturing, the inspection items can be increased or decreased after reporting.
