The provisions of 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 will be revised quickly. All parties using this standard should consider the possibility of using the latest version of the following standards: (H/17421.1-1 State 8 Peach Machine Tool Test General Rules Part 3: Geometrical Accuracy of Machine Tools under No-load or Loading 3 General Requirements
3.1 When using this standard, the relevant provisions of CBT17421.1 should be followed. In particular, the installation of the spindle and other components before testing, the temperature rise during operation, the inspection method and the accuracy of the inspection tools. 3.2 The order of the accuracy inspection items listed in this standard does not indicate the actual order. In order to install and disassemble the inspection tools and the inspection force, any order can be used. 3.3 When the actual measured length is different from the length specified in the standard, the tolerance shall be converted according to the length that can be measured according to the provisions of 2.3.1.1 of B17421.1-18. When the conversion result is less than 0.001nmn, it shall still be calculated as 0.00m. 3.4 The longitudinal plane referred to in this standard is the vertical plane passing through the main axis (when the main axis is in a vertical state) and the vertical axis: the plane between the can and the vertical plane (when the test is in a vertical state) is the plane between the can and the vertical plane. 3.5 If there are special provisions in the "Test Method" column of Section 5 of this standard, the main axis should be in a zero position and tightened. 3.6 According to the agreement between the user and the manufacturer, the inspection items can be increased: Approved by the National Machinery Industry Bureau on May 20, 1999, implemented on January 1, 2000, JB/T98971999, 0001010, 3B/T9897-1999, 0001010, 3B/T9897-1999, 0001010, 3B/T9897-1999, 0001010, 3B/T9897-1999, 0001010, 3B/T9897-1999, 0001010, 3B/T9897-1999, 0001010, 3B/T9897-1999 9897-1999
