1 Subject Content and Scope of Application
This standard specifies the requirements and inspection methods for the geometric accuracy and working accuracy of CNC vertical drilling machines. This standard applies to CNC vertical drilling machines with a maximum drilling diameter of less than or equal to 63mm. 2 Reference Standards
GB10931 Method for evaluating the position accuracy of digital controlled machine tools JB2670 General rules for precision inspection of metal cutting machine tools JB3051 Nomenclature of coordinates and movement directions of digital controlled machine tools 3 General Requirements
3.1 During inspection, the actual inspection sequence can generally be arranged according to the requirements of assembly and disassembly of inspection tools and convenience of inspection. 3.2 During the working accuracy inspection, the inspection of the test piece should be carried out after fine machining. JB/T 8357.1-96
3.3 When the measured length is different from the length specified in this standard, the tolerance shall be converted according to the measurable length in accordance with the provisions of 2.3.1.1 of JB2670. When the conversion result is less than 0.005mm, it shall still be calculated as 0.005mm. 3.4 The X, Y, and Z coordinate systems shall comply with the provisions of JB3051. 3.5 According to the agreement between the user and the manufacturer, the inspection items can be increased or decreased. 4
