JB/T10165.1—1999
This standard is formulated based on the development of science and technology and market demand, and on the basis of meeting the requirements of users and summarizing production practices. When formulating this standard, reference was made to domestic and foreign standards such as JIS B6218—1990 "Test methods and inspections for single-spindle automatic lathes with movable headstock" and JB/T1464—1994 "Precision of single-spindle longitudinal cutting automatic lathes". This standard is part of JB/T10165 "CNC longitudinal cutting automatic lathes". This series of standards includes the following two parts: Part 1 (i.e. JB/T10165.1): Precision inspection of CNC longitudinal cutting automatic lathes; Part 2 (i.e. JB/T10165.2): Technical conditions for CNC longitudinal cutting automatic lathes. This standard was proposed by the National Technical Committee for Standardization of Metal Cutting Machine Tools. This standard is under the jurisdiction of Chengdu Instrument and Machine Tool Research Institute. The responsible drafting unit of this standard: Ningjiang Machine Tool Factory. The main drafters of this standard are Chen Yongming, Qian Wenming, Wang Guikang, Cai Puxun and Wang Hui. 172

The provisions contained in 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 are subject to revision, and parties using this standard should explore the possibility of using the latest versions of the following standards. GB/T17421.1-1998 General Rules for Machine Tool Inspection Part 1: Geometrical Accuracy of Machine Tools under No-load or Finishing Conditions GB/T17421.2-2000 General Rules for Machine Tool Inspection Part 2: Determination of Positioning Accuracy and Repeat Positioning Accuracy of CNC Axis 3 General Requirements
3.1 Adjust the installation level in accordance with 3.1 of GB/T17421.1-1998. A special bridge plate is placed on the guide rail of the bed, and a level gauge is placed on it. The readings of the level gauge in the longitudinal and transverse directions shall not exceed 0.04/1000. 3.2 During the inspection, the actual inspection sequence shall be arranged according to the requirements of the installation and disassembly inspection tools, inspection convenience, and thermal inspection items. 3.3 During the working accuracy inspection, the inspection of the test piece shall be carried out after finishing. 3.4 When the actual 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 GB/T17421.1-1998. When the conversion result is less than 0.005mm, it is still calculated as 0.005mm. 3.5 The plane determined by the tool tip and the spindle axis is called the main plane; the plane passing through the spindle axis and perpendicular to the main plane is called the secondary plane.
3.6 The movement direction of the machine tool coordinate axis is defined as the direction parallel to the spindle axis as the Z axis, and the direction perpendicular to the spindle axis as the X axis. 3.7 When inspecting the machine tool, it is not necessary to inspect all items in this standard according to the structural characteristics. When inspection is required for acceptance purposes, the user can obtain the manufacturer's consent to select some inspection items he is interested in, but these items must be clearly stated when ordering the machine tool. Approved by the State Bureau of Machinery Industry on October 8, 1999 and implemented on March 1, 2000
