"Wheel Lathe Precision Inspection" There is currently no international standard or foreign advanced standard. This standard is formulated with reference to the precision inspection sheet of portal wheel lathes of advanced foreign wheel lathe manufacturers. This standard is a part of JB/T10141 "Wheel Lathe". This series of standards includes the following two parts: Part 1 (i.e. JB/T10141.1): Wheel Lathe Precision Inspection; Part 2 (i.e. JB/T10141.2): Wheel Lathe Technical Conditions. This standard is proposed and managed by the National Technical Committee for Metal Cutting Machine Tool Standardization. The responsible drafting unit of this standard: Qinghai Heavy Machine Tool Factory. The participating drafting unit of this standard: Qiqihar First Machine Tool Factory. The main drafters of this standard: Wang Shijun, Wang Qing, Jiang Zhaofang, Chen Wei, Dong Jingqi. 1 Scope

2 Referenced standards
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 will be revised. The 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: Geometric Accuracy of Machine Tools under No-load or Finishing Conditions 3 General Requirements
3.1 Refer to 3.1 in GB/T17421.1-1998 to adjust the installation level. Place a level gauge at both ends of the machine tool bed, and the readings of the level gauge in the longitudinal and transverse directions shall not exceed 0.06/1000.
3.2 Pre-adjustment inspection is only carried out during assembly, and no re-inspection is performed after the load test. 3.3 During inspection, the actual inspection order can generally be arranged according to the requirements of assembly and disassembly inspection tools, inspection convenience, and thermal inspection items. 3.4 When the precision test is carried out, the test piece shall be tested after finishing. 3.5 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 GB/T17421.1-1998. When the conversion result is less than 0.005mm, it shall still be calculated as 0.005mm. 3.6 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. Approved by the State Bureau of Machinery Industry on October 8, 1999 and implemented on March 1, 2000
