Precision Inspection of Heavy Rotary Tables
This standard specifies the requirements and inspection methods for the pre-adjustment and inspection of heavy rotary tables: JE18U3.2-1949
This standard is not applicable to 1. General-purpose rotary tables with a width of 0-3150mm or more. 2. Reference Standard
The following provisions are included in this standard: All provisions are cited in this standard and constitute this standard: At the time of publication of this standard, the latest version is valid: All Standards will be revised. The latest versions of the following standards may be used when this standard is used. B1741.1-8 General rules for bed inspection Part 3: General requirements for the intervals between goods or special conditions || tt || 3.1 This standard shall be used in accordance with GB1742: 3.2 The installation, inspection methods and inspection accuracy of the bed shall be in accordance with GB [17421.1--1998-3.! Adjust the bed guide to the level. At both ends of the bed guide, pay attention to the direction of the withdrawal when the level instrument: the horizontal and horizontal stains are not in the part of this 0.04/0003.3 Inspection items The schematic diagram drawn in the ruler is a guide rail, such as a square guide rail. If the guide rail is square, then the point of reference shall be discussed. 3.4 The accuracy test sequence listed in this standard does not represent the actual test sequence. For the convenience of assembly and disassembly test, the test sequence can be as follows: 3.5 When the actual length and width are different from the calibrated length, the difference should be reported to RT17431.119991.23.1.1. The calculated result should be less than 0.25mm or 0.0025mm. Approved by the State Administration of Machinery Industry on May 20, 1999. Implementation on November 1, 2000. HT86031199. ZzIts'zE 'IE
