This standard is based on [902773-11973 (confirmed in 1990) - Vertical Drilling Machine - Accuracy Inspection - Part 1, Geometric Determination of Degree of Correction.
This standard has made minor technical changes to IS277-11973 (confirmed in 1990). [502773-11973 confirmed in 1995) mentioned in G4 that "the straightness of the guide rail should be inspected". Taking into account the structural characteristics of my country's vertical drilling machine, the word "straightness of the guide rail" is used in this standard. The method of checking the verticality of the spindle shaft and the verticality of the guide rail at the upper and lower positions of its travel is used to check the verticality of the spindle shaft and the verticality of the guide rail.
G/T4018 is divided into two parts under the general title of precision inspection of measuring column filling stations. Part 1 G/T4918.1 Geometric precision inspection Part 2 GB/T4018.24 Working precision inspection>, which will take effect from the date of entry into force and replace the geometric inspection part of G/T4018-83. This standard was proposed by the Ministry of Machinery Industry of the People's Republic of China and was approved by the Beijing Institute of Analysis of the Ministry of Machinery Industry.

ISO Foreword
ISO (International Organization for Standardization) is a federation of national standardization bodies (150 member bodies) within the world scope. The formulation of international standards is completed through ISO technical committees. Each member who is interested in the topic of the established technical committee has the right to express his opinion at the meeting. Related international organizations, official and non-official organizations also participate in the formulation work. The draft international standard accepted by the technical committee must be voted on by each member before being determined as an international standard by the ISO Council
International Standard 1502773- 1 Drafted by 150 C39 Machine Tool Technical Committee and submitted to the member countries in June 1972, this standard has received the following approvals: Belgium, Austria, Ireland, Italy, New Zealand, Romania, Japan, Spain ... 1 Specification
This standard specifies the requirements and methods for the accuracy test of vertical drilling machines. This standard is applicable to general vertical drilling machines. 2 Referenced standards

JB267-82 Precision Inspection and Testing of Machine Tools 3 General Requirements
3.1 When using this standard, reference should be made to JB2670, especially the installation, idle operation, warm-up, inspection of the shaft and other parts before the precision inspection! The recommended inspection and testing tools are given in accordance with the recommended inspection and testing methods.
3.2 The geometric accuracy inspection is arranged in order according to the machine and tool parts, so it does not represent the actual inspection order. In order to make the installation and disassembly of the tools and the inspection methods more convenient, the inspection can be carried out in any order. 3.3 When the actual measured length is different from the length specified in this standard, the tolerance should be reported in accordance with the provisions of 2.3.1.1 of JB2670-82, and the length that can be measured should be converted. When the conversion result is less than 0.07mm, it is still calculated as 0.mm. 3.4 According to the structural characteristics or the agreement between the user and the manufacturer, the inspection items can be increased. 3.5 The working precision inspection of this machine tool will be specified in Part 2 of this standard. Approved by the State Administration of Technology Supervision on 1997-71-13 and implemented on 1998-07-01
