This standard is for G155900.1-85 machine type two-way clamp shaft and faceplate relative connection dimension A type, when the rubber is set, it is equivalent to the national music standard 10702/1177 machine end - spindle and faceplate interchangeable external dimensions - Part 1, A: in terms of technical content, its basic wood is consistent, the format is the same as G1.194, when the standard is set, it is also specially! International standard IS702【:1F machine - shaft and faceplate
, the original standard section is explained
The main differences between this standard and TS72【:
1. Supplement the angle tolerance of the shaft and faceplate short group 3\. 3. Add the "?" standard for interchangeability of the belt and faceplate: interchangeable dimensions - Part 1: A type, etc. 3. Add the table of connection between the main and auxiliary ends and the faceplate. 1. Change the effective size of the main shaft end connection number and the size of the faceplate. 5. This standard only adopts the metric structural dimensions in 10702/1:1$?5. The metric and American clamp shaft ends and faceplate connections are interchangeable. This standard includes the following three parts under the general title of interchangeable dimensions of machine tool clamp parts and faceplates: Part 1 GB/T59HI,1A type: Part 2 GB/T5900.2 Chain type Part 3 GB/T5900.3 Bayonet type: Appendix A of this standard is an appendix to the standard. Appendix H of this standard is an appendix to the standard. The production standard shall be replaced by GB5300 from the date of its entry into force. 86g machine tool flange type shaft and faceplate interchangeable size small A type 3. This standard is proposed by the Ministry of Machinery Industry of the People's Republic of China. The Beijing Machine Tool Research Institute of the Ministry of Machinery Industry is busy with this standard. The Ministry of Machinery Industry, the Chemical Machinery Research Institute, the Yangzhou Automobile Health Research Institute, etc. GB/T5900.11997
ISO (International Organization for Standardization) is a world standard for national standards! ISO is a federation of international standards bodies. The work of developing international standards is done through technical committees. Each member body has a voice in the development of a technical committee. ISO is an international organization with a joint membership. Official and non-governmental organizations also have a role in the development of international standards. A draft international standard accepted by a technical committee must be reviewed by each member body before it is adopted as an international standard by the ISO Council. Before [?2], the research results of a technical committee are published as a recommended standard. This document is formally incorporated into the ISO standard. As part of this process, ISO13 reviewed ISO recommended standard R70 and recognized it as suitable for transformation into an international standard. However, it is divided into two parts. Therefore, the international standard 150702/1 (together with 50702/1) replaced the technically interchangeable I50 recommended standard R70%-968 down to the mature standard R702 Belgium, Chile, Czech Republic, Austria, France, Germany, Gambia, India, Israel, Morocco, Japan, Poland, South Africa, Spain, Denmark, Germany, Turkey, the United Kingdom, the United States and the Soviet Union. None of the member states disagreed with this recommendation. The following member states did not agree with the conversion of IS)/R?02 into an international standard: British area
