This standard specifies the 7:24 taper dimensions for toolholders and devices for spindle ends and manual tool change. This standard also specifies the flange outer diameter of these toolholders and devices, and the position of the flange face relative to the taper when connected with the front face of the flange. This standard applies to various types of machine tools and devices with a 7:24 taper connection for the spindle end and the corresponding toolholder. The taper dimensions of automatic tool changer toolholders are specified in GB/T 10944.

This standard is a revision of the previous standard (13537.1-5637.3193.1. Machine protection tools7:21-2003). This standard is equivalent to the standard 150297:199857134 manual tool change tool handle. 3. This standard has three main differences from IS0227:3988: 1) The same type of tool is used for tools with standard operating distance. Therefore, Chapter 3 "Interchangeability" of IS0297.1S88 ([6>, Table 3b) and the related permissions are cancelled in this standard. 2) In the structure diagram of the medical tank, the number "" is changed to e, and the following processing requirements are added. This standard is different from (13/T3837.1~8857.8—19%3) in the following main aspects: 1) The sub-standard of the original proposal is combined into one standard, and the standard name is changed to 7:4. The manual tool change tool handle needs to be changed. 2) The technical differences with the original standard are large (some numbers have been changed, but in order to ensure the quality of the tool, the requirements are changed): 188. 4) The classification of the main shaft end chain tool handle A type and the mouth type is cancelled. The parallelism and trueness requirements of the end face key are cancelled. This standard is effective from the date of the standard. The current standard is 1/3837.1~3837.31583. This standard is issued by the China Machinery Industry Federation. This standard is issued by the China Metallurgical Machinery Industry Association. This standard was first issued in June 1983. 3837207
ISO Foreword
ISO (International Organization for Standardization) is a federation of national standardization bodies (ISO members). International standards are usually prepared by technical committees. Each ISO member interested in a topic established by a technical committee has the right to express its opinion in that technical committee. International organizations, official or unofficial organizations related to ISO also participate in the work of preparing international standards. ISO cooperates closely with the International Electrotechnical Commission (IEC) on all matters related to the development of international standards. The draft international standard accepted by the technical committee shall be sent to the production department for discussion and voting. Publication as an international standard requires at least 5 votes or negative votes. International Standard [S0297] was prepared by the Technical Committee of the National Standards Committee (190)/TC29 for Machine Tools. The first edition replaces the first edition (IS) 2,1582 and IS 2,5831972) and has been technically modified. 1 Scope

This standard specifies the dimensions of the spindle end and the manual changer and the tool and the tool. ·2 Net size: This standard also specifies the outer diameter of these tools and devices, as well as the position of the surface relative to the return when the front is connected. The two convex and green sides of the machine tool are used to turn the axis of the main and auxiliary parts of the machine tool. The connection between the two tools and the main racket can be realized by the rear clamping method of the tool handle fastening screws, or by the main racket of the machine tool being arranged on the flange to realize the connection. The tool or device can be removed from the main shaft. Only when the tool or device is removed, the position of the convex front surface relative to the diameter of the corresponding tool holder is specified. It is suitable for various types of machines and equipment with 7, 24-surface auxiliary connections at the main shaft end and the corresponding tool handle. The dimensions of the tool holder for automatic tool change are specified in (GB/1091-2, 2 referenced standards || tt || The texts contained in the following standards constitute the provisions of this standard through reference in this standard: When the standard version is shown, the version shown is valid, all the standard tapes will be marked, and the parties using this standard should use the latest version of the following standards: G120 inner big angle column head (gIS4762.1157 GB/T0944-198S automatic tool change machine tool 7:24 processing only Tong 40.45 and 50 hungry handle (neg1s 7na-1t93)
