ISO 5414-2:2002 平らな円筒シャンクツール用のクランプネジ付きツールチャック（エンドミルホルダー）—パート2：チャックの接続寸法と指定 | ページ 2

Foreword

ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.

International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, 3.

The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote.

Attention is drawn to the possibility that some of the elements of this part of ISO 5414 may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights.

ISO 5414-2 was prepared by Technical Committee ISO/TC 29, Small tools, Subcommittee SC 2, Drills, reamers, milling cutters and milling machine accessories.

This second edition cancels and replaces the first edition (ISO 5414-2:1982), which has been technically revised (in particular by the addition of shanks with diameters 14 mm and 18 mm, and of chucks with 7/24 taper shanks for automatic changers).

ISO 5414 consists of the following parts, under the general title Tool chucks (end mill holders) with clamp screws for flatted cylindrical shank tools:

• Part 1: Dimensions of the driving system of tool shanks
• Part 2: Connecting dimensions of chucks and designation

1 Scope

This part of ISO 5414 specifies the dimensions of tool chucks (end mill holders) with clamp screws for tools with flatted cylindrical shanks in accordance with ISO 3338-2. It also specifies the designations of these chucks.

Two types of connection are defined:

• chucks with 7/24 taper shanks in accordance with ISO 297 for manual changers and with ISO 7388-1 for automatic changers, for tool shanks with either single flat or a double flat for manual and automatic changers;

  NOTE 1 This part of ISO 5414 specifies the dimensions of tool chucks with 7/24 taper shanks No. 30 for automatic changers although these are not standardized.

• chucks with Morse taper shanks in accordance with ISO 296 and ISO 5413 for tool shanks with a single flat only.

  NOTE 2 The dimensions of the driving system of the tool shanks are dealt with in ISO 5414-1.
