Overview
ISO 702-4:2004 (Machine tools - Connecting dimensions of spindle noses and work holding chucks - Part 4: Cylindrical connection) specifies the sizes required for interchangeability between cylindrical spindle noses and the corresponding connecting faces of face plates or work holding chucks. This part of ISO 702 defines dimensional references, hole patterns and designation conventions used by manufacturers and machine shops to ensure compatible, repeatable workholding.
The standard was prepared by ISO/TC 39 (Machine tools), Subcommittee SC 8 (Work holding spindles and chucks) and forms part of the multi-part ISO 702 series covering conical, camlock, bayonet and cylindrical connections.
Key Topics
- Scope and purpose: Establishes sizes for interchangeability of cylindrical connections on spindle noses and matching chucks/face plates.
- Size range: Dimensions and interchange data are provided for size numbers specified in the standard (reference sizes No. 3 to No. 28), with nominal diameters and detailed dimension tables.
- Bolt circle and hole patterns: The standard addresses a single bolt circle per spindle nose, specifying the number of holes (for example, 6 holes for Size No. 3 and 12 holes for Sizes No. 4 to No. 28) and requirements so that the chuck pitch is a multiple of 30° to match spindle holes.
- Connecting-face details: Tables and figures show the required mating-face dimensions for face plates and work holding chucks to ensure correct fit and function.
- Designation: A cylindrical connection is designated by the part number and nominal size (for example, ISO 702-4 - No. 8).
Applications
- Retrofit and replacement of chucks, face plates and spindle-mounted accessories without custom rework.
- Standardized manufacturing of spindles and workholding equipment to ease supply-chain compatibility.
- Maintenance planning and parts procurement for machine shops and production facilities.
- Design of new machine tools where consistent, repeatable mounting and interchangeability of tools and chucks are required.
Benefits include reduced downtime, simplified inventory of spare parts, improved interchangeability across equipment from different manufacturers, and clearer specification for suppliers and OEMs.

- ISO 702-2 - Camlock type
- ISO 702-3 - Bayonet type
Note: ISO 702-4:2004 includes figures and tables that give exact dimensions and tolerances for each size. Users should consult the full published standard for precise numeric data and implementation details, and be aware of any applicable patents or national adaptations before production or procurement.

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, Part 2.
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 document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.

Avant-propos
L'ISO (Organisation internationale de normalisation) est une fédération mondiale d'organismes nationaux de
normalisation (comités membres de l'ISO). L'élaboration des Normes internationales est en général confiée
aux comités techniques de l'ISO. Chaque comité membre intéressé par une étude a le droit de faire partie du
comité technique créé à cet effet. Les organisations internationales, gouvernementales et non
gouvernementales, en liaison avec l'ISO participent également aux travaux. L'ISO collabore étroitement avec
la Commission électrotechnique internationale (CEI) en ce qui concerne la normalisation électrotechnique.
Les Normes internationales sont rédigées conformément aux règles données dans les Directives ISO/CEI,
Partie 2.
La tâche principale des comités techniques est d'élaborer les Normes internationales. Les projets de Normes
internationales adoptés par les comités techniques sont soumis aux comités membres pour vote. Leur
publication comme Normes internationales requiert l'approbation de 75 % au moins des comités membres
votants.
