Overview

ISO 3476:1975 is an international standard developed by the International Organization for Standardization (ISO) focused on modular units for machine tool construction. Specifically, it specifies the dimensions of tenon drives and flanges used for mounting multi-spindle heads. These components are designed to fit on quill feed units and quill feed units with adjusting slides, facilitating efficient tool changing in machine tools. By standardizing these dimensions, ISO 3476 promotes interoperability, simplifies assembly, and enhances the modularity of machine tool systems.

Key Topics

• Tenon Drive Dimensions
  The standard defines exact measurements for tenon drives, including nominal drive shaft diameter, spigot diameter, and drive tenon width and length. This ensures compatibility across different machine tool modules.

• Mounting Flanges
  Dimensions for mounting flanges are specified to accommodate multi-spindle heads securely on various quill feed units. Specifications include pitch circle diameters and clearance holes tailored for specific bolt sizes.

• Modular Units Compatibility
  The standard applies primarily to two modular units:

  • Quill feed units
  • Quill feed units with adjusting slides for tool changing

• Dimensional Coordination
  ISO 3476 provides standardized dimensions to achieve uniformity in modular machine tool components, making the manufacturing process more streamlined and reducing the need for custom parts.

• Applicable Bolt Sizes
  The table of dimensions includes recommendations for the size of bolts (M8, M10) suitable for mounting, ensuring mechanical stability and ease of assembly.

Applications

ISO 3476:1975 is essential in the design and manufacture of machine tools that require modularity and easy interchangeability of spindle heads. Typical applications include:

• Multi-Spindle Machine Tools
  Facilitates the mounting of multi-spindle heads with precise tenon drives and flanges, optimizing productivity in high-volume machining operations.

• Tool Changing Systems
  The standard supports quill feed units equipped with adjusting slides, enabling quick and accurate tool changes, thus reducing machine downtime.

• Machine Tool Manufacturing
  Manufacturers can design and produce modular components based on ISO 3476 to ensure compatibility across a wide range of machines and systems globally.

• Machine Repair and Retrofitting
  Standardized dimensions allow for easier replacement of parts and upgrades, contributing to machine longevity and operational efficiency.

Related Standards

• ISO 3590: Modular units for machine tool construction – Spindle units
  Complements ISO 3476 by covering dimensions and specifications related to spindle units, ensuring cohesive design and function within modular machine tools.

• ISO 8020: Machine tools – Module system
  Provides broader guidelines on module systems that integrate components like those standardized in ISO 3476.

• ISO 529: Machine tool spindle noses – Dimensions and designations
  Relevant for detailed specifications when working alongside tenon drives and mounting flanges.

Summary

ISO 3476:1975 establishes critical dimension specifications for tenon drives and mounting flanges used in modular machine tool construction. By standardizing these components for multi-spindle heads on quill feed units, the standard enhances modularity, compatibility, and precision in machine tool design. It benefits manufacturers, machine operators, and maintenance teams by promoting efficient assembly, maintenance, and tool changing. Adherence to this standard helps reduce custom engineering, improve interoperability, and supports the global market of machine tool technologies.

FOREWORD
ISO (the International Organization for Standardization) is a worldwide federation
of national Standards institutes (ISO Member Bodies). The work of developing
International Standards is carried out through ISO Technical Committees. Every
Member Body interested in a subject for which a Technical Committee has been set
up 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.
Draft International Standards adopted by the Technical Committees are circulated
to the Member Bodies for approval before their acceptance as International
Standards by the ISO Council.
International Standard ISO 3476 was drawn up by Technical Committee
ISO/TC 39, Machine tools, and circulated to the Member Bodies in June 1974.
