ISO 2934:1973

Overview

ISO 2934:1973 is an international standard that defines the dimensional specifications for wing bases used in machine tool construction, specifically for columns in special purpose machines made from modular units. Developed by ISO Technical Committee ISO/TC 39 on machine tools, this standard ensures the interchangeability of wing bases, promoting modularity and compatibility across different manufacturers and machine configurations. The standard addresses critical dimensions that correspond to the nominal width of the saddle on associated slide units, referenced in ISO 2562.

Key Topics

• Modular Units for Machine Tools: Supports modular construction by standardizing elements such as wing bases and columns.
• Wing Base Dimensions: Specifies the key measurements to guarantee interchangeability, including bolt hole positions, flange width, base dimensions, and overall length.
• Nominal Sizes: Defines five nominal sizes for wing bases corresponding to saddle widths of slide units-250, 320, 400, 500, and 630 millimeters.
• Compatibility and Interchangeability: Wing bases designed per ISO 2934 can be reliably used with the related slide units specified in ISO 2562, ensuring system compatibility.
• Technical Details: Includes specific tolerances, bolt hole dimensions, clearance holes, and flange configurations critical for assembly and mounting.

Applications

ISO 2934:1973 is essential for industries involved in the design, manufacturing, and assembly of machine tools, particularly those utilizing special purpose machines constructed from modular components. Practical applications include:

• Designing modular machine tool frames where columns require standardized wing bases for secure and interchangeable mounting.
• Manufacturing slide units and columns that must conform to a consistent set of dimensional standards for ease of integration.
• Facilitating maintenance and upgrades by allowing replacement wing bases without custom modifications.
• Enhancing international trade and collaboration by providing a common basis for machine tool components across different markets.
• Supporting automation and precision machining tools that rely on modular, adaptable structural elements.

Related Standards

To ensure full compatibility and system integrity, ISO 2934:1973 should be used alongside the following related ISO standards:

• ISO 2562: Modular units for machine tool construction-Slide units. This standard defines the saddle widths that determine the nominal size of wing bases.
• ISO 2769: Wing bases for slide units, detailing dimensions for wing bases used specifically with slide units.
• Other ISO standards on machine tool components and modular constructions, supporting broader principles of machine tool interchangeability and modularity.

Summary

ISO 2934:1973 plays a vital role in enhancing the modular construction of machine tools by standardizing wing base dimensions for columns. It promotes effective interchangeability, reducing costs and complexity in machine design, manufacturing, and maintenance. Adherence to this standard ensures components fit seamlessly, supporting global industrial practices and advancing precision engineering in special purpose machinery.
