Overview
The ISO 2912:1973/Amd 1:1982 is an amendment to the international standard focused on modular units for machine tool construction, specifically addressing multi-spindle heads. This amendment updates the casing and input drive shaft dimensions to improve machine interoperability and precision. Developed by ISO Technical Committee ISO/TC 39 on machine tools, this amendment ensures the continued relevance of multi-spindle head components in modern industrial applications by providing revised specifications for critical design elements.
Published on June 1, 1982, this amendment replaces Figure 2 and Table 2 of the original ISO 2912:1973, offering updated dimensional data that impact the input drive shaft and the casing envelope of multi-spindle heads. Such updates aim to standardize these components, enhancing compatibility and interchangeability across various machine tool manufacturers.
Key Topics
- Multi-Spindle Heads: Specialized modular units in machine tools that allow simultaneous machining of multiple parts, increasing productivity.
- Input Drive Shaft Dimensions: Precise measurements for shafts transmitting power to multi-spindle heads, crucial for performance and integration.
- Casing Dimensions: Standardized external dimensions of the multi-spindle head casings to ensure fitting and alignment within the machine tool assembly.
- Interchangeability: Emphasis on standardization promotes compatibility between multi-spindle head components from different manufacturers.
- Dimensional Updates: The amendment revises Figure 2 and Table 2, providing essential dimensional parameters in millimeters for design and manufacturing.
Applications
The updated ISO 2912:1973/Amd 1:1982 standard is vital in the following areas:
