ISO 12164-4:2023

Overview

ISO 12164-4:2023 is an international standard that defines the dimensional and design specifications for receivers with taper and flange contact surfaces for hollow taper shanks (HSK). This standard focuses on receivers of type T (for automatic tool changes) and type U (for manual tool changes), suitable for use in machine tools, particularly turning machines and combination turning and milling machines. The receivers described in this document are designed to interface with HSK shanks of types T, TA, and U, as specified in ISO 12164-3, as well as shanks of types A, AB, C, and CB from ISO 12164-1.

By standardizing receiver dimensions and their applications, ISO 12164-4:2023 ensures interoperability, reliability, and safety in machine tool operations worldwide.

Key Topics

• Receiver Types:

  • Type T Receivers: Designed for automatic tool change systems.
  • Type U Receivers: Intended for manual tool changes using radial holes in both receiver and shank.

• Compatibility:

  • Receivers of types T and U are compatible with HSK shanks T, TA, and U (ISO 12164-3), as well as A, AB, C, and CB types (ISO 12164-1).
  • HSK shanks A, AB, C, CB, T, and TA may also be manually changed.

• Dimensional Specifications:

  • Detailed tables provide standardized dimensions for all critical interface features.
  • Tolerances conform to general ISO standards (ISO 1101, ISO 3040, ISO 2768-1).

• Material and Hardness Requirements:

  • Receivers must be manufactured from suitable steel, achieving high surface hardness (minimum 60 HRC) and robust core strength to withstand operational demands.

• Designation System:

  • Standardized designation format simplifies specification and procurement (e.g., "Receiver ISO 12164-4 - HSK-T 63").

Applications

The ISO 12164-4:2023 standard is widely used in:

• Machine Tool Manufacturing:

  • Facilitates reliable interfacing between tool shanks and machine spindles, particularly for CNC lathes, machining centers, and multi-tasking machines.
  • Enhances flexibility and efficiency in automatic and manual tool changing operations.

• Industrial Automation:

  • Supports integration in automated tool changers, optimizing machine uptime and reducing setup times in high-volume production environments.

• Maintenance and Retrofitting:

  • Provides the guidelines needed for maintenance engineers to replace or retrofit machine tool receivers while ensuring compatibility and performance.

• Global Trade and Procurement:

  • Promotes international compatibility and quality assurance, easing equipment sourcing across markets.

• Precision and Productivity:

  • Ensures the accuracy of tool positioning and repeatability, which is critical for high-precision machining applications.
