Overview

ISO 26622-3:2026, titled Modular taper interface with ball track system - Part 3: Dimensions of shanks for interface utilizing four locking elements, defines the dimensional requirements for tapered shanks used in modular taper interfaces equipped with a ball track system and four locking elements. This standard is designed to enable both automatic and manual tool exchange for a wide range of machine tools, including lathes, drilling machines, milling machines, and turn/milling centers.

The standard ensures precise interoperability and repeatability in tool clamping systems, supporting high-performance and secure tool changes for modern manufacturing environments. Adopting ISO 26622-3:2026 promotes compatibility between tool shanks and receivers produced by different manufacturers.

Key Topics

Scope of Application
- Specifies dimensions for a range of modular tapered shank sizes with four locking elements
- Applicable to both automatic and manual tool exchange systems
- Integrates compatibility features such as grooves on the shank flange for automatic tool changers
Dimensional Specification
- Details linear and angular tolerances according to ISO 8015 and ISO 22081 for optimal fit and function
- Includes precise descriptions of the tapered hollow shank geometry and associated features for insertion, clamping, and ejection
Coolant Sealing
- Specifies requirements for the coolant tube and O-ring sealing details (Annex A and Annex B) to ensure effective lubrication and tool cooling
- Recommends high-quality sealing materials for improved durability and performance
Clamping Mechanism
- Defines the use of standard-size locking balls and compatible mechanisms to achieve optimal clamping force and secure interface
- Addresses balancing and strength requirements to support high-speed and high-torque applications
Design and Material Considerations
- Provides recommendations for the use of tempering steel with specific mechanical properties and heat treatment protocols
- Suggests design features such as data chip holes and protection zones for static (non-rotating) and rotating applications

Applications

The ISO 26622-3:2026 standard brings practical benefits to manufacturers and machine tool builders, supporting:

Flexible Tooling Systems: Standardized shank dimensions streamline the integration of modular tooling; ideal for quick-change setups in automated and manual processes.
Interchangeable Tooling: Ensures compatibility across machine tools and peripheral equipment, minimizing downtime during tool exchange.
Precision Machining: Provides accurate and repeatable tool positioning for high-precision manufacturing operations, improving productivity and product quality.
Coolant Management: Supports efficient internal coolant delivery systems, critical for extending tool life and supporting high-speed machining.
Improved Maintenance: Standardized interfaces simplify maintenance, reduce spare part inventory, and facilitate faster service procedures.

Typical industries benefiting from this standard include automotive, aerospace, precision engineering, and general machining sectors where modular and adaptive tooling systems are essential.
