Overview
ISO 26622-4:2026 defines the critical dimensions for receivers used in modular taper interfaces with a ball track system utilizing four locking elements. This international standard ensures the compatibility and precision of machine tool interfaces, contributing to efficient and reliable tool exchange – both automatic and manual – across a range of machine tools such as lathes, drilling machines, milling machines, and turn/milling centers. Torque transmission within this system is achieved by friction and locking elements, supporting industrial demands for repeatable performance and process reliability.
Key Topics
- Modular Taper Interface: Specifies the interface dimensions for receivers designed for modular systems with ball track configurations and four locking points, allowing for standardized tool attachment and detachment.
- Dimensional Requirements: Details permitted tolerances for both linear and angular dimensions, supporting interchangeability and maintaining the integrity of tool connections between multiple brands and types of equipment.
- Receiver Sizes: Provides a range of standardized receiver sizes (e.g., TS4X63, TS4X100, TS4X125) to cover most industrial needs, facilitating integration into various machine tools.
- Clamping Force Guidance: Recommends appropriate clamping forces to guarantee stability and rigidity during machining processes, considering both light and heavy operational loads.
- Material and Heat Treatment: Outlines that receivers should be produced from high-strength steel with specified core strength and surface hardness, ensuring durability and longevity under industrial use.
Applications
- Machine Tool Industry: Widely applicable for any machine tool utilizing automatic or manual tool changes, including CNC machining centers, turning machines, and combination machines.
- Production Optimization: Enhances production line efficiency by enabling quick, repeatable, and secure tool changes without compromising on precision or machine uptime.
- Interoperability: Facilitates seamless integration of modular tools from different manufacturers, thanks to global standardization.
- Maintenance and Retrofits: Ideal for maintaining or upgrading existing machine tools to improve interface reliability or to enable the use of modular tooling systems with four-locking-element ball track receivers.
- Quality Assurance: Supports rigorous product quality and process consistency, as the standard defines strict tolerances for manufacturing and assembly.
Related Standards
- ISO 26622-3: Defines dimensions of shanks for modular taper interfaces with four locking elements, complementing ISO 26622-4’s specifications for the receiver components.
- ISO 8015: Specifies general rules and concepts for geometrical product specifications (GPS), providing foundational tolerancing principles referenced in ISO 26622-4.
- ISO 22081: Sets out general and geometrical size tolerances, ensuring dimensional consistency across components.
- ISO 1101: Relates to tolerances of form, orientation, location, and run-out; significant for ensuring the functional geometry of tool interfaces.
- ISO 3040: Covers dimensioning and tolerancing of cones, closely linked to the tapered profiles referenced in this standard.
By adhering to ISO 26622-4:2026, manufacturers and users of modular machine tool systems benefit from globally recognized interface dimensions, increased operational reliability, and improved compatibility within their production environments. This standard is crucial for anyone seeking to optimize tool exchange operations, facilitate cross-brand interoperability, and ensure consistent quality in machining processes.
