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.
