Overview
ISO 10889-8:1997 specifies requirements for accessories used with tool holders featuring a cylindrical shank, focusing on Type Z accessories. Published by the International Organization for Standardization (ISO), this standard is part of the ISO 10889 series developed by ISO Technical Committee 29 (Small tools), and it is essential for the design, selection, and delivery of machine tool accessories. ISO 10889-8:1997 establishes specifications for clamping rings, sealing plugs, and ball-type nozzles, ensuring compatibility and interchangeability with tool holders on turning machines and similar equipment.
Key Topics
- Types of Accessories: This standard addresses Type Z accessories, including:
- Clamping rings (Type Z1)
- Sealing plugs (Type Z2)
- Ball-type nozzles (Type Z3)
- Dimensions and Tolerances: Specifies dimensional requirements, with general tolerances following ISO 2768-1 for linear and angular dimensions.
- Materials: Defines suitable materials for each accessory type, such as steel for clamping rings and sealing plugs, and either copper-zinc alloy or stainless steel for ball-type nozzles, with some discretion allowed to manufacturers.
- Designation System: Provides a standardized naming convention for each accessory that includes the type, nominal diameter, and reference to ISO 10889-8.
- Technical Delivery Conditions: Details requirements for the delivery of accessories, including design considerations and provided components (e.g., clamping screw for clamping rings).
Applications
ISO 10889-8:1997 is vital for manufacturers, suppliers, and end-users in the machine tool industry who need to ensure:
- Compatibility: Accessories conforming to this standard are designed to fit tool holders with cylindrical shanks specified in ISO 10889-2 through ISO 10889-7, facilitating standardized assembly and maintenance.
- Interchangeability: Use of standardized accessories streamlines spare parts management, replacement procedures, and international procurement.
- Operational Efficiency: Proper selection and use of clamping rings, sealing plugs, and ball-type nozzles support effective coolant delivery and sealing in machine tool operations, especially in turning machines.
- Quality Assurance: Adherence to specified dimensions, materials, and tolerances ensures consistent performance and reliability for critical tooling accessories.
Typical industrial applications include CNC turning centers, manual lathes, and other machines using non-rotating tools with cylindrical shank holders.
Related Standards
For comprehensive compliance and full system integration, ISO 10889-8:1997 should be used alongside other parts of the ISO 10889 series and relevant tolerancing and specification standards:
By referencing and complying with these standards, organizations can ensure high-quality, standardized tool holder systems and accessories across their supply chain and manufacturing operations. This enhances process efficiency, reduces variability, and simplifies global sourcing of machine tool components.
