ISO 19719:2010

Overview

ISO 19719:2010 - Machine tools - Work holding chucks - Vocabulary defines and standardizes the terminology used in clamping technology for work holding chucks. Its purpose is to systematize terms and facilitate clear communication among manufacturers, users, inspectors and trainers of machine tools. The standard applies to general commercial machine‑tool accessories (not to special or bespoke accessories) and provides English and French official terms; German equivalents are included for information.

Key topics and technical scope

ISO 19719:2010 organizes vocabulary and illustrations into practical subject areas:

• Types of clamping device - general designations for chucks and related movable-jaw devices (see manually operated chuck example in the standard).
• Components of chucks - names for body, jaws, slide blocks, driving ring, chuck cover and other parts for consistent identification.
• Hydraulic and pneumatic components - standard terms for actuators, seals and pressure-related elements used in power‑operated chucks.
• Clamping fixtures and accessories - vocabulary for fixtures, adapters and auxiliary items used with chucks.
• General terms for gripping technology - overarching terms used across gripping and workholding technologies.

Important editorial notes in the standard:

• Figures are illustrative only and are not intended to influence manufacturer design.
• Only the English and French terms are the official ISO designations; German terms are informational.
• Reproduction of the terms and definitions is permitted for educational or implementation publications under specified conditions.

Practical applications and who uses it

ISO 19719:2010 is primarily useful for:

• Machine tool and chuck manufacturers - to ensure consistent naming in documentation, manuals and part lists.
• Design and engineering teams - to remove ambiguity when specifying components or communicating across disciplines.
• Quality, inspection and maintenance personnel - to standardize defect reports, spare parts lists and service instructions.
• Technical writers, trainers and educators - for producing user manuals, training materials and teaching aids with approved terminology.
• Procurement and compliance specialists - to reference consistent vocabulary in contracts and conformity assessments.

Using a standardized vocabulary improves interoperability, reduces miscommunication in assembly and service, and supports global supply‑chain clarity for work holding chucks and clamping technology.

Related standards

ISO 19719:2010 cross‑references several normative documents that define dimensions and tests for spindle/chuck interfaces and self‑centring chucks:

• ISO 702 (Parts 1–4) - connecting dimensions of spindle noses and work holding chucks (conical, Camlock, bayonet, cylindrical).
• ISO 3442 (Parts 1–3) - dimensions and geometric tests for self‑centring chucks with two‑piece jaws (manual and power‑operated variants).
