Overview
ISO 15637-1:2002 specifies requirements for holding fixtures with shank used in conjunction with cylindrical abrasive sleeves, primarily on hand-held grinding machines. This standard covers holding fixtures designed to accommodate abrasive sleeves with diameters up to 100 mm as defined by ISO 2421. These fixtures typically feature lamellar cores that expand under centrifugal forces during operation, securely clamping the abrasive sleeves for safe and efficient grinding.
This international standard, published by ISO’s Technical Committee ISO/TC 29, Subcommittee SC 5 on Grinding wheels and abrasives, provides uniform design, material, and performance requirements, ensuring compatibility and safety in manual grinding applications.
Key Topics
-
Scope and Application
ISO 15637-1 targets holding fixtures with shank diameters up to 100 mm used on portable, hand-held grinding machines. It excludes fixtures for stationary machinery, which are covered under Part 2 of the standard.
-
Design and Dimensions
The standard outlines essential dimensions and tolerances that must be met, while allowing manufacturers flexibility in the overall design and shape of the holding fixtures. Key parameters such as diameter (DT), thickness (T), and shank diameter (S) are standardized to maintain interchangeability.
-
Materials and Construction
The lamellar core of the holding fixture must be made of rubber, with the material type chosen by the manufacturer to withstand operational stresses. The shank is required to be steel with a minimum yield strength of 300 N/mm² to ensure mechanical integrity and safety during use.
-
Performance Under Centrifugal Forces
A crucial aspect of the standard is the behavior of the lamellae when rotating at high speed-the centrifugal force causes the lamellae to expand radially, thereby securely clamping the abrasive sleeve onto the fixture without additional mechanical fasteners.
-
Designation and Marking
The standard specifies a uniform method for designating holding fixtures by type, reference to ISO 15637-1, dimensions, and maximum speed rating. Marking practices are left to manufacturer discretion but must provide clear identification for proper application and safety compliance.
Applications
ISO 15637-1:2002 is particularly relevant to:
- Manufacturers producing holding fixtures for hand-held grinding tools needing standardized designs to ensure product safety and compatibility.
- Tool users and maintenance personnel who require reliable holding fixtures that securely retain abrasive sleeves during high-speed grinding operations.
- Quality assurance teams aiming to verify conformance of holding fixtures with international safety and performance criteria.
- Safety regulators enforcing equipment standards to prevent accidents and improve workplace safety in metalworking, fabrication, and construction industries.
By adhering to ISO 15637-1, companies can ensure their tools meet recognized international standards, improving customer confidence and helping minimize operational risks associated with abrasive sleeve handling.
