Overview
ISO 7755-6:2013 is an international standard developed by the International Organization for Standardization (ISO) that specifies the main dimensions for hardmetal burrs of arch shape with a round (ball) nose, designated as style F. This standard focuses exclusively on the cutting part dimensions of these precision rotary cutting tools widely used in metalworking and related industries.
This second edition of ISO 7755-6 updates and replaces the initial 1984 version, ensuring the industry benefits from standardized dimensions tailored for optimal interchangeability, precision, and performance in tooling applications involving hardmetal burrs.
Key Topics
-
Scope & Application
ISO 7755-6:2013 defines the critical dimensional parameters of arch-shaped, round-nose hardmetal burrs - tools essential for fine cutting, shaping, and surface finishing in advanced manufacturing contexts.
-
Cutting Part Dimensions
The standard provides clear specifications for:
- Cutting diameter (d)
- Profile radius (R)
- Cutting edge length (l)
These dimensions are essential for manufacturers and users to ensure compatibility and effectiveness of burr tools in precise machining operations.
-
Tolerance and Compatibility
Detailed tolerances relating to the cutting diameter, helix angle, direction of cut, and shank dimensions are managed under ISO 7755-1, which specifies general requirements for hardmetal burrs. This separation of requirements helps maintain clarity in design and quality control.
-
Designations and Symbols
Symbols such as ‘F’ for arch round (ball) nose burrs allow for standardized designation and easy identification in procurement and manufacturing workflows.
-
Relationship to ISO 13399
Annex A explains how designations in ISO 7755-6 relate to the ISO 13399 series, which governs cutting tool data representation and exchange, facilitating digital tool management and integration in CAD/CAM systems.
Applications
Hardmetal burrs conforming to ISO 7755-6:2013 are widely used in various sectors including:
-
Precision Metalworking
Ideal for deburring, shaping, and finishing metal surfaces with intricate contours where precision cutting edges are essential.
-
Mold and Die Making
Arch round (ball) nose burrs provide smooth finishes on complex mold cavities and die surfaces, improving final product quality.
-
Aerospace and Automotive Manufacturing
Used for tooling tasks requiring high durability and accurate milling in hard materials.
-
Tool Maintenance and Repair
Essential in finishing operations of cutting tools themselves or intricate mechanical parts needing precise material removal.
Utilizing burrs standardized under ISO 7755-6 guarantees consistency in tool performance, reduces manufacturing variances, and supports interoperability between different suppliers and machinery.
