ISO 603-6:1999

Overview

ISO 603-6:1999 - "Bonded abrasive products - Dimensions - Part 6: Grinding wheels for tool and tool room grinding" defines the nominal dimensions (in millimetres) and shape types of bonded grinding wheels used for grinding and regrinding cutting faces and edges of tools. It is one part of the ISO 603 series covering bonded abrasive product dimensions and applies to mechanically guided grinding operations in toolrooms and production environments.

Key topics and technical requirements

• Wheel types and shapes: The standard specifies dimensional data and drawings for commonly used shapes including:
  • Type 1 - Straight grinding wheel (general application and saw sharpening)
  • Type 3 - Wheel tapered on one side
  • Type 5 - Wheel recessed on one side
  • Type 6 - Straight cup wheel
  • Type 7 - Wheel recessed on both sides
  • Type 11 - Taper cup wheel
  • Type 12 - Dish wheel
• Nominal dimensions: Detailed nominal sizes are given in figures and tables for each wheel type (diameter, thickness, bore, recesses, cup depths, etc.).
• Designation format: A complete product designation includes wheel type, dimensions, abrasive nature, grain size, grade, structure, bond type and maximum operating speed (the standard includes an example format).
• Tolerances and run-out: Limit deviations and run-out tolerances are referenced to ISO 13942.
• Balancing: Static balancing and testing are referenced to ISO 6103.
• Marking and general requirements: Marking and general product requirements follow ISO 525. Detailed manufacturer specifications (e.g., abrasive composition) are left to the manufacturer but must conform to referenced standards.

Practical applications

• Regrinding and finishing of cutting tools (drills, taps, lathe tools, saw blades)
• Toolroom and maintenance work where precision tool edges are restored
• Production environments where tool geometry and surface finish affect process quality
• Machine shops and sharpening services requiring standardized wheel interchangeability and safety information

Who uses this standard

• Abrasive product manufacturers (for wheel design and labeling)
• Toolroom managers and technicians (for selecting correct wheel types)
• Purchasing and quality engineers (to specify and verify wheel dimensions and markings)
• Machine builders and safety officers (to ensure compatibility and safe operating speeds)
