ISO 603-5:1999

Overview

ISO 603-5:1999 - "Bonded abrasive products - Dimensions - Part 5: Grinding wheels for surface grinding/face grinding" is an international standard that specifies the nominal dimensions (in millimetres) and designation rules for a range of grinding wheels used in surface (face) grinding. Published as the first edition in 1999, it is part of the ISO 603 series covering bonded abrasive product dimensions for many grinding applications.

This part applies to wheels intended for surface grinding where the workpiece is secured to a reciprocating table and both the workpiece and wheel are mechanically guided.

Key topics and requirements

• Types covered: Type 2 (cemented/clamped cylinder wheel), Type 6 (straight cup), Type 31 (segments), Type 35 (cemented/clamped disc), Type 36 (disc with inserted nuts), Type 37 (cylinder with inserted nuts).
• Dimensions: Nominal diameters, widths, heights and insert/pitch-circle layouts are provided in figures and tables for each wheel type. The standard gives standard sizes and insert-location patterns for larger disc wheels.
• Designation: A structured method for complete product designation (type, dimensions, abrasive nature, grain size, grade, structure, bond, and maximum operating speed). Example (from the standard):
  • Cylinder wheel ISO 603-5 - 2 - 300 100 -32 - A 46 H8B - 32 m/s
• Tolerances & run‑out: Limit deviations and run-out tolerances are referenced to ISO 13942.
• Balancing: Balancing requirements are referenced to ISO 6103 (static balancing testing).
• Marking & general requirements: Marking and general product requirements follow ISO 525.
• Illustrations and tables: Detailed figures and tables for dimensions, insert layouts and number/spacing of insert holes for various diameters.

Practical applications and users

ISO 603-5 is used by:

• Grinding wheel manufacturers for product design, consistent sizing, and label/marking practice.
• Machine builders and tool designers to ensure wheel-to-machine compatibility and correct insert patterns.
• Procurement and quality assurance teams to specify accepted nominal dimensions, tolerances and balancing classes for purchased wheels.
• Workshop and toolroom engineers to select wheels that meet interchangeability and safety requirements for surface/face grinding processes.
• Safety and compliance officers to verify maximum operating speeds and marking according to international norms.

Benefits include improved interchangeability, reduced specification ambiguity, safer operation, and easier international trade in bonded abrasive products.
