ISO 603-4:1999

Overview

ISO 603-4:1999 - "Bonded abrasive products - Dimensions - Part 4: Grinding wheels for surface grinding/peripheral grinding" defines the nominal dimensions (mm), types and designation rules for bonded grinding wheels used in surface and peripheral grinding. It applies to wheels intended for grinding plane surfaces where the workpiece is secured to a reciprocating table and both workpiece and grinding wheel are mechanically guided. The standard standardizes shapes (Types 1, 5, 7, 20, 21, 22–26, 38, 39), dimension tables and the format for product designation.

Key topics and technical requirements

• Scope and Types: Specifies a range of wheel shapes - e.g., Type 1 (straight), Type 5/7 (recessed), Types 20–26 (relieved/recessed combinations), Type 38/39 (hubbed/double-hubbed) - with nominal dimension tables in millimetres.
• Dimensions: Nominal diameters, thicknesses, bore/hub sizes and recess/relief parameters are tabulated for each wheel type (millimetre units).
• Designation format: Defines the complete product designation elements: product name, ISO reference, type (shape), dimensions, internal specifications (abrasive type, grain size, grade, structure, bond) and maximum operating speed. The standard includes an example designation format.
• Normative requirements:
  • Tolerances and run-out: Refer to ISO 13942 for limit deviations and run-out tolerances.
  • Balancing: Testing and balancing requirements reference ISO 6103.
  • Marking and general requirements: Per ISO 525.
• Specifications: Detailed internal specifications (grain size, bond, etc.) are left to manufacturer discretion but shall be declared per ISO 525 conventions.

Applications and who uses it

ISO 603-4 is primarily used by:

• Abrasive product manufacturers - for designing and producing grinding wheels to internationally accepted dimensional specifications.
• Machine builders and OEMs - to ensure wheel compatibility with surface grinding/peripheral grinding machines.
• Purchasing and procurement - to specify exact wheel type and dimensions in purchase orders.
• Quality assurance and inspection - to verify wheel dimensions, marking and balancing against standardized requirements.
• Toolroom and maintenance personnel - for correct wheel selection, identification and safe operation at specified maximum speeds.

Practical applications include surface finishing, plane-surface grinding of components secured on reciprocating tables, and peripheral grinding operations in metalworking and toolrooms.
