ISO/TC 29/SC 5/WG 5 - Bonded abrasives

This document specifies the essential limit deviations and run-out tolerances for bonded abrasive products.

ISO 6103:2014 specifies the maximum permissible values of unbalances for bonded abrasive wheels with an outside diameter D ≥ 125 mm and maximum operating speed vs ≥ 16 m/s, in the as-delivered condition. It also specifies the method for measuring the unbalance and the practical method for testing whether a grinding wheel is acceptable or not. It is applicable to bonded abrasive wheels in the as-delivered condition. It is not applicable to diamond, cubic boron nitride or natural stone grinding wheels, or to centreless control wheels, lapping and disc wheels, ball wheels or glass grinding wheels.

ISO 603-17:2014 specifies the current shapes, nominal dimensions and limit deviations, in millimetres, of Type 52: Spindle mounted wheels. These bonded abrasive products are intended to be used for hand-held grinding and manually guided or on hand-held power tools guided by hand.

ISO 525:2013 is applicable to bonded abrasive products (e.g. grinding wheels, segments, sticks and stones) in general, excluding superabrasive products and coated abrasive products. ISO 525:2013 specifies: the ISO type number and shape; dimensional symbols; standard profiles; requirements for dimensions, limit deviations and tolerances as well as permissible unbalance; the specification mark; the marking requirements.

ISO 603-18:2013 specifies the shapes, dimensions and limit deviations, in millimetres, of grinding wheels for flat glass edge grinding machines. This type of bonded abrasive wheel is intended to be used on stationary machines where the position of the grinding wheel is fixed and the workpiece is guided by hand or guided mechanically, or on a stationary machine where the grinding wheel is guided mechanically and the workpiece is fixed.

ISO 6103:2005 specifies the maximum permissible values of unbalances for various grinding wheels of ISO 603-1 to ISO 603-9 and ISO 603-12 to ISO 603-16 in the as-delivered condition, with an outside diameter greater than 115 mm and maximum operating speed greater than or equal to 16 m/s. It also specifies the method for measuring the unbalance and the practical method for testing whether a grinding wheel is acceptable or not. ISO 6103:2005 is applicable to bonded abrasive grinding wheels in the as-delivered condition. It is not applicable to diamond, cubic boron nitride or natural stone grinding wheels, or centreless control wheels, lapping and disc wheels, ball wheels or glass grinding wheels.
