The technical differences between this document and ISO 603-14:2022 and their reasons are as follows.

--- ISO 525 (see Chapter 4) has been replaced by the normative reference GB/T 2484 to adapt to my country's technical conditions;

--- Added the size series of type 6 grinding wheels with embedded threads (see Table 1) to conform to my country's actual situation;

--- Added the specifications for the end face width of the type 11 grinding wheel ring with embedded threads (see Table 3) to conform to my country's actual situation;

--- Added the size series of cymbal grinding wheels (type 27) and deleted the indication for cutting (see 4.3) to conform to the actual situation in my country;

--- Added the size series of conical cymbal grinding wheels (type 28) (see Table 6) to conform to my country's actual situation.

The following editorial changes have been made to this document.

--- Deleted the imperial size representation of the outside diameter in the international standard;

--- Deleted the notes in 4.3 to 4.5 of the international standard;

Introduction

In order to facilitate the production, trade, application and technical exchange of bonded abrasives and make rational use of resources, it is necessary to establish a standardized bonded abrasive tool scale.

Bonded abrasives have various shapes and uses. Products with the same shape may have different uses, and products with the same use may also have different with the development of bonded abrasives industry, the advancement of technology and the change of market demand, its shapes and uses are constantly enriched, and its size is constantly increasing.

The size system of bonded abrasive tools is becoming increasingly large, and it is becoming increasingly difficult to establish a size system of bonded abrasive tools through a single standard, which is no longer realistic.

Since.1999, ISO/TC29/SC5 has established a new bonded abrasive tool size system through scientific and reasonable classification and released ISO 603 series standards. GB/T 4127 "Dimensions of bonded abrasives" has adopted ISO 603 series standards since its second revision.

It consists of 18 parts.

--- Part 1: External cylindrical grinding wheels (workpiece clamped between centers). The purpose is to specify external cylindrical grinding wheels (workpiece clamped between centers) Common nominal sizes.

--- Part 2: Centerless external cylindrical grinding wheels. The purpose is to specify the commonly used nominal dimensions of centerless external cylindrical grinding wheels.

--- Part 3: Internal grinding wheels. The purpose is to specify the commonly used nominal sizes of internal grinding wheels.

--- Part 4: Peripheral grinding wheels for surface grinding. The purpose is to specify the commonly used nominal sizes of peripheral grinding wheels for surface grinding.

--- Part 5: End grinding wheels for surface grinding. The purpose is to specify the commonly used nominal dimensions of end grinding wheels for surface grinding.

--- Part 6: Grinding wheels for tool grinding and tool room use. The purpose is to specify the commonly used nominal sizes of grinding wheels for tool grinding and tool room use.

--- Part 7: Manually operated grinding wheels. The purpose is to specify the commonly used nominal sizes of manually operated grinding wheels.

--- Part 8: Grinding wheels for deburring, roughing and rough grinding. The purpose is to specify the common nominal size.

--- Part 9: Heavy-duty grinding wheels. The purpose is to specify the commonly used nominal sizes of heavy-duty grinding wheels.

--- Part 10: Honing and superfinishing grinding stones. The purpose is to specify the commonly used nominal sizes of honing and superfinishing grinding stones.

--- Part 11: Hand-held polishing stones. The purpose is to specify the commonly used nominal sizes of hand-held polishing stones.

--- Part 12: Deburring and roughening wheels for straight grinding machines. The purpose is to specify deburring and roughening wheels for straight grinding machines Common nominal sizes.

--- Part 13: Deburring and roughening wheels for vertical grinding machines. The purpose is to specify deburring and roughening wheels for vertical grinding machines Common nominal sizes.

--- Part 14: Deburring, roughing and grinding wheels for angle grinders. The purpose is to specify the deburring, roughing and grinding wheels for angle grinders.

Common nominal sizes for rough and coarse grinding wheels.

--- Part 15: Cutting wheels for fixed or mobile cutting machines. The purpose is to specify the cutting wheels for fixed or mobile cutting machines.

Common nominal sizes of grinding wheels.

--- Part 16: Cutting wheels for hand-held power tools. The purpose is to specify the commonly used specifications for cutting wheels for hand-held power tools.

Weigh the size.

--- Part 17: Mounted grinding points. The purpose is to specify the commonly used nominal sizes of mounted grinding points.

--- Part 18: Grinding wheels for flat glass edging. The purpose is to specify the commonly used nominal sizes of grinding wheels for flat glass edging.

Dimensions of bonded abrasive tools - Part 14: Angle grinders Deburring, roughing and rough grinding wheels

1 Scope

This document specifies the commonly used nominal sizes and designations of the following bonded abrasive tools, in millimeters.

---Type 6.cup grinding wheel;

---Type 11.bowl-shaped grinding wheel;

---Type 27.cymbal-shaped grinding wheel;

---Type 28.conical cymbal grinding wheel;

---Type 29.convex cymbal-shaped grinding wheel.

The bonded abrasives specified in this document are suitable for deburring, rough grinding and rough grinding of any surface of a workpiece using a hand-held angle grinder.

In this application, the workpiece is stationary and the grinder is controlled by the operator.
