This document replaces GB/T 4127.9-2007 "Dimensions of Bonded Abrasives - Part 9: Heavy-Duty Grinding Wheels", and is consistent with GB/T 4127.9-Compared to 2007, aside from structural adjustments and editorial changes, the main technical changes are as follows.

a) The dimensions of the grinding wheel were changed (see Table 1, 2007 edition);

b) The requirement has been removed (see Chapter 5 of the 2007 edition).

This document is modified to adopt ISO 603-9:2024 "Bound abrasive dimensions - Part 9: Heavy-duty grinding wheels".

The technical differences between this document and ISO 603-9:2024, and the reasons therefor, are as follows.

---ISO 525 has been replaced with the normatively referenced GB/T 2484 (see Chapters 4 and 5) to adapt to my country's technical conditions;

---The commonly used size series of grinding wheels has been added (see Table 1) to conform to the actual situation in my country.

The following editorial changes have been made to this document.

---References in international standards have been removed.

Introduction

To facilitate the production, trade, application, and technical exchange of bonded abrasives, and to ensure the rational use of resources, it is necessary to establish standardized bonded abrasive dimensions.

Size system. Bonded abrasives come in a variety of shapes and have diverse uses; products of the same shape may have different applications, and products of the same purpose may also have different dimensions.

In various shapes. With the development of the bonded abrasives industry, technological advancements, and changes in market demand, their shapes and applications are constantly expanding, and their sizes are also increasing.

As the system grows larger, establishing a dimensional system for bonded abrasives through a single standard becomes increasingly difficult and impractical.

Since.1999, ISO/TC29/SC5 has established a new dimensional system for bonded abrasives through scientific and reasonable classification, and has published [the relevant documents/reports].

The ISO 603 series standards. GB/T 4127 "Dimensions of Bonded Abrasives" has adopted the ISO 603 series standards since its second revision, and is proposed to be revised by ten...

It consists of eight parts.

---Part 1: External Cylindrical Grinding Wheel (Workpiece Clamped Between Centers). The purpose is to specify the external cylindrical grinding wheel (workpiece clamped between centers).

Commonly used nominal dimensions.

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

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

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

---Part 5: Face Grinding Wheels for Surface Grinding. The purpose is to specify the commonly used nominal dimensions of face grinding wheels for surface grinding.

---Part 6: Grinding wheels for tool grinders and tool chambers. The purpose is to specify the commonly used nominal dimensions of grinding wheels for tool grinders and tool chambers.

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

---Part 8: Deburring, Roughing, and Coarse Grinding Wheels for Stationary Machines. The purpose is to specify the deburring, roughing, and coarse grinding wheels for stationary machines.

Commonly used nominal dimensions for coarse grinding wheels.

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