Foreword
This Standard is drafted in accordance with the rules given in GB/T 1.1-2009.
This Standard replaces GB/T 23541-2009 “Bonded abrasive products -
Grinding wheel for steel balls”. As compared with GB/T 23541-2009, the main
technical changes are as follows.
- MODIFY the scope of application (SEE Chapter 1; Chapter 1 of the 2009
version);
- ADD normative references GB/T 2484 “Bonded abrasive products -
General requirements”, GB/T 2485 “Bonded abrasive products - Technical
specifications”, and GB 2494 “Bonded abrasive products - Safety
requirements” (SEE Chapter 2);
- ADD the basic dimensions (SEE Table 2 in 3.2), limit deviation (SEE Table
4 in 4.2), geometrical tolerancing (SEE 4.3), hardness value and the test
method (SEE 5.2 and Appendix A) of the resinoid bonded grinding wheel
for steel balls;
- MODIFY the technical requirements for appearance of vitrified grinding
wheel for steel balls (SEE 4.4; 5.4 of the 2009 version);
- MODIFY the marking of grinding wheel (SEE 4.6; Chapter 8 of the 2009
version);
- MODIFY the hardness test method of vitrified grinding wheel for steel balls
(SEE 5.2; 6.2 of the 2009 version);
- ADD requirements for transport and storage (SEE Chapter 7).
This Standard was proposed by China Machinery Industry Federation.
This Standard shall be under the jurisdiction of National Technical Committee
139 on Abrasives and Sharper of Standardization Administration of China
(SAC/TC 139).

4.4 Appearance
The grinding wheel shall be free of any inclusions, delamination, or cracks.
4.5 Hardness
Vitrified bonded grinding wheel for steel balls shall be inspected for hardness
compliance and uniformity. The abrasive blasting hardness pit depth value shall
not be more than 0.6 mm. The hardness uniformity shall not be more than 0.15
mm. Resinoid bonded grinding wheel for steel balls shall be inspected for
hardness uniformity. The uniformity shall not be more than 3 HRC.
4.6 Marking
The marking of grinding wheel shall comply with the provisions of GB/T 2485.
The working surface shall be marked.
5 Test methods
5.1 The limit deviation of basic dimensions, geometrical tolerancing,
appearance, and marking of grinding wheel shall be inspected in accordance
with the provisions of JB/T 7992.
5.2 The hardness of vitrified bonded grinding wheel for steel balls shall be
tested according to the provisions of GB/T 2490. The test is carried out with a
28 cm3 sand chamber; the abrasive blasting hardness test is performed 3 times
per point; and the 3rd test value is taken as the final hardness value. The
hardness uniformity of grinding wheel is the absolute value of the difference
between the ......
