Foreword

This standard is drafted in accordance with the rules given in GB/T 1.1-2009. This standard replaces GB/T 1132-2004 "Reamer for Straight Shank and Morse Taper Shank". This standard is compared with GB/T 1132-2004 The technical changes are as follows. - the provisions of the scope of the recommended only and the provisions of the provisions of the metric size, straight handle and Mohs taper shank with other provisions of the reamer 3.1 In the provisions; - adjust the contents of the original standard range to the third chapter type and size; --- modified the normative reference file; --- all figures and the table sign reamer diameter d, total length L, blade length l, handle length l1, handle diameter d1 by the standard symbol D1, l1, l2, l3, d2 instead; --- the original Chapter 3 "handle" the contents of the adjustment to Chapter 3; - increase 3.1 general requirements; - Chapter 4 Title is changed from "Tolerance" to "Length Tolerance", part of which is adjusted to Chapter 3; - adjust the size of the original reamer in Chapter 5 and Chapter 6 to Chapter 3; --- adjust the original 7th chapter mark example to the fifth chapter mark example; - Table 2 and Table 4 add to the description of the cutting diameter measurement and the special tolerance reamer length and handle size and tolerances. This standard uses the re-drafting method to modify the ISO 521..2011 "straight handle and the Mo's taper shank reamer". The technical differences between this standard and ISO 521..2011 are as follows. - modified the scope of the international standard (see Chapter 1), part of the content included in 3.1, the reasons for the editor; - normative reference documents, ISO 237 replaced with GB/T 4267; ISO 296 replaced with GB/T 1443; increased GB/T 4246 (see Chapter 2); - In accordance with the actual situation in the country, in 3.1 to increase the processing of specific tolerance hole reamer diameter tolerance requirements; --- Find the reason for convenience, increase the length of Chapter 4 tolerance, the length of the table tolerance included in this chapter; --- According to the actual situation of the country, an example of the fifth chapter is added; --- According to the actual situation in the country, Appendix A has been added. Compared with ISO 521..2011, the editorial changes are as follows. --- modify the indication position of "1" in Figure 1; The instructions in Figure 1 and Figure 2 are adjusted to 3.2 and 3.3. This standard is proposed by the China Machinery Industry Federation. This standard is under the jurisdiction of the National Tool Standardization Technical Committee (SAC/TC91).
