11、 12-1999 Foreword This British Standard has been prepared under the authority of the Mechanical Engineering Industry Standards Committee. It is based on proposals submitted by the Machine Tool Trades Association. It should be noted that broaching machines are dealt with in the BS 4656 “The accuracy
12、of machine tools and methods of test” series of standards. A British Standard does not purport to include all the necessary provisions of a contract. Users of British Standards are responsible for their correct application. Compliance with a British Standard does not of itself confer immunity from l
13、egal obligations. Summary of pages This document comprises a front cover, an inside front cover, pages i and ii, pages 1 to 4, an inside back cover and a back cover. This standard has been updated (see copyright date) and may have had amendments incorporated. This will be indicated in the amendment
14、table on the inside front cover. BS 5326:1976 BSI 12-19991 1 Scope This standard specifies a range of nominal shank dimensions for both the pull and tail ends of internal broaches for use on broaching machines, vertical type. The standard specifies certain dimensions for locating the pull chuck in t
15、he pull block of broaching machines, vertical internal type. The constant dimension between the top of the pull block and the platen surface is also given. The standard is particularly applicable to automatic handling of broaching tools. 2 Reference The title of the British Standard referred to in t
16、his standard is given on inside back cover. 3 Pull and tail ends of internal broaches 3.1 Dimensions. The shanks of both the pull and tail ends of broaches shall be of the form indicated in Figure 1 and conform to the dimensions given in Table 1. The overall length of the broach shall depend on the
17、particular application. The flat machined to dimension “G” is only used when the radial position of broach to workpiece is important. 3.2 Material and surface texture. The material of the broach and the surface texture of the shanks are left to the discretion of the manufacturer, but shall be consis
18、tent with the safe and efficient use of the broach. 3.3 Designation. Broach shanks complying with the requirements of this standard shall be designated by the number of the standard and the nominal shank diameter, e.g. BS 5326-20. 4 Pull chuck locations 4.1 Dimensions. The dimensions for the locatio
