This third revision is identical with ISO11

14、80:1983 including Addendum 1 published in 1985, “Shanks for pneumatic tools and fitting dimensions of chuck bushings” which was prepared by Technical Committee ISO/TC 29, Small tools, of the International Organization for Standardization (ISO) and in the development of which the United Kingdom playe

15、d an active part. As compared with the 1973 edition, in which due account was taken of the related ISO recommendations, R 1180 and R 1571 “Shanks for pneumatic tools and fitting dimensions of chuck bushings”, Parts I and II, it should be noted that ISO 1180:1983 replaces both of these recommendation

16、s of which it constitutes a technical revision. Terminology and conventions. The text of the International Standard has been approved as suitable for publication as a British Standard without deviation. Some terminology and certain conventions are not identical with those used in British Standards;

17、attention is drawn especially to the following. The comma has been used as a decimal marker for metric dimensions. In British Standards it is current practice to use a full point on the baseline as the decimal marker. Wherever the words “International Standard” appear, referring to this standard, th

18、ey should be read as “British Standard”. Cross references The Technical Committee has reviewed the provisions of ISO296:1974 and ISO723:1974, to which reference is made in the text, and has decided that they are acceptable for use in conjunction with this standard. A related British Standard to ISO2

19、96:1974 is BS 1660:1972 “Machine tapers, reduction sleeves and extension sockets.” 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 itsel

This standard has been updated (see copyright date) and may have had amendments incorporated. This will be indi

21、cated in the amendment table on the inside front cover.iv blankBS673:1984 BSI 12-1999 1 1 Scope and field of application This International Standard relates to shanks for pneumatic tools and corresponding chuck bushings and deals with the following types: coal pick shanks; chisel shanks; rivet snap

22、shanks, parallel; rivet snap shanks, tapered; breaker and spade shanks; concrete breaker shanks; rock drill shanks. The types relate to the machine for which they are mainly designed, but this does not prevent the use of the shanks for other applications. Other types of tools will be dealt with in f

23、urther International Standards when the corresponding studies are completed. Pneumatic hammers and their chuck bushings are not covered by this International Standard but those features of chuck bushings (dimensions and tolerances) which ensure interchangeability are specified. For each tool mention

24、ed above, this International Standard provides tables giving dimensions in millimetres. Dimensions in inches are given in the Annex which be valid for five years from the date when this International Standard is approved. 2 Reference ISO 723, Rock-drilling Forged collared shanks and chuck bushings f

25、or hollow hexagonal drill steels. ISO 296, Machine tools Self-holding tapers for tool shanks. 3 Interchangeability The numerical values specified in this International Standard ensure interchangeability even if the shank and the corresponding chuck bushing are not manufactured in the same system of

26、units. 4 Designation of shanks The designation of shanks should be composed of the name of the type of shank; the shank size (first column in the tables); the length of the shank.

31、nal portion s are included in the tolerance given in Table 2; the “Go” gauge for dimensions d and s should therefore be a composite gauge. This remark also refers to the measurements of the corresponding chuck bushings. NOTE 3As an alternative to tool with hexagon shank (see Figure 2) the hexagon po

32、rtion may be replaced by a cylindrical portion with the same length l 1and a diameter s equal to the width across flats of the hexagon (see Figure 3). NOTE 4On shanks with a hexagon portion, the cutting edge of the chisel should be parallel to one of the sides of the hexagon. Example of designation
