13、. BS 1916-1, Limits and tolerances. In view of the measure of agreement that has been achieved internationally on the dimensional standardization of lathe spindle noses and faceplates, it has been considered opportune to prepare a British Standard implementing the recommendations of Technical Commit

14、tee39 Machine Tools of the International Organization for Standardization (ISO). This British Standard has accordingly been based on ISO Recommendation R702 which provides dimensions and tolerances for two types of lathe spindle noses and faceplates (Types “A” and “Camlock”). It is intended that a f

15、urther part of this standard shall cover the dimensions of bayonet type spindle noses as soon as international agreement on this type has been achieved. Interchangeability. Although internal parts such as cams, screws and studs made to this specification will not interchange with similar parts made

16、to an inch specification, there is strict operational interchangeability for one same type (AorCamlock) between metric spindle noses and inch faceplates and vice versa. A British Standard does not purport to include all the necessary provisions of a contract. Users of British Standards are responsib

17、le for their correct application. Compliance with a British Standard does not of itself confer immunity from legal obligations. Summary of pages This document comprises a front cover, an inside front cover, pagesi andii, pages1 to13 and a back cover. This standard has been updated (see copyright dat

18、e) and may have had amendments incorporated. This will be indicated in the amendment table on the inside front cover.BS4442-1:1969 BSI 01-2000 1 1 Scope 1.1 This British Standard specifies dimensions for the following types of lathe spindle noses, their faceplates and component parts: Accessories fo
