ASME B5.9:1967(R2014)

Die Annotation des Normtextes ASME B5.9:1967(R2014) :

This standard is being maintained under Stabilized Maintenance. Stabilized maintenance is an option for maintenance of a standard that requires status review every 10 years rather than revision or reaffirmation every 5 years. The Standards Committee shall consider all requests and recommendations for change to standards maintained under the stabilized maintenance option from any materially affected and interested party. The request shall be made in writing and should include the rationale for the particular request in order to facilitate review by the Committee.
This Standard pertains to spindle noses for use on engine lathes, tool room lathes, turret lathes and automatic lathes and may be used advantageously on other machines wherever chucks or fixtures must be mounted accurately and rigidly on revolving spindles. Complete dimensions for each size and type of nose, as well as for mating backs of chucks, face plates and fixtures, are given in the tables. Also given are dimensions of gages for checking the important dimensions on these spindle noses and the backs of chucks, face plates and fixtures, to insure interchangeability between parts made by different manufacturers.
