This Standard establishes requirements and methods for specifying and testing the performance of CNC lathes and turning centers. In addition to clarifying the performance evaluation of lathes and turning centers, this Standard seeks to facilitate performance comparisons...
Purpose: This specification provides a standard for the manufacture, performance, inspection, and procurement of a series of numerically controlled precision, horizontal spindle turning machines.
Specifies sizes for interchangeability of lathe spindle noses and faceplates of the bayonet type.
Design considerations and dimensions, related to the horizontal level of the lathe axis, of the internal heights of lathe tool posts, suitable with a few exceptions which are noted, for the tool shanks specified in ISO/R 241 and BS 1296. Principally for t
