标准简介
Describes both special tests and practical tests for hydraulic and electric servo-controlled copying attachments (not for mechanically controlled ones) of general-purpose normal precision (centre lathes, vertical boring machines, capstan lathes or others) and copying lathes. The tests are intended to supplement the tests for the various types of lathes. It also applies to lathes with single-axis copying systems and to lathes where two axes are used in conjunction to produce a profile of up to 180 degrees included angle.
