18、 Copy: London South Bank University, London South Bank University, Fri Feb 15 06:44:04 GMT+00:00 2008, Uncontrolled Copy, (c) BSI v Introduction It is generally accepted that horizontal spindle boring and milling machines fall into three categories characterized by their particular configuration: a)
19、 machines with fixed column and movable table; b) machines with movable column and fixed table; c) machines with movable column and movable table. In the past, all these types of machines and associated terminology were described in ISO 3070-0:1982. The relevant accuracy tests were described in ISO
20、3070-2:1997, ISO 3070-3:1997, and ISO 3070-4:1998 respectively. However, ISO/TC 39/SC 2 decided to integrate the descriptions and the terminology of these machines into appropriate parts of ISO 3070 describing the accuracy tests and to renumber the parts of this series accordingly.

22、Test conditions for testing the accuracy of boring and milling machines with horizontal spindle Part 2: Machines with movable column and fixed table 1 Scope This part of ISO 3070 specifies, with reference to ISO 230-1, ISO 230-2 and ISO 230-7 geometric tests, machining tests, spindle tests and tests
23、 for checking the accuracy and repeatability of positioning by numerical control of general purpose, normal accuracy, horizontal spindle boring and milling machines having a movable column and fixed table. This part of ISO 3070 also specifies the applicable tolerances corresponding to these tests. T
