ISO 3070-2:2007 Machine tools - Test conditions for testing the accuracy of boring and milling machines with horizontal spindle - Part 2: Machines with movable column and fixed table
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 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.
This type of machine can be provided with spindle heads of different types, such as those with sliding boring
spindle and milling spindle, sliding boring spindle and facing head, or ram or milling ram.
This part of ISO 3070 concerns machines having movement of the column or column saddle on the bed
(X axis), vertical movement of the spindle head (Y axis), movement of the boring spindle or ram (Z axis) and,
possibly, a feed movement of radial facing slide in the facing head (U axis). Some machines also have an
intermediate saddle with slideways between column and bed to achieve additional movement of the column
parallel to the spindle axis (W axis).
NOTE In ISO 3070-1, spindle ram movement is designated as the W axis.
This part of ISO 3070 deals only with the verification of the accuracy of the machine. It does not apply to the
operational testing of the machine (e.g. vibration, abnormal noise, stick-slip motion of components) nor to
machine characteristics (e.g. speeds, feeds), as such checks are generally carried out before testing the
accuracy.
