ISO 3070-4:1998
Test conditions for boring and milling machines with horizontal spindle -- Testing of the accuracy -- Part 4: Planer type machines with movable column
This part of ISO 3070 specifies, with reference to ISO 230-1 and ISO 230-2, geometric tests, machining tests and tests for checking accuracy and repeatability of positioning by numerical control, on general purpose, normal accuracy, planer type horizontal spindle boring and milling machines with movable column. These types of machine tool are defined in subclauses 3.2 and 3.3 of ISO 3070-0:1982. This part of ISO 3070 also specifies the applicable tolerances corresponding to the above mentioned tests.
These machines can be provided with spindle heads of different types corresponding in most cases to figures:
- 4 (spindle head with sliding boring spindle and milling spindle)
- 5 (spindle head with sliding boring spindle and with facing head)
- 6 (spindle head with ram or milling ram)
In addition, it should be noted that this part of ISO 3070 concerns machines which have movement of the table along the X-axis, a vertical movement of the spindle head along the Y-axis, a movement of the column along the W-axis and may include a rotary or indexing table.
This part of ISO 3070 deals only with the verification of the accuracy of the machine. It does not apply to the testing of the machine operation (vibration, abnormal noise, stick-slip motion of components, etc.) nor to machine characteristics (such as speeds, feeds, etc.), as such checks are generally carried out before testing the accuracy.
