NBN ISO 6481:2021

This document specifies, with reference to ISO 230-1, the geometric tests on surface type broaching
machines with vertical Z-axis providing the main cutting motion.
It also specifies the applicable tolerances corresponding to the tests mentioned above for normal-
accuracy vertical surface type broaching machines.
This document explains different concepts or configurations and common features of vertical surface
type broaching machines. It also provides related terminology and designation of axes.
This document deals only with the verification of the accuracy of the broaching machine.
It does not apply to the operational testing of the broaching machine (e.g. vibration, abnormal noise,
stick-slip motion of components), nor to broaching machine characteristics (e.g. speeds, feeds) as such
checks are generally carried out before testing the accuracy.
