ISO DIS 17543-1

Description / Abstract: This document specifies, with reference to the parts of ISO 230 quoted in clause 2 hereunder, some families of tests for accessory spindle heads used on machining centres or numerically controlled milling machines, etc. where applicable, with horizontal spindle (i.e. horizontal Z‐axis). The tests considered in this document are also applicable to manual indexing heads. Grinding heads and facing heads are not included in the scope of this document.

This document deals only with the verification of geometric and positioning accuracy of the accessory spindle heads and does not apply to the testing of the machine’s head(s) operation (e.g. vibration, abnormal sound noise level, stick slip motion of components), nor to the machine’s spindle head(s) characteristics (e.g. speeds, feeds and accelerations) which should generally be checked separately, nor to the verification of the machining capability under power. Tests concerning the accuracy of finished test pieces are dealt with in other ISO standards.
