Machine tools — Test conditions for external cylindrical centreless grinding machines — Testing of the accuracy
Preview
Summary
The document specifies, with reference to ISO 230-1 and ISO 230-2, geometric tests, machining tests
and tests for accuracy and repeatability of positioning axes on general purpose and normal accuracy
manually and numerically controlled (NC) external cylindrical centreless grinding machines. It also
specifies the applicable tolerances corresponding to the above-mentioned tests.
This document deals only with the verification of accuracy of the machine. It does not apply to the
testing of the machine operation (vibrations, abnormal noise, stick-slip motion of components, etc.) nor
to machine characteristics (such as speeds, feeds, etc.), which are generally checked before testing of
machine accuracy.
This document provides the terminology used for the principal components of the machine and the
designation of the axes with reference to ISO 841.
NOTE In addition to the terms used in the official ISO languages (English and French), this document
gives the equivalent terms in the German, Italian, Japanese, and Persian languages. These are published under
the responsibility of the national member bodies for Germany (DIN), Italy (UNI), Japan (JIS), and Iran (ISIRI).
However, only the terms given in the official languages can be considered as ISO terms.
