BS 4656-18:1981

This standard BS 4656-18:1981 Accuracy of machine tools and methods of test is classified in these ICS categories:

• 25.080.30 Broaching machines

This Part of this British Standard specifies, with reference to BS 3800, geometrical tests for broaching machines, horizontal internal type and gives corresponding permissible deviations which apply.

This standard is applicable to machines of general purpose use and normal accuracy.

It deals only with the verification of accuracy of the machine. It does not apply to the testing of the running of the machine (vibrations, abnormal noises, stick-slip motion of components etc.) nor to its characteristics (speeds, feeds, etc.) which should generally be checked before testing accuracy.

Geometrical tests and corresponding permissible deviations.
