BS 4656-10:1975

This standard BS 4656-10:1975 Specification for the accuracy of machine tools and methods of test is classified in these ICS categories:

• 25.080.40 Drilling machines

This Part of this British Standard specifies, with reference to BS 3800, both geometrical and practical tests for drilling machines of the radial type and gives corresponding permissible deviations which apply. This standard is applicable to machines of general purpose use and normal accuracy.

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.) not to its characteristics (speeds, feeds etc.) which should generally be checked before testing accuracy.

Accuracy requirements and geometrical and practical tests referring to BS 3800, for general and normal precision machines.
