What is ISO 6481 - Test conditions for broaching machines about?
ISO 6481 specifies, with reference to ISO 230-1, the geometric tests on surface type broaching machines with vertical Z-axis providing the main cutting motion. ISO 6481 specifies the applicable tolerances corresponding to the tests mentioned above for normal accuracy vertical surface-type broaching machines.
ISO 6481 explains different concepts or configurations and common features of vertical surface type broaching machines. ISO 6481 provides related terminology and designation of axes. ISO 6481 deals only with the verification of the accuracy of the broaching machine.
Note: ISO 6481 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.
Who is ISO 6481 - Test conditions for broaching machines for?
ISO 6481 on test conditions for broaching machines is useful for:
- The automotive industry
- The heavy engineering industry
- Manufacturers of broaching machines
Why should you use ISO 6481 - Test conditions for broaching machines?
The object of ISO 6481 is to supply information as wide and comprehensive as possible on tests on vertical surface type broaching machines which can be carried out for comparison, acceptance, maintenance or any other purposes.
A broaching machine is a tool used to finish surfaces by drawing or pushing a broach cutter completely over and past the surface. A broach is made up of a row or rows of cutting teeth that are graded in height from the teeth that cut first to the teeth that cut last. ISO 6481 establishes the tolerances for the test results corresponding to general purpose and normal accuracy vertical surface type broaching machines.
What’s changed since the last update?
BS ISO 6481:2019 supersedes ISO 6481:1981, which is withdrawn. BS ISO 6481:2019 includes some technical changes with respect to ISO 6481:1981. These include:
- The title has been changed
- The document's format has been aligned with new published ISO/TC 39/SC 2 documents
- Some terms have been changed and equivalent non-formal terms in more languages have been added to Annex A
- All diagrams have been regenerated
- Old references to ISO/R 230:1961 have been changed to ISO 230-1:2012 and all observations have been updated accordingly
