What is BS 6101-2 - Accuracy of ball screws about?
BS 6101-2 is the second part of the BS 6101 multi-series that discusses machine tool ball screws.
BS 6101-2 is applicable to re-circulating ball screw assemblies having the shafts and nuts manufactured from hardened steel.
BS 6101-2 specifies requirements for accuracy and describes geometrical tests for re-circulating ball screws for use in machine tool applications.
Note: BS 6101-2 does not apply to test the running of the machine tool.
Who is BS 6101-2 - Accuracy of ball screws for?
BS 6101-2 on machine tool ball screws is useful for:
- Manufacturers/suppliers of hardware tools
- Designers of machine tool ball screws
- Quality control personnel
- Testing and inspection personnel
Why should you use BS 6101-2 - Accuracy of ball screws?
Ball screws are prone to ball screw drunkenness i.e., they tend to deviate from the path they were drilled or screwed into.
BS 6101-2 helps with the verification of the accuracy of ball screw assemblies before mounting in the machine tool. The tests in BS 6101-2 can be applied in any order that is practicable and that makes for ease of mounting of instruments or gauging. BS 6101-2 also describes a method of measuring the error in the ball track.
Overall, the guidelines of BS 6101-2 help you to identify the ball screw drunkenness of machine tool ball screws. You can use the insights from these tests to design ball screws with minimum travel deviations.
