What is ISO 13041‑2 about?
ISO 13041‑2 is part two of the multi-series standard that specifies, with reference to ISO 230-1 and ISO 230-7, the geometric tests for general purpose normal accuracy numerically controlled (NC) turning machines and turning centres with vertical workholding spindles, as well as the corresponding applicable tolerances.
ISO 13041‑2 explains different concepts or configurations and common features of NC turning machines and turning centres with vertical workholding spindles. It also provides a terminology and designation of controlled axes.
ISO 13041‑2 helps you improve and verify the accuracy of the turning machines and turning centres with vertical work spindles.
NOTE- ISO 13041‑2 does not apply to the operational testing of the machine (e.g. vibration, abnormal noise, stick slip motion of components) nor to machine characteristics (e.g. speeds, feeds). Tests not concerning the geometric accuracy of the machine are dealt with in other parts of ISO 13041.
Who is ISO 13041‑2 for?
ISO 13041‑2 on the geometric tests for general purpose normal accuracy numerically controlled (NC) turning machines and turning centres with vertical workholding spindles is useful for:
- Turning machines and turning centres designers
- Turning machines and turning centres manufacturers
- Industries using turning machines and turning centres
Why should you use ISO 13041‑2?
The objective of the ISO 13041‑2 is to provide information as wide and comprehensive as possible on geometric tests which can be carried out on turning machines and turning centres with vertical work spindles for comparison, acceptance, maintenance, or any other purpose.
ISO 13041‑2 provides geometric tests for workholding spindle or table, linear axes X and Z, cross-rail movement, tests related to Y-axis, tool holders and tool turrets, and power-driven tool holding spindles.
ISO 13041‑2 helps you improve and verify the accuracy of the turning machines and turning centres with vertical work spindles.
What’s changed since the last update?
BS ISO 13041‑2:2020 is the second edition that cancels and replaces the first edition (ISO 13041-2:2008), which has been technically revised. The main changes compared to the previous edition are as follows:
- The categorization of machine size ranges has been abolished
- The discrimination of tolerances, if any, due to different machine sizes (diameter of chuck or workholding spindle) is expressed in the specific tests g1 to g21
- The tolerances given in the g-tests have been changed due to the absence of size categories
- The numbering of tests g1 to g21 has been changed
- Tests for horizontal rams have been removed because these are no longer in existence
- Former g1 test "checking of flatness of the workholding spindle" has been removed
- Terms in persian and Japanese have been added in Annex B
