Test conditions for numerically controlled turning machines and turning centres - Geometric tests for machines with a vertical workholding spindle Ingestion-build-117251What is ISO 130412 about? ISO 130412 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 130412 explains different concepts or configurations and common features of NC turning machines and
