GB/T 19361-2021Wire electrical discharge machines(unidirectional traveling type) - Testing of the accuracy (English PDF)

1 Scope

This document refers to ISO 230-1, ISO 230-2 and ISO 230-4 to specify general-purpose, conventional precision wire EDM machine tools (One-way wire type) geometric accuracy inspection, CNC axis positioning accuracy and repeat positioning accuracy inspection, processing inspection and circle inspection. This document also

The tolerance value corresponding to the above-mentioned inspection is specified.

This document applies to cross-sliding table type machine tools and double-column type machine tools.

This document only relates to the verification of machine tool accuracy, and it is neither applicable to machine tool operation tests (such as vibration, abnormal noise, component crawling, etc.).

Inspection is also not applicable to the test of machine tool performance (such as speed, feed, etc.). The above-mentioned inspection is usually completed before the accuracy of the machine tool.

This document specifies the terminology of the main parts of machine tools and specifies the naming of coordinate axes with reference to ISO 841.
