GB/T 5291.1-2023Die sinking electro-discharge machines - Testing of the accuracy - Part 1: Single-column machines (cross-slide table type and fixed-table type) (English PDF)

1 Scope

With reference to ISO 230-1 and ISO 230-2, this document specifies the geometric accuracy inspection of general-purpose, conventional-precision electric discharge forming machine tools:

Inspection, CNC axis positioning accuracy and repeat positioning accuracy inspection and machining accuracy inspection: This document also specifies the standards corresponding to the above inspections:

difference:

This document applies to single-column machine tools of cross-sliding table type and fixed table type:

This document only involves the verification of machine tool accuracy, and is not applicable to machine tool operation tests (vibration, abnormal noise, crawling of parts, etc:) or its

Inspection of parameters (such as speed, feed rate, etc:), these inspections should usually be carried out before the accuracy inspection:

This document also specifies the terms used for the main components of machine tools, and refers to GB/T 19660-2005 named coordinate axes:

Note: In addition to terms expressed in ISO official languages (English, French), Appendix A gives Dutch, German, Italian, Swedish, Persian and Japanese text equivalent terms: These language standards are published by the Netherlands (NEN), Germany (DIN), Italy (UNI), Sweden (SIS), Iran (ISIRI) and Japan (JISC) national member bodies are responsible: However, only terms given in official languages are considered ISO terms:
