This document was first published in.2003, and this is the first revision.IntroductionIn order to distinguish between single-column and double-column EDM machine tools, GB/T 5291 consists of two parts. --- Part 1.Single-column machine tools (cross table type and fixed table type). The purpose of this document is to enable regular precision and general Standardization of inspection methods for electric discharge forming machine tools (cross table type and fixed table type). --- Part 2.Double-column machine tools (moving spindle head type). The purpose of this document is to specify general purpose and conventional precision electrical discharge Inspection methods for forming machine tools (moving spindle head type). The tolerances of G1, G2, G3, G5, P1, P2, P3 and P4 in this document have been modified according to GB/T 5291.2-2003. The machine tool axis name in GB/T 5291.2-2003 has been modified according to the provisions of GB/T 19660-2005. Due to the limited applicability in the current market, the cross table type machine tool (3.2 of GB/T 5291.2-2003) was deleted. due to At present, the applicability of T-slots of typical machine tools on the market is limited, so the following inspection of GB/T 5291.2-2003 is deleted. G9 "workbench reference Straightness inspection of T-slot or datum plane in X direction" and G10 "parallel between table datum T-slot or datum plane and X-axis movement degree check". Precision inspection of electric discharge forming machine tool part 2. Double column machine tool (moving spindle head type)1 ScopeWith 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 twin-column machine tools of the moving-spindle head 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 checking the accuracy. This document also specifies the terminology used for the main components of the machine tool. Refer to GB/T 19660-2005 for the naming method of the coordinate axes. NOTE.
