Introduction
Medium and large EDM machines are used in aviation, energy, and civil fields for key engine parts, housings, and difficult-to-process materials, as well as large-scale
It is an important equipment for precision machining of key parts. Its machine tool structure and precision requirements are different from those of traditional single-column and double-column EDM machines.
The bed is different, requiring a new structure and higher precision. The EDM forming machine tool with a moving beam gantry structure breaks through the traditional double-column EDM
The limitations of the EDM forming machine in terms of Y-axis travel and overall machine accuracy have effectively improved the EDM processing accuracy of medium and large parts.
This document makes the precision detection behavior of moving beam gantry EDM forming machine tools more standardized, which is conducive to improving the manufacturing quality of machine tools and promoting the industry
standardization.
Precision inspection of moving beam gantry EDM machine
1 Scope
This document specifies the geometric accuracy, positioning accuracy and working accuracy of the moving beam gantry EDM forming machine tool, and also specifies the accuracy related to the above
The tolerance value corresponding to the inspection item.
This document is applicable to the accuracy detection of gantry structure EDM forming machine tools with fixed worktable and movable crossbeam.
This document only covers the detection of machine tool accuracy, and is not applicable to machine tool operation tests (vibration, abnormal noise, creeping of parts, etc.) and other
Checks on parameters (such as speed, feed rate, etc.) are usually performed before precision testing.
