Development and Processing Testing of Precision WEDM Tool for Artificial Marble
Aiming at the problems of high energy consumption,large pollution,long cycle,large internal residual stress,easy deformation and decreased insulation after using working fluid,a precision WEDM tool for mineral castings was developed.The machine tool met a series of testing requirements of the group standard of TCMTBA 1010-2021.After one year of normal operation,mineral casting and cast iron machine tools are selected for cutting 100 mm thick workpieces with 8 A high current and 40 mm thick workpieces with narrow pulse width.The results show that under the same processing parameter conditions,mineral wire-casting machine tool have less energy leakage during high current cutting,smoother walking speed,and higher cutting efficiency than cast iron machine tool.The waveforms between poles of the cast iron machine tool will be distorted when the tool is repaired at 1 μs pulse width,and the tool is unstable,while the mineral casting machine tool can still repair the tool normally at 0.5 μs pulse width,indicating that mineral castings machine tools have obvious advantages in large energy output and narrow pulse width output due to their good insulation properties.
