ZNC 540 EMD: 1,More than 20,000 units of document storage capacity are provided. Namely more than 20,000 different mold or customer numbering can be stored. 2,With mirror surface processing circuit, a true mirror effect can be achieved. Also, it is even better to use orbit processing and powder mixing processing 3,10 segments auto editing function. (1) Manual edit: edit the machining condition by experience. (2)AUTOZ auto edit: max. Depths, initial current and finished procession, machining area selection are provided, and then machining condition edit can be finished automatically. (3) Intelligent condition edit: electrode shape, electrode and work piece material, work piece section area and finished precision selection, depth setting area are provided, and then machining condition edit can be finished automatically. With either the three edit methods above, machining can be complete at a time by the way rough→moderate→fine 4,X.Y.Z axis coordinates are switch with metric and English system 6,If unstable, discharging condition is auto adjusted by modifying discharging efficiency and working time. After that, the condition will restore automatically. And it is also adjustable at any time. 5,"Auto arcing detecting function. If unsteady caused by arcing occurs, the computer will adjust machining parameters and rise jump up height, then normal condition would return. 7,It could set that after 2 10 times discharging (jumping up control), the electrode will be raised (safe height Z) to the set arbitrary position and the continue machining. This could achieve good slagging off performance for deep hole machining
