Knuth 9 kVA ZNC-760 L Die Sinking Electric Discharge Machine 100116

Description

The die sinking EDM machines of the ZNC EDM series are used in mold and tool making to reproduce injection molds or matrices with high precision and surface quality. The series is characterized by high-quality components designed for continuous operation. The models have already proven themselves many times and offer excellent performance in every size. The desired working parameters for roughing and finishing can be stored in the control, as can the desired working depth. The table is positioned manually.

Features

• User-friendly CNC control assists the user in the selection of work parameters
• The machine frame design incorporates modern aspects plus many years of manufacturing experience
• X and Y- axes are equipped with preloaded ball screws for low maintenance and high precision
• The main axis is positioned by a precision spindle, which has its own lubricant circuit - ensuring constant temperature conditions at the spindle, minimum friction, and maximum precision
• The dielectric system is driven by a premium pump made by a renowned European manufacturer
• Machine operation is user-oriented and easy to learn
• Finely-incremented work parameters allow high powered material removal and finishing in one process
• Diagnostic information is very helpful
