The ZNC-650 is a large-capacity ZNC die-sinking EDM machine for mold cavities and shaped features in electrically conductive workpieces. It provides 650 × 550 mm X/Y travel, a 1,000 × 600 mm worktable and a maximum workpiece capacity of 2,000 kg. X/Y positioning is manual and monitored through the three-axis digital readout, while the Z axis is servo controlled for the EDM cycle.
This model is intended for jobs that exceed the work envelope or load capacity of the ZNC-540 but do not require programmed X/Y interpolation. Its 50 A power supply is published with a maximum material removal rate of 580 mm³/min under reference conditions. Actual output and finish must be evaluated against the electrode, workpiece and cavity requirements.

Model Selection Guidance
Choose the ZNC-650 when the job requires up to 650 × 550 mm X/Y travel, a workpiece weight of up to 2,000 kg or an electrode weight of up to 150 kg. If a 500 × 400 mm work envelope and 1,200 kg workpiece capacity are sufficient, compare the ZNC-540. For 700 × 600 mm travel, a 300 kg electrode capacity or a higher-current generator option, compare the ZNC-700.
The ZNC-650 retains manual X/Y positioning. If the application requires programmed X/Y/Z movement, interpolation or repeatable multi-cavity positioning without manual table setup, compare the CNC die-sinking EDM series.
Performance Conditions
The published 580 mm³/min removal rate, Ra 0.2–0.5 µm surface finish and 0.5–0.8% electrode wear ratio are HarsMarg reference values for the stated 50 A configuration. Actual results vary with workpiece and electrode materials, electrode area and geometry, polarity, discharge settings, cavity depth, dielectric condition, temperature and flushing method. These values are not simultaneous results or unconditional guarantees.
