JK400-CNC Small Discharge Machine

Compact Discharge Machine JK400-CNCFeaturesSmall unit (integrated) for minimal installation space!!Head travel type for maximized usability!!Work tank is double-door type for easy setup.Oil tank integrated inside for neat appearance.Domestic discharge machines raise discharge amperage (IP) by electrode size to increase speed.Discharge conditions are subdivided by electrode size and type to improve efficiency.Electrode size, type, and workpiece (steel, graphites, carbide, aluminum, etc.) are considered for inverse conditions.Discharge conditions optimized for maximum effects under the same conditions.Voltage-based discharge can be controlled by current, boosting speed for medium/large electrodes and through-holes.As shown in Figure 1, the gap between workpiece and electrode for discharge sparks is longer than 30–40V, slowing discharge speed.However, ACT incidence is low; longer gaps improve chip discharge, reducing ACR.In Figure 2, the discharge spark gap between electrode and workpiece is shorter than 50–60V, causing more sparks per area per unit time, resulting in uniform brushing and reduced over-cut under the same conditions.     Especially, mid-to-large discharges see significantly improved brushing speed.Developed for low GAP discharge machining (30–40V) to optimize discharge speed, brushing, and wear. The EDM system uses AI with 1/1000 ON/OFF control to minimize ACR and enable Low GAP machining (30–40V) for higher productivity.Dialog-style CNC EDM with no NC code numbers in program.First in domestic to develop program without NC code for easy operation by beginners.Fewer errors during discharge editing; errors shown on screen.Ten-step rough to finish processing with 600 stored discharge conditions for flexible control.Machining can be rough, semi-finish, or finish in 5 steps, with on-the-fly condition changes.LCD remote controlRemote with LCD displays X, Y, Z coordinates for easy setup and completion of discharge settings from the remote.More convenient for large workpieces; precise 1/1000 control.RACK ensures reliable communication and accurate discharge signaling with fast A/S via card-based PCB.Designed for ease of use; conversational programming available without NC code.
