CONCORD DK-7740C-C WIRE EDM MACHINE

Technical Description

The CONCORD DK-7740C-C is a precision CNC wire electrical discharge machine designed for high-accuracy metal cutting applications. It features X-axis travel of 15.75 inches (approximately 400mm) and Y-axis travel of 19.69 inches (approximately 500mm), providing adequate workspace for medium-sized workpieces. The machine utilizes advanced CNC control technology to deliver consistent, repeatable cuts with tight tolerances typical of wire EDM systems. This compact wire EDM employs a thin wire electrode, generally ranging from 0.15-0.2mm in diameter, to perform precision cutting through electrical discharge erosion. The CNC control system enables multi-axis simultaneous machining, allowing for taper cutting and complex geometries. Standard specifications for machines in this class typically include cutting speeds of 120-150 mm²/min, cutting accuracy of ±0.015mm for straight cuts, and surface finish capabilities of Ra 1.0-1.2 micrometers. The machine accommodates workpieces with maximum thicknesses around 150-200mm and can achieve taper angles up to ±30 degrees depending on thickness. It operates on standard three-phase 380V/50Hz power supply with moderate power consumption suitable for shop floor installation. The compact footprint and controlled work tank dimensions make it ideal for job shops and precision manufacturing facilities requiring high-accuracy cutting without extensive floor space requirements. Automatic wire threading, adjustable wire tension, and precision linear guideway systems ensure reliable operation and minimal maintenance requirements.
