TOPSCNC DK7750ZAC WIRE EDM MACHINES

Technical Description

The TOPSCNC DK7750ZAC is a precision CNC wire EDM machine engineered for high-accuracy metal cutting applications. This machine features X-axis travel of 19.69 inches (500mm) and Y-axis travel of 24.80 inches (630mm), providing substantial workspace for complex machining operations. The system incorporates a DQE-DC-01 controller managing 4-axis simultaneous control with a minimum control pace of 0.001mm, enabling exceptional dimensional accuracy of ≤0.015mm. The machine utilizes molybdenum wire electrodes ranging from φ0.15mm to φ0.2mm (recommended φ0.18mm) with adjustable feed rates from 1 to 11.4 m/s. Maximum machining speed reaches ≥220 mm²/min under standard conditions, with surface roughness achieving Ra≤2.5μm in one pass and improved finishes with multiple cutting passes (Ra≤1.1μm for three passes). The DK7750ZAC accommodates workpieces up to 500mm thick with a maximum workpiece weight of 1600kg on its 500×630mm table. It features a 60-degree maximum taper angle per 100mm thickness, making it suitable for precision mold making and complex geometric cutting. The machine operates on 380V, 3-phase, 50Hz power supply with maximum working current of 10A and power consumption of 0.7Kw. It includes a 90L water tank with paper filter or Italian pump filtration system and employs JR3A work liquid for optimal cutting performance and wire preservation. The complete machine weighs approximately 2800kg with dimensions of 2300×2100×2000mm.
