SEIBU M75B WIRE EDM MACHINES

Technical Description

The SEIBU M75B Wire EDM machine is a high-precision CNC wire electrical discharge machining system designed for large workpieces, featuring an X-axis travel of 29.5 inches (749.3 mm), Y-axis travel of 19.7 inches (500.4 mm), and Z-axis travel of 12.5 inches (317.5 mm). This machine is engineered to provide exceptional accuracy with a pitch tolerance of ±3 microns, achieved through its rigid meehanite cast structure ensuring vibration-free cutting. It supports wire diameters ranging from 0.07 mm to 0.3 mm and includes an automatic wire feeder (AWF-4) for continuous operation. The M75B incorporates a FANUC 31iWB CNC control with a user-friendly graphical interface displayed on a 15-inch TFT LCD touchscreen, facilitating ease of programming and operation. It can handle maximum workpiece dimensions up to approximately 900 x 700 x 250 mm and supports workpiece weights up to 1,000 kg. The machine also features ±60 mm travel on the U-V axes for taper cutting up to ±10° on workpiece thicknesses of up to 300 mm, with an optional ±45° taper capability for smaller thicknesses. The M75B’s design emphasizes high material removal rates combined with precise taper and contour machining capabilities, suitable for complex and large-scale manufacturing tasks requiring meticulous accuracy. Its robust build, advanced control, and precision features make it suited for demanding applications in die/mold making and precision engineering industries. The machine's dimensions and weight approximate 2,280 x 2,200 x 2,155 mm and 5,100 kg, respectively.
