One advantage of EDM is its process security. Once the job has been properly programmed and clamped, it will in all probability run smoothly, even for many hours and days. Even wire breakage is not an issue if the machines in operation have automatic wire threading. 5-axis machines finish the same job faster, but require much more elaborate programming. On top of this, there’s the multitude of tools that can cause difficulties during machining.

The Mitsubishi MV4800S Wire EDM is now capable of submerged cutting up to 505mm deep with the full support of the best auto threading system on the market today. The maximum workpiece dimensions are 1 250mm by 1 020mm by 505mm, the maximum workpiece weight is 3 000kg, the table dimensions are 1 080mm by 780mm and the XYZ travels are 800mm by 600mm by 510mm.

The Mitsubishi Electric MV4800S is ideal for machining large workpieces

With an annealing length of over 680mm, this system is capable of threading the maximum work-piece height both at the start point and through the gap if needed for a break point insert.

The MV4800S has added several new features such as a wide tank door window, a built in 25kg wire spool system and Thermal Buster which is a thermal stability system that circulates chilled dielectric fluid to key areas throughout the machine structure.

With advancements in machine construction and power supply technology, the MV4800S is sure to revolutionise EDM machining and increase your shop’s productivity.
