How to reduce 50 hours down to a mere 30
A comparison was performed with complex workpieces of very similar design produced again and again for a longstanding customer. Clamped on the old unit, the workpiece took about 50 hours to reach completion. For its virtually identical counterpart, the new unit completed the process after only about 30 hours. “The first machine presentations by Mitsubishi Electric yielded very similar figures. But it was the precise confirmation of these data in our everyday work that really surprised us,” the owner said. In everyday manufacturing, it is not easy to produce comparable data. However, price calculation calls for reliable and realistic data, and the shop generates the data with its own methods. The economical wire consumption of the new unit is said to be very apparent on each job. As far as consumables are concerned, Huyghe estimates savings of about 40%.
Looking for the big payback like shops everywhere
The shop owner noted that on the issue of payback, which is so important for businesses and financiers, he couldn’t accurately quantify the savings due to the short period of use. “However, I expect the MV 2400 R to have paid for itself in our production shop after two to three years.”
The company suggested that wire-cutting will continue to grow in importance in the foreseeable future, as the tools for many branches of industry such as the automotive and electrical industries will become increasingly complex. The demand for modular tools will thus grow. This is a task in which EDM machines with their technological advantages will truly come into their own. Particularly when one considers that such machines are capable of cutting tools directly out of hardened materials.
