Mitsubishi Electric Europe B.V. Mechatronics CNC Division

Everybody’s trained up to jump in when needed

The shop’s specialised knowledge is said to be the crucial resource for moulds and tools with the desired quality. The highly trained workforce and the machine park form a sound foundation for quality and flexibility. For instance, all toolmakers are able to operate any of the machines and process any of the workpieces. Each employee is solely responsible for his job, said to call for technical competence, offer the chance to work independently and demand a high degree of personal accountability. Recently, one machinist was concentrating more on wire-cutting with a Mitsubishi MV 2400 R, the owner said.

Moving forward with the next generation

For years, the company wire-cut tools on a Mitsubishi FA 20. Good care and regular service of the machine kept its performance tip top.

But even good things can be improved upon, the shop said. In 2012, Mitsubishi Electric introduced its MV wire EDM machines. The shop owner was said to be intrigued by the units. He realised it was time to move on with an investment that would boost the productivity of his EDM department, and soon pay for itself. The MV was said to immediately justify the investment because it offers better functionality, shorter throughput times than its predecessors and hence lower piece costs. The new generator technology also reportedly lowers energy and wire consumption. The MV is claimed to mark the entry level into the high-end class of wire-cutting machines for a modest price.

The improvement in performance, reduced wire consumption and energy savings were the decisive factors for selecting the unit, the shop owner said, noting that other features like the larger machining range and the footprint were also important.

The MV 2400 R was installed at the Lüdenscheid firm in autumn 2012 and has since been running in 1.5 shifts per day without any notable stoppages. During the machining of the very first workpieces on the MV, the new wire-threading system was fast: the FA 20 took an average of 20 sec for threading, the MV only 5 sec.
