Machine combines wire EDM, waterjet technologies

September 24, 2009

Mitsubishi's MD+CELL combines the MD+PROII wire EDM with a Suprema DX44 waterjet for high speed and precision in one automated unit. The machine is designed to minimize operator intervention and maximize unattended run time for piece-part manufacturers.

The MD+CELL uses a Mitsubishi MELFA six-axis robot to transfer rough cut pieces from the waterjet to be finished on the EDM machine.

The waterjet includes an all-stainless steel work tank and utilizes 22-inch I-beam construction with 40 mm ball screws. Its Mitsubishi 700 Series CNC control delivers advanced programming capabilities for high-precision machining. The control is operated from a 15-inch waterproof screen, with improved graphics and NC design to simplify operation.

The MD+PROII wire EDM's stacked-filter design reduces floor space requirements by 20 percent, the company says. The machine's upper- and lower-head design improves durability and reduces setup and maintenance costs. It comes standard with 0.004 in. to 0.012 in. wire capable automatic threading and all-axis absolute control, which enables accurate positioning without returning to zero after power failure. The simplified auto-threading and wire drive systems reduce part costs and extend maintenance cycles.

The MD+PRO II's V350 II power supply with anti-electrolysis technology helps achieve top machining performance. PM4 (Power Master 4) has stepped shape capabilities, allowing multiple parts with different shapes and thickness to be machined without setting specific electrical conditions. SL (Step Less) Control improves accuracy for finishing step shape workpieces.
