The Form P 350 die-sink EDMs from GF Machining Solutions feature precision-enhancing qualities and integrated technologies that are said to boost productivity and profitability.

Featuring a compact C-axis construction, fixed table and cast-iron frame, offers stability and force reduction to maintain a precise spark gap between the part and electrode. Regardless of part weight or dielectric volume, the machines deliver consistently high accuracies and surface finishes of Ra 0.1. Furthermore, integrated glass scales preserve repeatability and eliminate the need for recalibration and errors due to backlash and wear.
GFMS Form P 350 machines are equipped with the company’s intelligent power generator and Tecform module, which optimises each pulse to reduce electrode wear and generate high-quality surface finishes. Segment-dedicated technology eliminates the need to adjust the generator’s parameters.
The company’s iQ technologies control the erosion of graphite and copper electrodes, and help reduce costs. Real-time spark characteristic analysis and setting adjustment for pulse efficiency ensure wear-free spark erosion, precision, efficiency and greater control over the cost of the electrode, says the company.
Of note, the console’s AC Form HMI is based on Windows. Interactive graphics illustrate operations such as measurement and machining cycles for ease of use, while providing descriptions of machining targets, automatic selection of optimal technologies and dynamic parameter adaption.
GFMS Form P 350 machines are supplied with a four-position linear tool changer for System 3R macro tooling. An optional rotary tool changer can be specified that increases the number of electrodes to 160. The machines can also be paired with a System 3R WorkPartner 1+ robot for unattended night and weekend operations.
Offering X-, Y- and Z-axis travels of 350 x 250 x 300 mm, the machine accommodates workpieces up to 700 x 460 x 275 mm in size.

At Mattighofen, Austria-based GBM Kunststofftechnik und Formenbau GmbH, a newly installed Mitsubishi MV2400R Connect is making a genuine difference to this forward-thinking mould shop. Mitsubishi EDM machines are available in the UK from HK Technologies.

In total, some 35 injection moulding machines can be found in the halls of GBM. Be it parts for cars, medical devices or telecommunications equipment, there is very little that GBM cannot mould in plastic.
“Among the areas that is currently developing very strongly is vehicle charging equipment,” reveals managing director Roland Barth. “Extremely complex shapes are created for this, to produce wall boxes for example.”
As a result, the company recently purchased a Mitsubishi MV2400R Connect with travels of 600 x 400 x 310 mm in X, Y and Z, which is being used almost exclusively to produce injection moulds. In addition to machine’s fast cutting speed, the quality of the surfaces is an important factor for the Austrian firm.
“For us, the investment was important so that we could produce moulds faster than ever before, with surfaces that do not have to be reworked,” says Barth. “We want to continue growing and the machine will support us in our efforts.”
Barth deliberately opted for a larger machine, which is also equipped with the new D-CUBES interface. “Here I see a lot of potential for exploiting totally new possibilities in the future, particularly when producing moulds for our injection machines.”
