At the UK’s largest machine tool show earlier this year, NCMT showcased two Makino EDM machines: the U6 H.E.A.T. Extreme wire EDM; and the EDAF3 die-sink model. The MACH 2024 exhibition proved the perfect platform to demonstrate the advantages of these Japanese-designed machines.
In addition to using standard wire from 0.1 to 0.3 mm, NCMT says that investing in the Makino U6 H.E.A.T. Extreme wire EDM makes it optionally possible to run the largest diameter wire (0.4 mm) of any machine on the market. The wire is coated and distinct from the uncoated brass wire common across industry.
The extra wire thickness, together with the use of a second booster generator in the machine, allows two to three times higher productivity and heavier duty machining compared with using a standard 0.25 mm consumable. Thicker wire also allows a slower unspool speed, so there is no increase in wire consumption rate.
Visitors to the NCMT stand could also see Makino’s EDAF3 die-sink EDM with its rigid, precise structure and integral thermal cooling of the Y- and Z-axis cast components to ensure long-term accuracy. Table size is 700 x 500 mm, while the dielectric reservoir is built into the base casting of the machine to improve thermal stability and minimise the machine’s footprint. The working volume is 450 x 350 x 350 mm, while the maximum workpiece weight is 800 kg.
Free access to the working area is courtesy of a programmable drop-tank. Users can extend unattended machining with automatic electrode exchange and automated workpiece delivery and removal options. A high-precision C-axis head is an additional feature. Machine shops can use electrodes weighing up to 75 kg.
