Wire EDMs Offer Expanded Z Height
Sodick’s AQ750LH and AQ1200LH model AQ series wire EDM machines feature an expanded Z height and linear motor drive technology.
Sodick’s AQ750LH and AQ1200LH model AQ series wire EDM machines feature an expanded Z height and linear motor drive technology. UV-axis travels enable full Z-axis capacity machining of extreme taper angles ranging to 45 degrees. The UV travels are larger than the XY movements so that tapering can be performed beyond the normal X-Y travels of the machine. They are well-suited for automotive molds and dies, aerospace, and energy applications, including parts such as turbine hubs, aerofoil vanes, instrument panels and bumpers.
The fixed-table AQ750LH model features a 24" cutting capacity. Standard features include an L-cut wire chopper, high speed generator, low-maintenance tank seal, multi-filtration system, wire jumbo feeder, super jet AWT and vertical sliding tank door. X- and Y-axis travel measures 29.53" × 16.68". The AQ1200LH model also features a 24" Z axis and X- and Y-axis travel measuring 47.24" × 31.50".
Both models incorporate a control with collision protection to avoid operator error. This technology constantly monitors voltage in the axis drives, and stops the machine when voltage exceeds a predetermined load. The control also features automatic machining-condition selection based on a database that contains details on the best conditions for various wire diameters, workpiece materials and workpiece thicknesses.
Beryllium copper offers many benefts to the moldmaker and plastic injection molder, yet questions remain on how to best EDM it, which alloy to specify, where to use it, and is it safe to work with?
Modular workpiece fixturing plays a vital role in this shop’s quest to win larger, more difficult wire EDM jobs.
Originally, wire EDM had two things going against it. It was slow, and often it left an undesirable surface finish. In the last few years, wire EDM builders have fixed the speed problem. Now they're well on their way to fixing the surface finish problem.
