Makino is proud to announce its latest Wire EDM technology
development, SurfaceWIZARD, which virtually eliminates witness lines.
SurfaceWIZARD is the newest control technology development
from Makino’s EDM R&D. This
technology provides exceptional surface quality in applications where the part
has variable shape thickness or sudden changes in thickness, such as a stepped
part. It will be an invaluable tool for
shops manufacturing parts for the aerospace, medical and injection mold
markets
Witness Lines
Historically, when stepped parts have been Wire EDMed the
process would leave a “witness” line at the transition from one step thickness
to the next. Many times the part would
have a taper with variations in straightness across the machined surface. SurfaceWIZARD virtually eliminates these
lines and has been shown to maintain part straightness within 5 microns in one pass
and within 2.5 microns in two pass machining.
SurfaceWIZARD technology has been developed for tool steels
up to 4 inches (100mm) thick, and will support 0.008” (0.020mm) and 0.010” (0.025mm)
diameter wires with one and two pass conditions. This technology was developed specifically
for use in poor flushing conditions where the nozzles cannot be sealed on the
work surface. The technology is
available as a standard technology on all Makino SP and U series Wire EDMs with
the MGW-S5 control.
Demonstrated at
Die/Mold Expo
The new SurfaceWIZARD control will be demonstrated at the
Makino Die/Mold Expo and EDM Forum to be held September 25 through September
28, 2007 at the Makino Die/Mold Technical Center in Auburn Hills, Michigan.
