Makino HQSF™ Technology in Many Cases Can Eliminate the Need for Polishing
The High-Quality Surface Finishes (HQSF™)
additive technology from Makino improves
finishes using copper, high-grade graphite
(Poco-3, AFS) and medium-grade graphite
(Poco-2, Poco-200). Makino HQSF™
technology in many cases can eliminate the
need for additional bench work in certain
applications.
Makino's HQSF™ uses an environmentally safe powder additive (patented) that is
mixed with the dielectric fluid to improve
electrical conductivity for more consistent
discharging. This eliminates secondary
discharges that waste energy and allow
increased efficiency of the sparks, in order
to achieve a superior finish without a loss
in metal removal rates.
The additive-based technology has a major
impact on finishing time, with a 40 to 50
percent or better improvement of achievable
surface finish over conventional EDM sinkers
in similar applications. It is available for
all Makino Edge and EDNC s-version Ram EDM
machines.
HQSF™ is a remarkably practical method
of machining that combines micro-discharge
pulse control, high-response servo
technology and Makino's patented additive to
improve machine throughput. Makino's HQSF™
provides numerous benefits over previously
used silicon or chrome additives. This
technology is expected to find application
in many areas, including the machining of
ribs and other hard-to-polish shapes, such
as speaker grilles. Superior, more uniform
surface finishes with a shallow Heat
Affected Zone (HAZ) are achieved. Finishing
speeds are markedly faster than conventional
EDM, and stability of the machining process
is enhanced.
Equalized distribution in the dielectric
fluid is accomplished easily due to the low
specific gravity of the micro SC additives.
This results in superior sidewalls as well
as bottom surface finishes. Unlike other
additives, flushing is not necessary to
sustain even additive distribution on
sidewall areas. Another major improvement to
this technology is the elimination of a dual
dielectric system. A single dielectric
system consumes less space and requires less
overall maintenance than a dual dielectric
system. In addition, micro SC costs less to
use than other additives.
Makino SuperSpark™ Reduces EDM Roughing Time [back to top]
 Makino has developed a new breakthrough
in proprietary EDM technology that can
reduce rough machining time by up to 60
percent. This dynamic power supply
adjustment option for MGF control machines
can save an average machine shop as much as
$18,000 per year based on typical volume and
hourly rate estimates.
The result of years of EDM research and
development, machines equipped with
SuperSpark™ can reduce part-roughing time regardless of the shape, size or cavity depth.
