Response FLUID POWER CONTROLS & SYSTEMS
Due to the High Response of Pacific Controls Hydraulic
Servo Systems together with the Servo
Drives and EDM Computers, Pacific Controls Company became a major supplier to multiple
U.S. EDM (Electrical Discharge Machining) Machines manufacturers.
In the EDMing process, electrical power, generated by
highly controlled electrical pulses, is applied
to the Gap (the space between the electrode and the work piece). When the conditions are favorable,
with every electrical pulse, an EDM Spark discharges in the Gap and a portion of the work piece is
Length of the sparks, aside of multiple electrical
parameters, controls the quality of the EDM sparks.
To achieve smooth and efficient EDM burn, the Servo System of High Response is essential.
In addition, during the EDM process, the “Gap
Conditions” change extremely rapidly since each
electrical spark, by eroding the work piece, generates debris that partially “fills” the EDM Gap.
To keep the EDM process efficient, every EDM spark needs to
be monitored and adjusted to
compensate for the presents of the newly generated debris.
Pacific Controls High Response Servo Systems, employed in
the EDM Systems, adjusts the length
of the EDM sparks according to the monitored EDM sparks electrical parameters. To achieve
efficient EDM burn, the required servo movement is usually only a fraction of the sparks maximum
Pacific Controls Micro EDMs, with force well above one ton,
execute servo moves in a sub-micron
region since the maximum length of the Micro EDM Sparks is set at 1.3 microns.
Pacific Controls designs and
manufactures its products from ground up, custom product oriented,
keeping their efficiency, reliability and ROI at the highest possible level.
the natural frequency of Pacific Controls High Response Electro-hydraulic Servo
Pacific Controls Super High Response Servo System has 4 mseconds
error, meaning length of the
lag between electric command & mechanical movement of the servo.
4 mseconds of course directly represents 250,000Hz.
