Benefits With the Stationary Sonic-Mill®
Process the work material is not stressed, distorted or heated because
the grinding force is seldom over two pounds. There is never any direct
tool-to-work contact and the presence of the cool slurry makes this
a cold-cutting process.
Summary The Stationary Sonic-Mill®
Process utilizes a power supply that converts conventional line
voltage to 20KHz electrical energy. This high-frequency electrical
energy is provided to a piezoelectric converter that changes high-frequency
electrical energy into mechanical motion. The ultrasonic motion
from the converter is amplified and transmitted to the horn and
cutting tool. This causes the horn and attached cutting tool to
vibrate perpendicularly to the tool face thousands of times per
second with no side to side motion. A recirculating pump forces
E/Z Pump™ abrasive, suspended in a liquid medium, between the
vibrating tool face and the workpiece. The abrasive particles strike
the workpiece at 150,000 times their own weight. These tiny abrasive
particles chip off microscopic flakes and grind a counterpart of
the tool face.
Rotary Processing Equipment
Benefits The combined action of the rotary ultrasonic
motion plus a water coolant produces a self-cleaning action that reduces
diamond tool binding. This enables fast, efficient cutting at a lighter
tool pressure than with conventional machining. Lighter tool pressure
is advantageous for drilling small diameter holes, long deep holes and
adjacent holes that are very close to one another. The rotary ultrasonic
action causes reduction in friction between the tool and the workpiece
which extends diamond tool life and reduces stress caused by conventional
diamond tool machining.
Summary The Rotary Sonic-Mill®
Process utilizes a power supply that converts conventional line
voltage to 20Khz electrical energy. This high-frequency electrical
energy is provided to a piezolectric converter that changes the
high-frequency electrical energy into mechanical motion. The ultrasonic
motion from the converter is amplified and transmitted to the
rotary spindle. This causes the diamond tool attached to the spindle
to vibrate perpendicular to the tool face thousands of times per
second, with no side-to-side motion.
The spindle speed is variable between 0–8,000rpm.
This rotation along with the ultrasonic motion enhances the cutting
action of the attached diamond-plated or impregnated tool.
