With 6000RPM tool speed Ultrasonic Milling machine, including tool
holder and digital generator
Ultrasonic machining, also known as ultrasonic impact grinding, is
a machining operation in which a vibrating tool oscillating at
ultrasonic frequencies is used to remove material from the
workpiece, aided by an abrasive slurry that flows freely
between the workpiece and the tool. It differs from most other
machining operations because very little heat is produced. The
tool never contacts the workpiece and as a result the
grinding pressure is rarely more than 2 pounds, which makes
this operation perfect for machining extremely hard
and brittle materials.

Ultrasonic machining process uses a power supply that converts conventional line voltage to 20KHz
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.
The advantages of ultrasonic machining over ordinary machining:
- Virtually any hard material can be machined
- Little heat is produced
- Since the motion of the tool is up-and-down vibration rather than rotation as in traditional machining, the holes cut are not limited to circular shapes but can be any shape.
Custom "cookie cutter" tools can cut complicated shapes.
- good surface finish and higher structural integrity is obtained
