Ultrasonic milling has proven to be an effective technique for improving titanium,
aluminum and stainless steel workability. Under the action of
ultrasonic milling, it has more advantage than the traditional
milling. In contrast to the effect of ultrasonic machining
aluminum, steel, stainless steel, titanium four metallic
materials.Improved surface quality of the most prominent is the
titanium and aluminum, can improve the cutting ability of the most
prominent is the stainless steel, the quality of the workpiece side
is the most significant improvement in steel. In addition, for
steel quenching after nearly HRC60, the traditional tool is
difficult of steel cutting and processing cost is high, only when
its hardness is higher than the work piece tool HRC25 above to
processing. However, on the basis of traditional tools added to
ultrasound, can greatly reduce the cutting of cutting resistance
and improve cutting surface quality, but also increase the service
life of the tool at least doubled.
Principle:
Ultrasonic machining process uses 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.
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
Applications:
applying in elaborate processing for various kinds of materials
especially fragile rigid material. The milling process by using
rotate milling cutter is suit for processing plane, groove, all
kinds of form surface (such as spline, gear and thread) and special
surface of mould.
