High Frequency Electrical 20KHz Ultrasonic Milling Machine With Multipoint Blade

20KHz Ultrasonic Milling Machine with Multipoint Blade Tool Prominent Workpiece Surface Quality and Structural Integrity

With the continuous development of industry, the request of machining spare parts is higher. With the development of high speed spindle technology and ultrasonic power supply technology, the ultrasonic milling process gathering ultrasonic high frequency vibration and spindle rotating in high speed is regarded as the pioneer of high precision and high efficient process technology, applying in elaborate processing for various kinds of materials especially fragile rigid material. The milling process by using rotary milling cutter is suit for processing plane, groove, all kinds of form surface (such as spline, gear and thread) and special surface of mould.

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:

1. Virtually any hard material can be machined
2. Little heat is produced
3. 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.
4. good surface finish and higher structural integrity is obtained
