High Power Ultrasonic Milling Machine with Rotating Multi-blade Cutting Head for Higher Productivity

It mainly consists of an ultrasonic spindle system, a data acquisition system, and a coolant system. The ultrasonic spindle system comprises of an ultrasonic spindle, a power supply, and a motor speed controller.

The power supply converts 60 Hz electrical supply to high frequency (20 kHz) AC output. This is fed to the piezoelectric transducer located in the ultrasonic spindle.

The ultrasonic transducer converts electrical input into mechanical vibrations. The motor attached atop the ultrasonic spindle supplies the rotational motion of the tool and different speeds can be obtained by adjusting the motor speed controller.

Specification:

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

Applications:

1. 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.

2. Application area: machining industry, machine tool equipment manufacturing

3. Application occasion: manufacturing enterprise, universities and colleges, scientific research institution, mechanical equipment transformation industry
