Ultrasonic Grinding machine With Specially Coated Tools , Integrated Milling Machining

Specification:

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.

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
