Non-Contact Power Transmission Technologies Ultrasonic Assisted Machining

Principle :

Rotary ultrasonic machining (RUM) is a mechanical type of nontraditional hybrid machining process that has been utilized potentially to machine a wide range of latest and difficult-to-machine materials, including ductile, hard and brittle, ceramics, composites, etc. In RUM, the basic material removal phenomenon of ultrasonic machining (USM) and conventional diamond grinding amalgamates together and results in higher material removal rate (MRR), improved hole accuracy with superior surface finish.

Specification:

Resonance point amplitude: 10um or more;

Speed: 3000 r / min or less

Matching tool: carbide end mill head Φ2-Φ13; disk cutter Φ50;

Power: 500W

Advantages:

1. The process is non-thermal, non-chemical, and non-electrical, leaving the chemical and physical properties of the workpiece unchanged. This low-stress process translates into high reliability for your critical applications.

2. Multiple features can be machined at the wafer or substrate level simultaneously, and the process is scalable. Our process is often the highest quality and lowest cost solution.

3. Ultrasonic machined features have vertical side walls, enabling you to preserve valuable space for your designs that translate into higher productivity.

4. The process integrates well with semiconductor and MEMS processes. Machined features can be aligned to previously patterned, machined, or etched substrates.

Applications:

1. Hard and brittle materials can be machined like tungsten carbide, diamond and glass. These are difficult to machine in conventional m/c-ing process.
2. Wire drawing dies of tungsten carbide can be drilled by this process.

3. Circular as well as non-circular holes can be done with straight or curved axes.
4. It has been proved successful in machining geranium, silicon quartz and synthetic ruby etc.
