High Precision Non-Contact Type Ultrasonic Assisted Machining System For Brittle Material

Ultrasonic Machining (USM) also called as ultrasonic vibration machining is a machining process in which material is removed from the surface of a part by low amplitude and high frequency vibration of a tool against surface of material in the presence of abrasive particles.

Precision and surface quality of the finished product are important factors in the final product, especially in many drilling processes. Burrs are generally considered to be a negative result of the assembly process. One way to reduce or remove burrs in metal cutting and improve surface roughness is to use ultrasonic vibration during drilling.

Appropriate ultrasonic vibration can reduce burr height, drilling force and surface roughness more than conventional drilling. At the same time, in the workpiece vibration system, compared with the tool vibration system, higher surface roughness and higher drilling force are obtained.

The machining technology of SP TECH ultrasonic tool holders is mainly used to reciprocate the tool in a fixed direction at a high-speed frequency of 20,000 to 40,000 times per second by the resonance effect. The amplitude can make the cutting removal in the machining process more effective, therefore simultaneously reducing the cutting force and chipping of hard-to-cut materials as well as optimizing the machined surface.

Ultrasonic machining is commonly used in perforation, cutting, welding, nesting and polishing by reducing tool diameter, abrasive particle size and ultrasonic amplitude. It is suitable for turning, milling, drilling and grinding of diamond, glass, ceramics, tungsten carbide, titanium alloy and other materials.
