Stable Amplitude Ultrasonic Drilling Process for Yttria and Sapphire

The excellent ultrasonic control technology can ensure the stability of long-term machining. Frequency scanning and power setting can be completed automatically by controller to improve productivity. The tool oscillates at a frequency of approximately 20 kHz by a piezoelectric sensor and an electric oscillator. The tool forces the abrasive grit to normally impact the work surface in the gap between the tool and the workpiece to machine the work surface.

It works in the same way as ultrasonic welding. This process uses ultrasonic waves to generate low-amplitude high-frequency forces that act as a driving force for the abrasive. This high frequency vibration transfer to the abrasive particles is contained in the abrasive slurry. This causes the abrasive particles to be indented to the brittle workpiece and removed from the contact surface.

Ultrasonic Machining is a new mechanical machining process, which can enhance the milling and drilling performance by high frequency micro vibrations.

Ultrasonic milling has proven to be an effective technique for improving titanium, aluminum and stainless steel workability. Under the action of ultrasonic milling, it has more advantage than the traditional milling. In contrast to the effect of ultrasonic machining aluminum, steel, stainless steel, titanium four metallic materials.Improved surface quality of the most prominent is the titanium and aluminum, can improve the cutting ability of the most prominent is the stainless steel, the quality of the workpiece side is the most significant improvement in steel. In addition, for steel quenching after nearly HRC60, the traditional tool is difficult of steel cutting and processing cost is high, only when its hardness is higher than the work piece tool HRC25 above to processing. However, on the basis of traditional tools added to ultrasound, can greatly reduce the cutting of cutting resistance and improve cutting surface quality, but also increase the service life of the tool at least doubled.
