Ultrasonic Grinding of Quartz Glass : Micro-channel Trochoidal Machining | Hantop Intelligence Tech.
HIT utilized ultrasonic machining module for micro-channel trochoidal machining of quartz glass. The high frequency micro-vibration helped reduce cutting forces, which made the max. size of edge-cracks around the micro-channels 2x smaller than that without ultrasonic. Easier inflow of cutting fluid brought better particle flushing, resulting in the reduction of tool wear.

Quartz glass has excellent electrical insulation property and is inert to attacks from all kinds of acids, even in very high concentrations, except for hydrofluoric acid. The material has high compressive strength, but also displays high hardness and brittleness. Defects on the surface may have a serious impact on its overall material strength.

Microfluidic devices are specialized in controlling, distributing, and manipulating gases and fluids in a network of micro-channels. It helps decrease energy consumption with minor sample handling, reduce process time for reaction and analysis, and improve the precision and flexibility of semiconductor manufacturing experiments.

However, due to the high hardness and brittleness of quartz glass, the risk of trochoidal grinding of quartz glass resides in massive chipping and edge-cracks around the micro-channels. The prevention of edge-cracks on the product is essential, for it may lead to turbulent flows within the microfluidic system. Therefore, it usually needs to go through etching for post-process to remove edge-cracks. The larger the cracks, the more time it will need to take to remove the edge-cracks during the etching process.

HIT ultrasonic-assisted trochoidal machining of quartz glass helped reduce cutting forces. This made the maximum size of edge-cracks 2x smaller than that without ultrasonic. The tool constantly lifting from workpiece allowed for easier inflow of cutting fluid, which not only brought better particle flushing but also less tool wear.
