Latest Patents

Duran's latest patents include an "Ultrasonic drilling apparatus" and an "Abrasive slurry composition for machining boron carbide." The ultrasonic drilling apparatus is designed to be attachable to an ultrasonic drilling machine for drilling deep holes in very hard materials, such as boron carbide. This apparatus utilizes a hollow spindle attached to the output horn of the ultrasonic drilling machine, with a hollow drill bit at the opposite end. A housing surrounds the spindle, forming a cavity for holding slurry. During operation, slurry is provided into the housing and into the spindle through inlets while the spindle is rotating and ultrasonically reciprocating. This design allows the slurry to flow through the spindle and the hollow drill bit, cleansing the cutting edge of the bit during drilling operations.

The abrasive slurry composition is particularly suited for drilling or machining boron carbide. It consists of a suspension of boron carbide and/or silicon carbide grit in a carrier solution, which is a dilute solution of alkylaryl polyether alcohol in octyl alcohol. The alkylaryl polyether alcohol acts as a wetting agent, improving the capacity of the octyl alcohol to carry the grit in suspension without significantly increasing the viscosity of the carrier solution.
