Recent Research Work Advances Machining Technology for High-end Optics

Technology

High technology industry is in constant need for high-performance workpiece materials. Particularly in optical industry the need for cost-effective industrial-grade technologies has intensified.

Tungsten carbide has been conventionally the workpiece; however, its machining to yield complex shapes has been associated with the tools used. Of note, tungsten carbide is remarkably hard due to which irrespective of the tool manufacturers use, they can’t avoid degradation. Diamond tools also suffer fast eroding, rendering them as not industrial-friendly. Moreover, the tool if inserted very deep beyond a point breaks the workpiece. All this makes grinding of the workpiece hardly effective in industry environments. A team of researchers has come out with a technology they call cutting-edge since it focuses on altering the chemical property of the work piece rather the tool.

Novel Grinding Technology Based on High-Frequency Excitation of Workpiece

The team from Kaunas University of Technology (KTU) has unveiled a new technology that uses ultrasonically-assisted grinding technique. They demonstrated that a high-frequency excitation of the workpiece, tungsten carbide, to achieve a useful state–plastic deformation state. The state is significant since it is when manufacturer can shape the workpiece without breaking. The high frequency enabled them to use the tool at better depth, thereby making the grinding of tungsten carbide efficient.

The work will pave way to new technology for manufacturers to advance the area of high-performance optics. This will open new avenue in the production of high-precision optics for smartphones, astrophysics applications, and the medical industry. The researchers have integrated precision grinding technology in an equipment for which they have filed a patent to the Lithuanian State Patent Bureau.
