Quartz bar aligning

Quartz bars are the raw material for cutting of blanks. A good pre-alignment of bars is needed to gain blanks of high quality that show the desired temperature behaviour.

For aligning quartz bars in the saw, an X-ray measurement is required. Each bar is aligned individually since they are not exactly the same. An adhesive glue is applied to fix the bar after the measurement using UV-light, the so-called "UV curing".

Sawing of quartz bars is most effective when a high number of bars can be processed in one single step. Stacking of bars proves to be an efficient method for sawing up to 30 bars at the same time.
