Bench Top Rubbing Machine


Model: HO-IAD-BTR-02
Specially designed for LCD and LCoS R & D Labs
Motorized linear stage of maximum travel 300mm

Rubbing Machine has been developed for LCD R&D Labs. The system is intended for tracing grooves on the polyimide to orient the liquid crystal molecules. The grooves are made using a special rubbing cloth having depth of a few Angstrom. The substrate is held by a vacuum chuck for which a vacuum pump is included and integrated with the system. Maximum size of glass substrate which can be loaded in Model: HO-IAD-BTR-02 is 200mm diameter. The substrate along with vacuum chuck is held on a rotation stage so that it can be rotated and positioned at any required angle from ±20 degrees for various rubbing orientations.

The system has been developed as a standalone unit in which speed of the spindle and speed of the substrate can be varied.
