Open type linear grating ruler / open grating ruler

Open type linear grating ruler / open linear grating ruler comprises a grating or strip grating and grating ruler reading head, and the reading head without mechanical contact. Open long grating linear grating is directly fixed on the mounting surface. Install the surface flatness directly affect the accuracy of linear grating.

Open type linear grating ruler / open linear grating design for machine tools and systems require high precision measurement

Typical applications include:

·semiconductor industrial measurement and production equipment

PCB circuit board assembly machine

·the ultra precision machine tool

·high precision machine tool

·measuring machine and comparator, measuring microscope and other precision measuring equipment
