Cold Machining process:

Cold Machining process: A high quality thin film filter requires very careful production processes. Glass substrates with extreme precise geometric tolerance and high degree of surface polish are essential. 

Our strict material processing systems perform from the initial substrate cutting into components of a suitable size, the smooth lapping of main and edge faces to produce the component geometry, and the final polishing to meet the performance specifications. 

This high quality process results defect free surface and fine edge polishing, scratch free surface on all types of material, as well as exacting and repeatable dimensional results.

 EOC's material processing systems offer the ideal solution to overcome the problems which encountered in production. The qualified substrates always meet the stringent demands of our customers' applications.
