Glass Fabrication

 

Glass Machining

Abrisa Technologies provides multiple technologies/processes to support your glass/optics shapes, surfaces, edging, and hole drilling requirements. Depending on glass types, thicknesses, hole diameter, and edge quality; Abrisa Technologies can choose between CNC machining, opposed edge drilling, or abrasive material removal or sandblasting to meet your specific glass fabrication requirements.

  • CNC Processing
    (Shapes, Notching, Slotting, Grooving, Step Surface):

    CNC machining can provide any custom shape with any type of ground or polished edging, including parts with holes, tapers, notches, slots, grooves, or stepped surfaces.

  • Drilling (Holes & Tapers):

    Abrisa Technologies provides multiple avenues to drill holes:

    • Through holes
    • Blind holes
    • Step holes
    • Countersink holes

    Hole parameters are only limited by the CNC machining capabilities stated above.

     

  • Countersink & Inside Dimension Seaming:

    Parts with holes, slots, or grooves can be tapered on both sides or seamed on the inside dimensions to improve inside edge quality. The only limitations are from the CNC machining capabilities stated above.

     

  • Circle Grinding:

    High volumes of circular parts can be quickly ground to precise diameters.

  • Grinding & Polishing (Buffing and Lapping)

    Parts with special surface or edge polishing requirements can be ground to size, rough surface ground (lapping), or smooth polished (buffing).

  • Sand Blasting (Surface Patterns and Logos):

    Portions of the part or the entire part can be sandblasted for a rough or cloudy surface finish or logos and patterns can be applied to the surface of the part. The inside or outside surfaces of tubing can also be sand blasted for a rough or cloudy surface finish. Sandblast grits available from 80-400.
