JNS Glass & Coatings 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; we  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.

Minimum Thickness: 0.76 mm [0.030”] Maximum Thickness: >25.4 mm [1.0”] Tolerance: ±0.508 mm [±0.020”] up to ±0.127 mm [±0.005”] Minimum Size: 76.2 x 76.2 mm [3” x 3”] Maximum Size: 3,048 mm x 1,524 mm [120” x 60”] Minimum Hole Size (Diameter): 0.76 mm [0.030”]

Drilling (Holes & Tapers):

We have many means to drill holes:

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

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.
Minimum Thickness: 0.508 mm [0.020”] Maximum Thickness: 25.4 mm [1.0”] Tolerance: ±0.254 mm [±0.010”] up to ±0.127 mm [±0.005”] Minimum Diameter: 6.35 mm [0.250”] Maximum Diameter: 304.8 mm [12”]


If you can draw it, we can sandblast it. A CNC sandblasting machine is used to create patterns from stock designs or your own drawings.  We also sandblast and inventory full sheets that can be fabricated down to your custom size.

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.
Minimum Thickness: 1.1 mm [0.043”] Maximum Thickness: 25.4 mm [1.0”] Minimum Size: 25.4mm x 25.4 mm [1” x 1”] Maximum Size: 2336 mm x 3657 mm [92” x 144”] Maximum Tube Length: 812.8 mm [32”]
