Bevels, Hole, and Notch Quality Standards

Bevels

  • Based on machine capabilities

  • Bevel width tolerance is +/- 3/32"

  • Bevel corner tolerance on 1 1/4" and above is +/- 3/16"

Holes

Hole location quality standards for glass

Location (See Figure 1):

  • Minimum distance from edge of glass: 6 mm (1/4") or 2x glass thickness, whichever is greater​.

  • Minimum distance between holes: 10 mm (3/8") or 2x glass thickness, whichever is greater. 

Location (See Figure 2-3):

  • Minimum diameter of circular holes: 6 mm (1/4") or the thickness of the glass, whichever is greater.

  • Any other holes: Required to have fillets. Fillet radius must be equal to or greater than the glass thickness.

  • Hole Dimensional Tolerance: ± 1.6 mm (1/16")

Location (See Figure 4):

Notch & Cutout Dimensional tolerance: 

  • ± 1.6 mm (1/16") for glass thickness less than 1/2"

  • ± 3 mm (1/8") for glass thickness 1/2" or greater
