Glass

Glass

Description:

An amorphous form of silicon dioxide with and without modifications.  A hard and brittle, transparent material that acts as a substrate for various applications.  Specific types include fused silica, borosilicate glass and alkali-free glass.  Typical thicknesses are 0.3 - 5 mm with and without protectictive and optical coatings.

Major Considerations:

Cut quality:

  • Top-side and back-side chipping
  • Cut perpendicularity
  • Kerf side surface finish

Saw:

7122 , 7124 , High level of automation, process control tools and optimized blade size up to 5" for best Cost of Ownership.

Blade:

  • 2” and 4" Resin blades "Q" and "E" matrixes and Novus Sintered blades "I" series 
  • Diamond grit size: 15 - 53 microns (Resin) and 6 - 25 microns (Sintered)
  • Thickness: .002" - .012”

Process Parameters:

  • Feed rate: 2 - 15 mm/sec
  • Spindle speed: 2" : 18 - 30 krpm
                             4" :  8 - 16 krpm 
  • Dicing additives can reduce chipping and improve surface finish
