Glass Tube and Rod Cutting.

Diamond Saw Cutting Using CIT Machines and Wet Process

Glass Tube and Rod Cutting: The saw cutting is done using thin diamond wheels ganged together on an arbor. The lubricant being used in this process is water. This is a high-speed, high-volume process. This process is capable of cutting both tubing and cane.

Most common types of glass CIT cuts with this process are:

• KG-12
• Corning 8870 or equivalent
• G. E. or Osram 772
• Osram SG-80
• G. E. 180
• 7740 Pyrex
• High lead glass type 2795
• EN-1
• SG-773
• Schott 8487

Typical tolerances for this process are:

• The tubing or cane length for the cutting is 13.5” or 343 mm. CIT can cut longer length tubing down to this required length.
• The outside diameter of the tubing or cane runs from .045” (1.143 mm) to .150” (3.810 mm).
• The length of the cut part can run from .060” (1.524 mm) to 4.0” (101.60 mm).
• Tolerance of the length runs from .002” (0.050 mm) to .005” (0.127 mm). The outside diameter, inside diameter and length of the part being cut will determine this tolerance.
• Product is cleaned using our automatic washer, DI rinse tank and centrifugal dryer.

Score, Snap and Polish using CIT Machines

Finished product can be furnished with fire-polished (glazed) ends or as cut. This process is better suited for hard types of glass.

Typical types of glass CIT cuts with this process are:

• G. E. and Osran 772
• Osram 773
• 7740 Pyrex

Typical tolerance for this process are:

• Outside diameter from .050” (1.270 mm) to .200” (5.08 mm)
• The length range is from 2.0” (50.80 mm) to 54’ (1371.60 mm)
• Typical tolerance for length will range from .010” (0.254 mm) to .030” (0.762 mm)
• Fire polish can be performed per customer requirements

Statistical process control used on all critical parameters.
