Pyrex Glass drilling, cutting, grinding
Greatglas uses diamond core drills to drill precise holes in flat and cylindrical glass from 0.10" to 1.00" diameter. These holes can be fire polished after they are drilled for added smoothness.
We also can make holes in cylindrical glass under heat with graphite punches from 0.10" to 2.00" diameter.
Using precision diamond water cooled saws, we can wet cut glass cylinders and flat glass leaving a smooth square surface.
Greatglas can grind the open ends of Pyrex glass cylinders to a length tolerance of +/- 0.005".
On glass cylinders, both ends would be ground square and in parallel.
Greatglas can fire polish the ends of ground cylinders to give them added smoothness and roundness for glass that goes into metal fittings.
