HOLLOW GLASS

CONICAL-TRUNK DRILL BITS

Used to grind the bottle mouths and the glass lids, either on their male or female variations. The degree of the cone shape normally used is 10%, as smooth as possible to guarantee the perfect fit and closure of the two pieces of glass.

FLATTING DISCS

To guarantee the perfect result for bottle mouths, we use flatting discs in automatic machines. There are different degrees of finish, but the most common one is D46. After grinding the edge of the bottle, we need to give the correct radius on the bottle mouth so that it is not too sharp, this is important so that it does not cut.

GROOVING

To groove is to draw forms on the surface of cups or decorative glass elements. We use grooving wheels in a V angle, uncentered angle, or concave in a U shape, to draw leaves, stems, and all kinds of decorative ornaments.

FLAT SURFACE GRINDING

Many times the hollow glass comes out of the mold deformed and we must grind the exterior faces by hand. The diamond has substituted the abrasive, making the job of grinding easier and more consistent.

These are pellet discs used for grinding, when we have to eliminate a lot of material, and resin discs for finish, that make the surface very flat and thin so that when joined with another surface, the glasses can stick to each other.
