Claims
- 1. A process for machining glass, comprising the steps of:
- placing a carbide working surface of a solid tool against an area of a glass workpiece;
- wetting the working surface with a lubricant consisting essentially of a middle molecular weight petroleum distillate carrier, a complex mixture of esters, and a complex mixture of naturally occurring aromatic oils; and
- driving said wetted working surface with continuous motion and minimal pressure against said glass workpiece area.
- 2. A process for machining glass, comprising the steps of:
- placing a rotating carbide working surface subject to minimum pressure against an area of glass to be worked;
- wetting the region between the working surface and the area to be worked with a lubricant consisting essentially of a mixture of a middle molecular weight petroleum distillate, a complex mixture of synthetic esters, and a complex mixture of natural occurring, purified aromatic oils.
- 3. The process set forth in claims 1 or 2, wherein said carbide working surface is a double fluted drill ground with a plurality of adjoining point angles.
- 4. The process set forth in claims 1 or 2 wherein said working surface is driven at a speed on the order of hundreds of motions per minute.
- 5. The process set forth in claim 3 wherein the drill has a diameter between 0.125 and 0.018 inches.
- 6. A process for machining glass, comprising the steps of:
- driving a tool having a working surface of a material exhibiting a hardness greater than glass with continuous motion and minimal pressure against a glass workpiece; and
- wetting the region between said working surface and said glass workpiece with a liquid phase lubricant consisting essentially of a complex mixture of synthetic esters, a complex mixture of purified aromatic oils of plant origin arranged with a definite distribution, and a middle molecular weight petroleum distillate carrier.
- 7. The process of claim 6 wherein said tool is solid.
