Abstract
The glass sheet processing apparatus includes a sheet support stand which rotates the glass about a vertical axis and cutting and edging tools that move along linear axes generally perpendicular to the vertical axis. As the glass is rotated, the cutting tool moves towards and away the support stand to score the desired outline configuration of the glass part. The undesired trim portion of the glass is then removed. The glass sheet is then rotated and the edging tool is moved towards and away from the support stand to grind the periphery of the glass part to its final finished edge.
Claims11
A method of processing a sheet of material comprising:
- supporting said sheet to allow only rotational movement;
- rotating said sheet in a predetermined plane about a stationary axis of rotation;
- cutting said sheet during said supporting and rotating steps to define a part having a desired outline;
- and
- edging said part during said supporting and rotating steps.
