  • Combination 2-plane CNC positioning grinder with CNC positioning drill
    Patent number: 6722959
    Abstract: A glass plate tooling apparatus has independently driven loading and unloading tools which presents raw workpieces to, and removes finished workpieces from a centrally located machining station. The machining station holds the workpiece in a fixed orientation on first and second planes. Machine tools, such as a grinder apparatus and a drill apparatus are independently movable on the first plane to engage with and tool the workpiece. The machining station rotates to provide tool accessibility on a third plane.
