Abstract
This machine tool such as CNC edge grinding apparatus is an apparatus for machining small glass parts such as a side view mirror. For small parts, grind time can exceed by a considerable amount the load/unload time. This machine greatly increases the output of the system. It minimizes the waiting time by providing an auxiliary station for simultaneous unloading/loading while grinding. Controls integrate multiple axes, which are part of the holding mechanisms, with the linear axes of the grind head, to grind the part.
Claims13
An apparatus for machining a workpiece about three axes comprising:
- a tool for machining a workpiece;
- at least two holders fixed in position relative to each other such that a first holder is located in a first position remote from the tool and a second holder is located in a second position adjacent the tool, wherein the second holder retains a workpiece and operates in cooperation with the tool to machine the workpiece about three axes while the first holder is receiving a raw workpiece intended for machining;
- a rotating index table supporting the at least two holders, the index table operating to rotate the at least two holders such that, when the machining operation on the workpiece in the second holder is completed, the first holder retaining the raw workpiece is moved to the second position adjacent the tool and the second holder with the finished workpiece is moved to the first position remote from the tool, wherein the finished workpiece is removed from the second holder and another raw workpiece is positioned in the second holder while the workpiece retained in the first holder is being machined;
- and
- a controller for simultaneously controlling the table, the holders, the machining of the workpiece and the positioning of the tool and at least two holders to machine the workpiece on three axes.
A process for machining a workpiece about three axes comprising the steps of:
- a) providing a tool for tooling a workpiece;
- b) locating a first workpiece proximate the tool and machining the first workpiece about three axes with the tool while, at the same time locating a second raw workpiece in a position remote from the tool;
- c) after completion of machining of the first workpiece, removing the finished workpiece from its position proximate the tool and locating the second raw workpiece proximate the tool for machining;
- d) machining the second raw workpiece about three axes and, at the same time unloading the finished workpiece and locating a new raw workpiece in a position remote from the tool;
- e) simultaneously controlling the positioning of the workpieces, and the machining of the workpieces;
- and
- f) repeating steps b-e above.
