Description: |
| The present application is a continuation-in-part of William D. Zettler, et. al., application filed 22 Jan., 1971, for Chip Guard for Machine Tools, which is now abandoned.
Abstract:
An automatically operated chip guard arrangement is disclosed in the environment of a multi-purpose horizontal spindle machine tool and is adapted to be mounted on the headstock surrounding the top and sides of the tool operator. The chip guard automatically extends into contact with a workpiece at the operating station and readjusts itself to changes in relative distance between the workpiece and the headstock. |
