ABSTRACT:
A clamping fixture adapted to securely hold narrow workpieces for grinding in a double disc grinder is disclosed, the fixture including a moveable frame mounted on a support plate disposed within the moveable frame. The support plate has a workseat affixed to one end while the moveable frame carries a pivotal clamp positioned to be drawn into engagement with a workpiece disposed in the workseat by pulling movement exerted on the moveable frame to produce the clamping action. Both the moveable frame and the support plate are of reduced section in the portions thereof which are moved into the grinding zone during grinding in order to maximize the overall rigidity of the fixture against grinding-induced forces so that accuracy of the grinding process is enhanced.
