Disc Spring Special Features Three piece, face gear coupling allows the tool disc to be indexed without lifting. It also ensures high repeat positioning accuracy and rigidity. Parallel index cam mechanism allows fast and smooth indexing of heavy tool discs. Computer generated cam-profiles ensure shock-free indexing action. Totally enclosed, robust mechanism with oil bath lubrication. Electrical elements conveniently located in a separate area, free from oil and coolant. Bidirectional working; can index in either direction to allow shortest indexing time. Principle of Working Fixed Coupling (7), Indexing Coupling () and Sliding coupling (9) form a set of piece coupling. Axial movement of Sliding Coupling (9) is controlled by Drum Cam (6). Movement of Indexing Coupling () is controlled by Parallel Index mechanism () & (5). Torque Motor (1) drives the Cam Shaft () through a system of gears. Cam Shaft indexes the Follower Shaft (5) through a Parallel Index Drive mechanism. Cam shaft is also geared to the Drum Cam (6) which controls clamping and release of the piece coupling. One revolution of Cam Shaft completes one indexing cycle of declamping-indexing-clamping. Absolute position Encoder() gives feed back of the turret position. Turret clamp Switch() inspects the clamped position of the turret. 1 5

Motor must come to a physical halt within this angle. Otherwise the turret will get de-clamped and the proximity switch signal will be lost. It is therefore important to switch-off the turret motor in the fastest possible manner by using solid state relays. 10 7
