Interchangable CAMS

Interchangable CAMS

Interchangable CAMS - Cams are changed to set up an automatic machine tool for machining each different workpiece, or for each of two, three or several size groups of workpieces extending over the whole field of application of the machine.

In the first case, the interchangeable cam effects complex movements of the main working member (tool slide), required for form machining (single edge cylinder feed cam for the headstock of a Swiss type automatic), or it accomplishes a number of consecutive operations (or operation elements) performed by a single slide actuated by a single cam (cam of the turret slide in an automatic screw machine or of the tool slides in a Swiss type automatic). In this case the cam is of strictly individual design.

In the second case, the operating cycle is simple and, in addition to the interchangeable cams for setting up to the size group of workpieces, other devices are available for adjusting the stroke in setting up the machine for a definite workpiece within the size group. Interchangeable cams of this type are employed, for instance, for actuating the end tool slide of multiple-spindle automatics.
