are composed of a frame, a lifting mechanism, a pressing tool and a power source. Besides the manually operated lever presses, mechanical presses
are also in part electrically operated. On spindle presses, a flywheel is kept in motion, on which an eccentric connecting rod is moved through use of a clutch. The connecting rod, which is moving up and down, operates the tool that starts the pressing process. A knuckle-joint press
pushes the workpiece together over a knuckle-joint, and a spindle press generates the desired pressure through an up and down movement of a rotating spindle. The most important and valuable component of a press is the actual pressing tool. This is a highly precise customised product, with which the actual workpieces can be remodelled. Through electrical support, mechanical presses
can achieve high clock rates. This is especially true for the knuckle-joint press, which is commonly used for stamping small workpieces. In order to ensure efficiency for this process, automatic assembly is necessary.
