The drilling device model is a simple drilling device that enables the automatic clamping and drilling of workpieces. After pressing the start button, cylinder A first clamps the workpiece. After clamping the workpiece, the drive motor M1 of the drilling machine is switched on and the machine is then moved into the workpiece via cylinder B. After the drilling process is complete, cylinder B retracts first and then cylinder A retracts again after the motor is switched off.
