Ingot removal machine is used to remove the ingot in the bodies of four different MAKITA hammer drills. The operator slides the tray out and puts the MAKITA body on the plug (appropriate for a given workpiece). He then inserts the tray in and pushes the START button. During the whole process, the tray is secured from unauthorised opening with an electromagnetic bolt, magnetic sensor and the pneumatic stopper cylinder (the rod is used as a locking pin). It is only possible to open the tray when the STOP button is pressed for longer than 2 s, after which the process is interrupted.

First of all, pneumatic shears are moved closer to the ingot in order to cut it off. Next, the shears are drawn in. The electrospindle is turned on and moves to the safe height with the aid of the pneumatic servo-motor with a quick (idle) movement. The spindle moves to the hydraulic damper and the working motion of the spindle commences (ingot milling) to the right distance (adjustable with a stop screw). After milling, the spindle moves upwards and stops. Then the tray is unlocked, it can be slid out and the ready workpiece can be taken out. The whole process cycle takes around 15 seconds.

The ingot removal machine is based on a frame welded from S235J0 steel. On the back of the frame, there is a power supply and control box with a valve system for pneumatic supply. The side covers are also made of S235J0 steel. The left cover is additionally equipped with polycarbonate viewing window. The front covers are made of plastic (polypropylene). The top cover and the opening cover are also made of plastic (polycarbonate). To keep good hygiene and avoid the cutter from clogging, the machine has an external, standalone chip dust collector connected directly to the power supply box. To make the transporting easier, the machine is equipped with swivel wheels with brakes.
