The Body + Engine

A Drill press is usually powered by an electric motor, an induction motor. In this case the motor produces 350W and spins at 1300rpm.

The body of the dill press is made through steel casting, in 2 parts that are welded together. The top, where the belt and pulleys are, is made out of sheet metal. All the metal parts of the drill are connected to the body and the body is connected to the ground earthing system. This is necessary for the safety of the product (safety class 1). 

The top case covers the pulleys and belt. The case has to be closed when using the machine for safety reasons. But it can easily be opened by unscrewing a screw which holds the 2 half together. 

This is a close up of the safety switch installed on the top of the machine. The switch prevents the machine from functioning when the top case is open. On the picture you can also see the the hinges are welded to the case. (Probably to lower cost and reduce production time)

The engine is connected to the body of the press drill in a special way. It's hung an a hinge that is situated on one side of the body. It's designed that way so the V-belt van be tightened and discharched in (dis)assembly or use. 

The regulate the distance between the 2 centers of the pulley (is necessary when the belt becomes deformed over time), the engine can be rotated a little bit. By tightening the bolt (in red) the distance between the engine (circle) and the body (square) will enlarge and the tension the the belt will increase.
