Planing machine

The planing machine from the 1920s is a machine tool used for planing work on long iron work pieces. The machine brings the work pieces into the desired shape with a chisel, which chips off the superfluous material. The work piece is fixed onto a sled, which is put in motion by a transmission. The sled delivers the work piece underneath the chisel, which planes the work piece into the desired form. After each planing stroke, consisting of a working stroke and a return stroke, the chisel is shifted sideways and the process begins over again.
The sounds of the planing machine are made by the planing and chipping, through the friction of chisel and metal.
The machine was in use in the Jacob Döring Tool Factory in Hagen in the 1920s. At first it was driven by a transmission using water power. Later it was powered by an electric motor.
It is currently in the possession of the Technology Museum Freudenberg (Germany, North Rhine-Westphalia) and is activated for demonstration purposes.
