On the level: An introduction to part leveling
Parts leveling eliminates the distortion effects of upstream processes
by Franck Hirschmann
When metal is formed or cut, stresses occur. All thermal cutting processes, from oxyfuel and plasma cutting to advanced laser systems, put stress into metal. The processes generate an enormous temeprature difference within the part, which leads to tensions in the material and distortion at the edges as the part cools. Even cold processes as punching and blanking with a press can release existing tensions in the material. The result is a part that may not be perfectly flat.
This is where hydraulic part levelers come into the picture. The process is straightforward and, if performed correctly, levels parts with high precision ...
