Every machine can be made up in different ways and according to different philosophies, as far as materials are concerned.
The most common building steel is carbon steel.
There are also alloy steel and strongly alloy steel that have resistance and impact strength at high levels, unlike carbon steel. These types of steel can be labelled as “noble-metals”: they contains a percentage of Carbon which is more or less high, and also Nickel, Chrome and Molybdenum, and can stand thermal treatment according to the stress to which the mechanical part are put through.
Tauring Group has always built every part of its machines in strongly alloy steel. The evidence is given by the fact that after many years of job, there still exists bending machines that properly work and customers really satisfied.
