Materials and Construction
Steel (machine construction steel)
The rollers of the round bending machines are made of steel with a strength of approx. 600–700 N/mm².
Sheet material 400 N/mm²
Machine data (max. sheet thickness) refer to sheet materials with a strength of 400 N/mm².
Cast construction
The lever plate shears of the HS and HBS types are executed in robust cast construction.
