Two columns frames are used in all applications where is necessary guarantee an extreme stiffness and a perfect alignment among press spindle and tools.
The advantage of the use of two columns frames is a robust structure with a narrow footprint. This kind of frame is usually utilised in assembling operations or metal forming such us
stamping, pressing, coining and more. Two plates, upper and lower, are made in carbon steel C45 in normalized condition, the surfaces is grind with a grade of roughness of 0,6. The lateral two columns are made in case hardening steel 18NiCrMo5 and the surface after case hardening and quenching reach an hardness of 60/62 HRC, further this, two columns are finished by grind and subsequently lapped. The two columns frame own a perfect distribution of thrust load and without significant deformations. The two columns frame is particularly suitable for application that need a narrow Working area (bead area).
