4-roller plate bending machine 8344 series

electricCNC

Suitable for small to medium production as well as complex shapes, the 8344 CNC can bend profiles with variable radii and sections. The design with three lower bending rolls, mounted in a cassette, which is swivelling and adjustable in height, enables bending of very complex profiles in one single operation. The three rolls of the cassette are used as prebending roll, bottom roll and final bending roll. The cassette system also allows exchange of the rolls to other dimensions (applies to 70, 80 and 90 mm). The special design of the machine and the location of the four rolls eliminate all intermediate handling of the sheet between the prebending and the final bending. This simplified working method also means that the storage space around the machine can be reduced, a higher repetition accuracy is achieved as well as a higher productivity. The adjustment of the cassette into the programmed position is carried out by means of ball screws. When bending is finished the lock clamp on the right hand side opens for the removal of the profile, if the profile is not closed, this function can be eliminated in the control program. As standard the machine is delivered with hardened and ground rolls, motor 400V 3-phase and 24V control voltage. •CNC-control with the capacity to store 200 programs in internal memory and nearly unlimited by attaching an external USB flash drive •Pre-bending and final bending in one cycle •All four rolls are driven •Crowned rolls •Programmable axis •Designed for highest accuracy •Rolls mounted in changeable cassette system •Openable locking arm
