CNC Controlled Machine for 0,5-3mm Sheet thickness (Steel)

Characteristics of the Luna MBC 8344 CNC rolls: CNC-control with the capacity to store 200 programs. Pre-bending and final bending in one cycle. All four rolls are driven. All axis are programmable. All movements are mechanical for highest accurracy. Can bend complicated elliptical shapes. Rolls mounted in inter-changeable cassette system. Adjustable crowning of the lower roll.

MBA (4126)

Manually operated bending rollers with centerless ground rolls dia. 25 to 45 mm, which are asymmetrically placed. The sides of the machine are produced from solid aluminium and anodised. The stand is made from steel chanel. The setting of the bottom and bending rolls is carried out by means of handwheels. The bending roll can also be set diagonally for cone bending. The top roll can easily be swung out for the removal of finished workpieces.

MBC 8268 CNC

The MBC 8268 rolls are designed to meet the requirements for longer CNC rolls for tight radius bending. The machine is designed with a welded steel frame and cast guides. The design with three rolls mounted independently in separate guides enables high productivity and easy adjustment of the rolls. These functions as prebending, bottom and bending rolls. The top roll is mounted above the middle roll e.g. a four-roll machine with symmetrically placed rolls. In order to control the bending result over the working length, the machine can be equipped with hydraulic crowning supports for the lower roll. This is carried out by three support blocks with four pressure bearings. The crowning is adjusted with a hand pump. All four rolls are driven in order to prevent scratches on easily damaged sheets from slipping rolls. The movement of the three lower rolls is carried out by lead screws. The four-roll system eliminates the need for any intermediate handling of the sheet between pre-bending and the final bending. This ensures high repetition accuracy as well as a rapid and rational production. When the bending is finished the lock clamp on the right hand side opens to allow removal of the pent part. This function can be eliminated in the program if not required.
