SafanDarley is a global leader in the production of stand-alone machines and complete lines for cutting and processing cathodes. Cutting these rough and irregularly shaped nickel, copper or cobalt sheets of up to 30 mm in thickness requires a special technology. SafanDarley produced its first cathode shears as far back as 1986 and has since introduced many improvements and innovations which have made the latest generation of SafanDarley V-shears unparalleled in productivity and customer-specific efficiency.

• Almost unrestricted in terms of customisation
• Special hold downs to compensate for irregularities in the material
• Hydraulic cylinders are placed outside the cutting area (no oil leaks on the material)
• SafanDarley EasyControl with CNC programming of cutting programs
• Fully automatic setting of the cutting angle, blade gap and length of stroke
• CNC-controlled pusher OR CNC-controlled back stop
• Safety provisions in compliance with the European Machines Directive
• Optional pneumatic upward retention system
• Optional torsion-free cutting thanks to ATS

Precision cuts!

With its 2 mm capacity and 3100 mm cutting length the RAS SMARTcut combines all characteristics of a high performance, premium shear. The sheet support and sorting system leads the blanks to the backstop and sorts cut pieces to the front or the rear. When material thicknesses change, the blade clearance can be adjusted in seconds. The front and side beveled shear tables, the hardened squaring arm and the deep grip hollows simplify material handling for quick results. This is cutting efficiency at its best.

The SMARTcut comes with two machine models. The highest comfort level is offered by a best value, fast and dynamic CNC-backstop. Easy to operate and for lower budgets is the manual backstop, which can be positioned from the front. Both backstops offer a travel range of up to 750 mm. A foot lever determines, whether the part chute delivers the cut pieces to the front or the rear. This allows the operator to separate trim cuts or small parts from large parts without additional, later on sorting effort.

The innovative RAS SMARTcut uses the modern swing beam principle instead of the traditional guillotine concept. The upper blade penetrates the material above the lower blade and moves away from the lower blade after the cut is made. This results in twist free cutting of even small strips and gives you right-angled and burr-free!

Top technologies: PRIMEcut swing beam shear!

The innovative RAS uses the innovative swing beam technology instead of the traditional guillotine concept. The quick blade clearance adjustment guarantees clean and square cuts. The upper blade penetrates the material above the lower blade and delivers right-angled and burr-free parts. The tilting motion of the swing beam eliminates parts getting stuck between the lower blade and the backgauge. The extremely low rake angle of less than 1.0 degrees assures twist free cuts even at about 15 x material thickness! Special blades are ideal for mild steel as well as stainless steel applications.

Touch-Cut control

The Touch-Cut control positions the backstop to the programmed dimension and cuts the required number of pieces. The operator can program a single program line or can create entire cutting programs. Up to 50 programs with 20 lines each can be stored. The machine can be operated either in a single or continuous stroke mode. With the settings menu you can access the languages, the mm/inch selection and a screen-cleaning mode.

Precision cuts with LED cutting line illumination

The CNC backgauge positions the blank within the 750 mm stop depth. If the blanks need to be positioned below the shear blades using marks a bright LED cutting line illumination simplifies the work. A squaring arm with hardened and self-cleaning eccentric stops perfectly squares the blanks. Beveled shear tables with large grip space between the tables makes handling quick and easy. A plastic coated hold down offers mar free material clamping during the cut is made.

Configurable shear table

The PRIMEcut shear offers a variety of different shear tables even for extra large blanks. This allows a flexible and customized configuration of the shear table due to specific needs. With the moveable squaring arm and table extension the shear table support area can be enlarged up to 3 meter length.

Perfect sorting of cut parts

A sheet support and sorting system is already included in the standard machine configuration. The sheet support guides even the thinnest materials horizontally and accurately to the backstop. A foot lever position determines whether the parts chute delivers cut pieces to the front or the rear. Usually, the shear sorts the larger parts to the front, while smaller parts and trim cuts will be directed to the rear. The cut pieces will be delivered to a parts collector or a moveable stacking carriage.

Flexible safety concept

Protective fences and safety light beams together with the attractive machine design complete the PRIMEcut safety concept. They prevent access to the rear of the machine during the work process. Protection systems are available with fences/door for safe-guarded access from the right or left side, or with fences and safety light beams.
