sheet-metal shearing is combined in the SAFAN M-Shear. The result is an extremely functional design that satis fies current and future requirements. Various possibilities for expansion, such as material-handling systems, are already incorporated in the design. This is not surprising, as the M of SAFAN M-Shear stands for multifunctional. At its core is the advanced hybrid drive for the cutting beam. This consists of a servo-electronic motor and a hydraulic pump, a combination that produces

M-Shear: Superior integration of hydraulics and electronics The robust hydraulic systems in the SAFAN M-Shear are controlled by modern electronics. This means that the regulatory mechanism has evolved from hydraulic to electronic technology. A successful
e-volution
that increases both your productivity and the quality of your products.
Low-noise and low-energy The servo-electronic motor powering the hybrid drive only runs when the cutting beam is in motion. This yields two advantages in a single stroke: you save a great deal of energy and the cutting cycle produces low noise levels. Since its introduction, the hybrid drive system has amply demonstrated its flexibility and reliability. In combination with the solid construction and the sophisticated, modular assembly, makes this SAFAN M-Shear a superior guillotine shear.

With the M-Shear, the blade cuts four ways. The standard equipment for the SAFAN M-Shear includes blades with four cutting edges, on both the top and bottom. Your shearing is done very economically because blade wear is spread over the blade’s entire length, thanks to the programmable starting position of the cutting beam. Cutting small blanks can also be done on the right side of the shear. Precision and automatic compensation

Ease of use with an E for ergonomic Maximum ease of operation is provided to you by the Safan Touch Screen control TS 200 which is standard on the Safan M-Shear. This TS 200 control makes it simple to work quickly and faultlessly. The settings are indicated by clear symbols on the TFT colour monitor. The control operates on Microsoft Windows速.

M-Shear: ‘safety first’ in accordance with the EN norm The standard safety features of the SAFAN M-Shear fully satisfy the European Machine Directive. The cutter beam drive is equipped with block hydraulics. All visible high-pressure lines are protected.
The shear has extensive guards on the back and sides.
Robust finger guards have been installed. For up to
