Horizontal metal-cutting band saws allow for cutting of a wide range of different materials. Machines ARG 260 CF-NC, ARG 300 CF-
NC and ARG 330 CF-NC are articulated/swing NC automatic machines in which the arm moves along a curve while descending. By
contrast, the ARG 300 DCT CF-NC, ARG 330 DC CF-NC and ARG 520 DC CF-NC are 2-column NC automatic machines, in which is
the saw blade arm fitted on linear guidings and moves along a line. This ensures maximum rigidity of the entire system, ideal course
of the descent and thus also the accuracy and speed of the cut.
As the cutting tool, a welded saw blade is used, which is tensioned mechanically via a blade wheel. The saw blade is driven by an
impeller, which is driven by a single-speed motor via a worm-gear unit (conical face gearbox in the version of ARG 520 DC CF-NC
with optional accessories). In the machining zone, the saw blade guided through the saw blade guide heads. Outside the machining
zone the saw blade is protected by moving and fixed guards. The machine is equipped with a frequency converter that allows
a smooth regulation of the saw blade speed in the range of 15-90 m/min. Material clamping and the arm feed into the cut and back are
controlled hydraulically. The servo motor and the ball screw ensure high speed and maximum accuracy of material feeding.
Maximum length of a single feed is 500 mm, in ARG 520 DC CF-NC 600 mm. The control unit allows for programming of up to 60
programmes for quick setting of the feed length and number of pieces. Each program can be made active (the cut is performed) or
passive (the cut is not performed). Also, each programme can be annotated, e.g. by the drawing number. After programming and
pressing the only switch in the automatic mode, the whole cutting cycle is performed - moving of the material to the pre-set length by
the movable vice, workpiece clamping by the fixed vice, starting of the saw blade, the cut, stopping of the saw blade, lifting of the arm
to the upper position (adjustable) and opening od the fixed vice. The machine continues cutting according to number of set pieces,
and in case there are also other set programs, the machine will proceed with cutting of the other series. All functions can be controlled
separately. The machine can be controlled in fully automatic, semi-automatic or manual mode. The vice pressure control is included
in the basic version of the machine. NC machines are equipped with a removable container for the sawdust. In machines ARG 260
CF- NC, ARG 300 CF-NC, ARG 300 DCT CF-NC and ARG 330 CF-NC, it is possible to cut at an angle in the range of 90° - 45°.
Swinging of the arm is performed manually.
