4.6. Setting the arm descent endpoint
only in ARG 520 DC CF-NC
Lower position end switch stops the arm descent. When cutting square or rectangular sections (I sections, U sections, etc.), it is
necessary that the cutting edges of the saw blade slide under the bearing surface of the vice along the whole cutting width. Only in
this way complete cut through the material can be secured. When cutting circular cross sections, it is sufficient if the cutting edges
reach under the bearing surface of the vice only to a half of the diameter of the workpiece. By adjusting the lower position end switch,
you can significantly reduce the overall cutting time, which leads to an overall increase in the production efficiency when cutting
circular cross-sections.
The resetting end switch resets the lower position of the arm with every cut. It is the bottom point for the calibration (see Chapter 4.1.
SETTING (CALIBRATION) THE ARM UPLIFT HEIGHT MEASUREMENT). This value is set by the manufacturer.
only in ARG 330 DC CF-NC
There is only one end switch and it corresponds to the measurement reset (see section 4.1. SETTING (CALIBRATION) THE ARM
UPLIFT HEIGHT MEASUREMENT). Adjustment is carried out via the lower position end switch placed on the column next to the
main motor.

4.7. Arm - Saw Blade Guidance
The arm of ARG 260 - 330 automat is made of robust casting from grey cast iron. The casting is hollow, which ensures extraordinary
stiffness when tensioning the saw blade. The arm of ARG 520 DC automat is a massive welded steel structure. The saw blade is
guided by two guide heads both behind and in front of the cut. The heads are fitted with eccentrically placed bearings and hardened
steel blade guides that allow easier rewinding of the saw blade as opposed to wheel guidance. The fixed guide block is placed on
a fixed guide bar and the movable guide block is placed on the movable bar. In ARG 260 - 330 automat, the moving guide block
moves towards the cut material by approx. 30-50 mm manually. In ARG 520 DC, the moving guide head moves along a linear
guidance and moves towards the cut material automatically, while the movement is tied to the moving jaw of the vice.
