6.2.1 Cutting bridge frame
The cutting bridge frame is a steel Fe37 weldment ; it is machined to be assembled with other machine components.
The bridge was design and built to endure the cutting strength, keeping enough sturdiness.
The frame is mechanically machined and painted with anti-corrosion agents and with nitro paint.
The blade is completely protected where it does not work. Covering the wheels, there are two doors that can be opened to
change the blade. Two safety switches are mounted on these doors, so to stop the machine if the covers are not in position.
The blade rotates on the wheels, one of which is driven, and the other one is idler.
6.2.2 Guiding columns
The columns guide vertically the cutting bridge movement. They are made with chrome bars, hardened and grinded.
6.2.3 Columns connection
Made using a Fe52 steel square tube, the columns connection connects and makes the guiding columns sturdy. It is fastened
to the columns through two locknuts. The lifting cylinder is fastened to the center of the connection tube.
