The movement of both the spindle-holding carriage and the beam are in an oil bath, always precise, rapid and well protected. Once the beam has reached the correct position, it is blocked laterally on the bridges by means of a double oil-pressure device.
The two bridges move on sliding blocks with play adjustment along the guides, which are housed inside the columns, well protected by labyrinth seals. The spindle-holding carriage is moved horizontally by an electric motor controlled by an inverter.
The 550 mm ø horizontal blade spindle is mounted vertically on one side of the carriage and it can be adjusted in height by a rack and pinion assembly powered by a reducer with invertercontrolled A/C motor. The unit is equipped with a mechanism for the automatic compass movement of the blade. The rectified and dynamically balanced spindle shaft guarantees an exceptional precise rotation.
