The flying cutoff serves to cut the endless tube, emerging out of the mill, into commercial    lengths. The Cold cutting process additionally provides for an almost burr free cut of tubes and profiles.

The flying cutoff is suitable for installation in any new or existing tube and profile manufacturing line and works automatically & independent from the tube mill’s control system.

The machine consists of a carriage, traveling on a base frame and guided by a linear motion system. The base frame and the carriage is of a very sturdy design and is made of fabricated steel. The carriage is fitted with the special backlash free gearbox for saw blade drive with incorporated saw blade shaft and a flange mounted AC motor. The complete saw blade drive is mounted on an inclined slide moving on another set of LM Guides operated by a servo motor via ball screw mechanism to enable an electronically controlled blade feed related to the progress of the cut.

The two pneumatically actuated tube clamping devices, with interchangeable clamping vices, are fitted on the carriage. The vices are surrounding the tube completely and are easily interchangeable as per tube size. The clamping is performed at an angle, providing for best results when clamping square & rectangular profiles.

The carriage travels on four slides of the linear motion system and is powered by an AC Servo motor via an inbuilt zero backlash planetary gearbox transmitting to a Timing belt & Pulley system working under pre-tension to facilitate an absolutely positive driving mechanism.

The movement of the carriage is controlled by a micro controller, which guarantees very close cutting tolerances. An incremental encoder records tube speed & length and submits it to the controller. The controller senses, monitors & controls carriage acceleration, speed, synchronization and cutting position.

In case of a power failure or failure of electrical controls, there are automatically adjusting hydraulic shock absorbers provided at both ends of the base frame. Also in such case, the blade, if in cutting position, immediately shoots back to its top position to save the blade against breakage due to a possible synchronization failure.
