Special machine designed for the deep rolling of shaft parts

The special ROLLER 2800 CNC machine is the skeleton of the machine and derived from the standard MT 70/3000 CNC lathe machine. The function is based on cold forming technology – the rolling of cylindrical, conical and transition radius areas of the shaft parts, i.e. vehicle axles. This function pre-determines the area of use for the specialized production of parts with the use of technology for surface compaction. 

The form rolling equipment is located on the longitudinal support. The support moves by means of CNC controlled axis Z on the bed of the machine in a longitudinal direction. The movement in axis X is performed hydraulically by two opposite retractable tailstock sleeves of the rolling heads into which the rolling tools are clamped. The force of the rolling can be adjusted hydraulically.  

The arresting of the turning of the rolling heads in the respective position is ensured by the drive with self-locking worm gears.
