Cold Rolling Machine The function of the machine lies in the technology of cold forming - rolling of cylindrical, conical and transition radius surfaces of shaft components, e.g. vehicle axles. Among other things, this function predetermines the area of ??application of the machine for specialized production of parts using surface strengthening technology, always perpendicular to the surface of the rolling tool to the material surface by means of the B-axis tilting mechanism controlled by the CNC system. he locking of the rolling heads in a given position is ensured by a drive with self-locking worm gearboxes. The rolling equipment is located on a longitudinal support. The slide moves along the machine bed in the longitudinal direction by means of a CNC- controlled Z axis. The movement in the X-axis is realized hydraulically by two quill of rolling heads placed against each other, into which the rolling tools themselves are clamped. Continuous pressure changes on the rolling tools can be changed in the program during the work cycle. The system enables indirect independent measurement of rolling force, recording and archiving of rolling process data. equipted with : - CNC control Siemens Sinumerik model 840D - Tailstock - Hydraulic Unit - Lubrication Range of multi-roller power: 1-50kN - Max. power of multi-roller with using of tilting B-axes (B = ± 35°: 20kN - Max. power of multi-roller without using of tilting B-axes (B = 0°): 50kN Axis B: - Ratio of worm-gear unit: 1:40 - Ratio of spur gearing of tilting mechanism: 1:12

Ø 16 x 200 mm long, with prism conveyor belt and lifting station for 2 shafts (blank and finished part), as well as workpiece positioning control. * Originally, external gears were formed on the machine using pinion cages (no. of teeth = 25), Ø approx. 32 mm x 14 mm long, workpiece Ø approx. 80 x 80 mm long. * Various accessories: * Separate switch cabinet. * Separate hydraulic unit, 900 l. * Coolant device in the machine. * Control panel with malfunction message in plaintext, etc. Roto Flo machines are ideal for mass production of smaller gears/profiles. The coldforming process is a lot faster and more economical than other chip removing methods. Workpieces are clamped between 2 live centres and 2 synchronous opposed directional coldforming racks simultaneously engage the workpart and start rotation. During rotation, the profile is formed successively within one stroke. In the calibrating zone, the profiling and surfacing performance of the tool are optimised. Profiles do not require a run-out. The coldforming process requires a rigid and heavy duty construction of the machine, which ensures the required precision over the years. Between 25,000 and 100,000 working cycles can be performed with one set of racks, also for serrations. Condition : Very good. Machine can be inspected under power. Delivery : Ex stock, as inspected. Payment : Net, after conclusion of contract. Thank you for your interest. We always have a good selection of gear machines available. Please let us know what you need.
