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.
