ROTO FLO machines are ideal for mass production of small gears/profiles and is
a lot more economical than gear hobbing. Workpieces are clamped between
centres and are profiled by means of synchronised rack tools, which rotate in
opposite directions. The material is displaced, and reshaped by the increasing
height of the profile in the rack tools. The profile and surface performance
is optimised in the calibrating zone of the tool. Profile run-out, which is
necessary when working with hobbing and shaping processes, is not required.
The machine stands out because of its extremely stable design. Tools have an
operating life of between 25,000 to 100,000 workpieces, also for helical gears.
