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.
