Combined roller – rotary and flat dies Ingramatic, part of the Sacma Group, has introduced a new range of combined rollers where the implementation of the rotary rolling unit extends the capacity of the flat die rolling machine. The unit is a rotary thread rolling station inspired by the established Ingramatic GR machines. The modular unit allows complex parts to be run in one shot without refeeding the part. The RP620-RR12 is claimed to be the only machine of its kind, with advanced technologies, a heavy-duty frame, servomotor starter units and motorised die match adjustment. The operator can set the machine completely using the electronic handwheel.
