Cylindrical toothing

Cylindrical toothing with hob

The cylindrical toothing with hob is used for the manufacture of grooved profiles and external teeth with straight and helicoidal teeth. Gear hobbing machines cut by envelope, through a generation motion similar to that between two meshing elements, in which one is represented in this case by the tool called "creator". The rotation and/or translation speed of the elements involved must be set appropriately in order to obtain the correct transmission ratio between the tool and the wheel to be cut.
DEMM is equipped with gear hobbing machines with manual and automatic loading.

Cylindrical toothing with slotting machine

The cylindrical toothing with slotting is used for the manufacture of grooved profiles and teeth, both external and internal, with straight and helical teeth. These machines cut by envelope through a generation motion similar to that between two meshing elements, in which one is represented in this case by the tool called the slotter. The rotation and / or translation speed of the elements involved must be set appropriately so as to obtain the correct transmission ratio between the tool and the wheel to be cut. Unlike broaching, the toothing with slotting machine can also be carried out in pieces where the tool cannot completely escape, as there is the possibility of stopping this tool at a predetermined depth.
DEMM is equipped with gear shapers for crowns, shafts, gears in general, both straight and helical, with manual and automatic loading.
