Friction screw presses
Screw presses are machines designed for forging, calibrating and straightening. Friction screw presses are forming machines in which the motion in the screw mechanism is caused by a friction gear: spur, disc, cone, roller or other.
This machine is equipped with a flywheel that turns the screws clockwise or counterclockwise to allow the slide to lower or raise. In this case, the transmission of motion from the electric motor to the flywheel is through friction created on a leather belt. Friction screw presses do not allow direct control of the motor and flywheel, but they have the significant advantage of saving energy. The average energy consumption for this type of press is about 40kWh.
