This section provides overview, applications, and principles of press units. Also, please take a look at the list of 5 press unit manufacturers and their company rankings.
A press unit is a type of press machine that can control the speed and frequency of the presser, which was conventionally considered difficult.
The presser is driven by a CNC-controlled servo motor, and the presser pressure, processing speed, and position can be strictly specified.
Press unit can finish even complex workpieces uniformly without causing seizure defects.
In addition, since appropriate conditions can be set for each material, press unit have the advantage of being able to handle materials that have been difficult to process in the past.
Press units are gradually replacing conventional presses because they combine high machining accuracy with short machining times and can handle difficult materials.
Especially in the automotive industry, weight reduction is being promoted for body parts such as doors and hoods, using alloys such as aluminum and titanium, and carbon fiber reinforced plastics. All of these materials are difficult to process with conventional presses, and press units can process them with high quality and efficiency.
Press units are able to make precise settings during pressurization because they utilize servo motors.
A servo motor is a motor system that constantly monitors its own state (number of revolutions, torque, etc.) and can apply feedback to achieve a set value. This allows the press to be set to variable speeds and precise positioning at will.
Conventional presses only operate at a constant speed, which can be time consuming when processing materials that need to be pressurized slowly. However, servo motors can be set to slow down only when the press contacts the material and applies pressure, and then quickly return to the original position once the press has reached the lowest point. In this way, the press can significantly shorten the work time while maintaining processing accuracy.
Also, since press units are computer numerically controlled (CNC) presses, they can be easily linked to external equipment and programmed to perform even more complex operations.
