NC Joining Systems Exploit Piezoelectric Force Monitoring

Electromechanical NC joining systems are taking over from the familiar hydraulic presses and conventional joining modules. In addition to environmental, energy, space, installation and maintenance benefits, it is primarily manufacturing criteria that sway the system designer towards an electromechanical system. These include flexibility, exact positioning, extremely high repeatability and accurately defined joining forces.

Kistler's new generation of electromechanical NC joining modules NCFH Type 2151B… offers a particularly compact, high-precision system for a wide variety of force displacement monitored press-fitting and joining tasks.

The integration of piezoelectric force measurement allows two types of modules (a small one for up to 10 kN and a large one for up to 60 kN) to cover the range of forces previously requiring seven. This very impressive interchangeability for the variety of conditions encountered with a given machine design is made possible by the switchable measuring range of the integral force sensor. This sector is a good example of where the advantages of piezoelectric measurement (generous over-load protection combined with consistent accuracy over wide measuring range) really come into their own, and how Kistler is setting new standards in joining technology.
