According to Kistler, numerically-controlled (NC) electromechanical joining systems are taking over from hydraulic presses and conventional joining modules.

In addition to environmental, energy, space, installation and maintenance benefits, it is primarily manufacturing criteria that sway system designers towards electromechanical systems. These include flexibility, exact positioning, extremely high repeatability and accurately defined joining forces.

Kistler's new generation of electromechanical NC joining modules, known as the 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 enables two types of module (a small one for up to 10kN and a large one for up to 60kN) to cover the range of forces previously requiring seven.

This 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 overload protection combined with consistent accuracy over wide measuring range) really come into their own.
