Next generation NC joining systems from SI Instrumrnts exploit piezoelectric force monitoring

Features of the Kistler Staiger Mohilo NC joining module include:

• The joining module consists of a robust case with integral piezoelectric force sensor for measuring both compression and tension
• Its motor has an absolute encoder for exact positioning
• The compression or tensile forces acting on the sensor's piezoelectric measuring element generate a proportional electric charge converted by the integral charge amplifier into an analogue voltage signal
• The drive motor on the joining module is an electronically commutated AC servo type handled by a matching controller to ensure constant rotational and hence translational speed
• Standard functions of the joining module such as block pressing, position pressing and force feedback controlled pressing as well as intermediate positioning are supported
• The Kistler Staiger Mohilo NC joining module consists of the NC joining module, the evaluation system , and the servo controller IndraDrive
• A Profibus interface and an Ethernet port for outputting quality assurance data (I-P.M. or Q-DA format also possible) are standard on the joining module
  
• The positional and joining parameters can be edited directly using the system menus
