Servo press module with wireless telemetry for clean room use

26 June 2012

Suitability for use in cleanrooms to ISO standard and wireless telemetry of the force signal are just two of the attributes of the new Kistler Type 2157B NCFT electromechanical, servo press module.  These new features make the new module particularly suitable for use in processes with small test and joining forces, such as sensitive press-fit operations and test routines in the medical and precision product sectors.

The compact mechanism, integral piezoelectric force monitoring in the ram and two predefined measuring ranges from 0.05 kN to 1.5 kN make the new modules ideal for use in assembly and joining processes monitored by force-vs-displacement.  Advantages include easy selection of the ideal measuring range, a high overload factor and modest user spare parts inventory. Complex drive profiles with a maximum speed of 400 mm/s and displacement repeatability of 0.002mm can be achieved.

The new NC servo press module provides ultra-high precision measurement of extremely small forces directly on the tool holder under actual process conditions, without the need to mount a sensor on the ram. This eliminates any possibility of the measurement signal being impaired by dynamic characteristics of masses or moving cables.
 
Many medical consumables are required to be manufactured under cleanroom conditions. The NC joining module Type 2157B meets the stringent, cleanroom production environment requirements defined by ISO 14644-1 Class 8 as standard and Class 7 conditions can be met with minor adaptation.

The new NCFT augments the range of NC servo press systems from Kistler. Five series now provide seamless coverage of measuring ranges from 0.05 to 600kN. They are available not only as a system subassembly but also as complete manual workstations for development, prototyping or small-batch production.
