Kistler expands assembly system with new joining modules

Kistler Instruments (www.kistler.com) is expanding its well established electromechanical, press fit joining system with the addition of two new compact NCFH modules with 10 kN and 15 kN nominal joining force to replace the existing 10 kN module. The use of integral piezoelectric force sensors allows a range of measuring range combinations from 1 kN to 15 kN from just two modules.

The new modules are mechanically and electrically compatible with the earlier 10 kN module but are more versatile due to the additional measuring ranges. Although only 475 mm long, the NCFH modules have a stroke of 200 mm allowing operation deep inside enclosures such as gearbox casings. The high stroke speed of 300 mm/sec and quick return stroke ensures a short machine cycle. Both tensile and compression types are standard allowing maximum machine design flexibility and the standard holding brake holds even heavy tooling safely when electric power is removed.

The Firmware, integrated into the servo controller, is designed for force displacement evaluation and documentation of the joining process. The system provides force control and active deflection compensation making positional accuracy independent of force by eliminating the effects of the assembly bending under load.

Compact size, high precision and low maintenance operation make the Kistler NC electromechanical joining system ideal for all types of assembly processes where reliability, low cost of ownership and machine design flexibility are essential.
