Kistler Instruments is expanding its electromechanical press fit joining system with the addition of two compact NCFH modules with 10kN and 15kN nominal joining force.

The use of integral piezoelectric force sensors allows a range of measuring range combinations from 1kN to 15kN from just two modules.

The modules are mechanically and electrically compatible with the earlier 10kN module, but are more versatile due to the additional measuring ranges.

Although only 475mm long, the NCFH modules have a stroke of 200mm allowing operation deep inside enclosures such as gearbox casings.

The high stroke speed of 300mm/s 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 suitable for all types of assembly processes where reliability, low cost of ownership and machine design flexibility are required.
