Electromechanical Joining Modules facilitate press-fitting processes.

Press Release Summary:

Used in standardized joining and press-fitting processes with force displacement monitoring, NC joining module NCFB Type 2160A integrates piezoelectric force sensor into case and offers choice of predefined 25 and 50 kN measuring ranges. Deep end points can be reached with 400 mm stroke, and speeds up to 150 mm/s shorten machine cycle. Use of absolute encoder eliminates need for reference point determination, while firmware aids force displacement evaluation.

New Electromechanical NC Joining Module NCFB - a Low-Cost Alternative

Kistler's electromechanical joining modules facilitate automation of force-displacement monitored joining and press-fitting processes. The new NC joining module NCFB Type 2160A... has been specially designed for standard joining processes and is an enhancement of the existing product range. With its cost-optimized design, it offers a more favorable price/performance ratio. The piezoelectric force sensor integrated into the robust case offers a choice of two predefined measuring ranges, 50 kN and 25 kN, for precision force measurement.

Even deep end points such as the position of bearings in half-shell gear boxes can be easily reached with a 400 mm stroke. The speed of up to 150 mm/s offers a quick return stroke and hence a short machine cycle, even for a long idle stroke. The use of the absolute encoder, which is part of the standard equipment on all Kistler NC joining modules, eliminates the need for reference point determination even during operation.

The NC Compact Firmware (2159A...), which is integrated into the servo controller, is perfect for simple force displacement evaluation and documentation of standard joining tasks with the NC joining module NCFB. With extremely low investment and mounting costs, it facilitates integration into the customer's existing control environment.

The Operating Panel (2158A) is used for parameterization and visualization of a standard joining process and for data backup. It is not required for ongoing operation. It has 16 different programs for optimum flexibility in the joining process. These contain functions such as measuring range switchover, fast shutdown, force control, active deflection compensation which eliminates the effect of bending of the customer's assembly, intermediate positioning and evaluations with up to three analysis windows.

The force-displacement monitoring unit DMF-P A300 NCF Type 4734A... can be used as an alternative to the NC Compact Firmware. With its wide range of analysis windows, it can evaluate the force displacement curves of virtually any application. Moreover, it allows comprehensive documentation of curve developments and the associated target and actual values.

The new Kistler electromechanical NC joining module NCFB Type 2160A... for low-cost automation of standardized joining and press-fitting processes with force displacement monitoring.
