Compact Electromechanical NC Joining Systems for Efficient Assembly

Kistler's new generation of electromechanical NC joining modules NCFH (such as Type 2151B…) offers a particularly compact and precise system for a wide variety of force displacement monitored press-fitting and joining tasks.

Unrivalled shortness and compactness even enable under-bench mounting. Despite an overall height of only 475 or 795 mm, these modules offer a stroke of 200 or 400 mm, which allows them to reach even deep end points, such as the position of bearings in half shell gearboxes. The high speed of up to 300 mm/s offers a quick return stroke and hence short machine cycle, even for a long idle stroke. Standard availability of both tension and compression forces leaves considerable machine design freedom. The force signal employed by the force-displacement monitoring system is used to control movement in highly specialized operations.

The force control system increases the application versatility of the electromechanical NC joining system. Spring elements, for example, can be loaded to specific values or their settlement controlled continuously. Two central lubrication connections for guide and bearing ensure very low-maintenance operation and the threaded spindle drive is permanently lubricated. As the active buckling compensation system eliminates the effect of bending of the customer's assembly, the positional accuracy is no longer influenced by the force. The standard holding brake allows the use of particularly heavy tools and prevents the ram dropping when the module is switched off.

This new electromechanical joining system vastly improves efficiency in assembly.
