Brankamp X1 and X3 in-process monitoring systems for cold- and hot-forming, thread-rolling, and stamping operations provide real-time monitoring of machine parameters to identify manufacturing faults as well as part or tool variations. Process-integrated monitoring can detect quality defects such as cracks in components, broken tool elements, turned, or mis-introduced parts.

Sensors, placed in the right positions, convert energy into electrical signals that monitor tool and machine performance related to the forces applied. The systems learn the normal limits of the process, then the control unit observes the signals of each cycle and compares it with the stored curve. When the signal moves outside of the envelope curve, the formed part is sorted out or the machine is stopped.

The X1 and X3 systems provide eight channels for sensor signals and four others as zoom channels for detailed monitoring of specific, sensitive process areas.

Indexable punch broaches, holders

Indexable punch broaches and holders machine shapes in workpieces where rotary broaching may not be feasible – such as greater depth of operation, tough materials, tooth height, chip evacuation challenges, and applications that require orientation.

Punch broaches are available to machine keyways, hexagons, Torx-style sixlobes, serrations, splines, and squares. In combination with the range of punch broach holders, users can expect high repeatability on lathes, milling machines, and presses.

The indexable punch broach holders use partial form broach tools and index either the tool or the workpiece, greatly reducing cutting pressure. This method of broaching benefits applications requiring no witness (pre-drill) marks, with excessive material removal, or when timing the form to a feature on the part is required.

Holders feature a rigid design with standard shank diameters ranging from 0.625" to 1.250". Metric shanks are also available.

Self-clinching, free-running locknuts

PEM S-RT self-clinching free-running locknuts feature a modified thread for easier tightening of mating screws and vibration-resistant locking performance in thin metal assemblies. The modified thread formation allows mating screws to spin freely during attachment until clamp load is induced during the screw-tightening process. The applied clamp load then engages the locknut’s vibration-resistant locking feature, which locks the screw in place.

PEM S-RT self-clinching locknuts install into aluminum or steel sheets as thin as 0.030" (0.8mm) and become permanent parts of an assembly. Upon installation using a Pemserter or other standard press, the back side and assembly side of the host metal sheet will be flush or sub-flush for screw insertion.
