At the EMO in Milan, MAC is also going to present the coldforming technology. With the modern, energy-efficient and hydraulic-free high-performance coldforming machines of the XK6 and XK8 series MAG stands for robust and high-precision manufacturing processes in the world of splines.

An absolute novelty at the EMO is the Advanced Involute Profile Technology (AIPT). This new tool technology promises even better gearing quality and tread element loading, according to MAG. Until now, in coldforming was a process-related indentation in the base of the gearing could hardly be avoided. This often resulted in uncertainty in the course of the customer’s component measurement, concerning optimal state of the gearing. “In order to reduce a process-related undercut, i. e. an indentation of the involute, we have developed this new technology,” says Jürgen Schmid, Head of MAG’s coldforming Business Unit.

AIPT involves both a software and tool development. By means of a special CAD software unscrewing the cutter tooth with an undercut is simulated. After that, the gear cutting tools are designed accordingly. “With our new technology, we can reduce the undercut significantly, right up to eliminating this deviation,” says Jürgen Schmid. This directly affects the component because the longer involute can transfer more forces and the spline shaft is more resilient. Measurements show an increase of the involute’s active contact ratio up to 20 percent. In addition, the risk of resulting fretting corrosion on gearing base is lower.
