While Metaldyne delivers innovative products, our customers also look to us to deliver innovative processes to solve specific challenges. Our patented DynaTurn^TM Process addressed and solved a very real need - hub distortion caused by bolt installation. As shown on the illustrations below, the distortion influences were significant and were affecting brake performance.

In addition, customers complained about noise, vibration and harshness - key quality considerations for any automaker.

After analyzing the problem, identifying its source and considering alternatives the Metaldyne team developed a patented solution - a process that finished turned surfaces and eliminated component stack up and reduced brake rotor runout.

DynaTurn^TM Defined
Modules featuring our unique DynaTurn^TM process provide distinct performance benefits. Corner lateral runout was significantly reduced and brake performance made smoother. Specifically, this can be measured with exact numbers, depending on the process utilized:

• DynaTurn^TM I - lateral runout of 10 microns or less on hub face (roto-mounting surface) after bolt installation and assembly to bearing and knuckle; and robust braking due to low assembled runout
  
  
• DynaTurn^TM II - lateral runout of 25 microns or less on rotor brake surface after assembly to wheel-end module; and minimized brake judder and noise
  
  

Best of all, DynaTurn^TM is a process that addresses major NVH concerns. It minimizes the root causes of deteriorating brake performance -- disc thickness variation (DTV) and corner Lateral runout (LRO). At the same time, it minimizes caliper drag and optimizes wheel interface design. All those technical benefits lead to one overall performance benefit noticeable to drivers - less brake noise and vibration and a smoother driving experience. Added benefits for OEMs include improved brake longevity and reduced brake warranty expenses.
