Intensive wear: previous attempts to reduce wear uneffective, because of the constantly changing torque angle

FriCSo’s polymer lapping adds an oil-retaining organic nano-layer, hardens the metal surface, and produces an extremely flat, smooth superfinished surface. FriCSo polymer lapping is performed in-line on the current through-feed superfinishing machines. No capital expense and no change in production throughput are required.

• 25% reduction of coefficient of friction
• Longer service life where other solutions failed
