“Quality Minded for the Future!”

In 2012, C&B Machinery developed three impressive grinding cells for General Motors, Linamar and Federal Mogul. The engineering of each grinder resulted in production advancements for non-coplanar connecting rods (step rods).

The DG-2H-RE model reciprocator, designed for General Motors’ Volt, was the first machine to simultaneously configure a coplanar connecting rod into a stepped rod. Impressively, the DG-2H-RE also has the ability to produce a completely finished part including the loading, unloading, part rinse, and blow off in 21.8 seconds (165 PPH). The process for General Motors required a crank reduction of 1.715 mm per face and a pin stock removal of 0.3mm. This same cell can be easily converted to grind coplanar connecting rod for the Cruz.

Linamar’s Flex cell was developed towards their lower volume non-coplanar connecting rod production process. C&B’s advanced swing arm technology provided a pin reduction of 4.9 mm.  A rough cut step grind (OP10) directly followed by a finish grind cycle was achieved in a single load. The Flex cell also provided a stock removal of 1.75 for the crank end in a cycle time of 39.6 seconds (66 PPH).

One of the greatest accomplishments of the year came with a non-coplanar reciprocator grinder designed for Federal-Mogul. The crank end stock removal requirement was 2.3 mm per face and pin end reduction of 0.3 mm per face. Not only did C&B Machinery provide a reciprocator meeting those specifications; but they did so with a floor cycle time of just 18 seconds (200 PPH).  The cycle time includes the loading and unloading process steps.

C&B continues to provide cutting edge turnkey and integrated product solutions. They successfully launched the newest version of their Vertical Micro Finishing Clamp Bore grinding cell.
