Most flat surfaces on metal engine and transmission parts are generated using milling or broaching. When the part tolerances and surface finish requirements are more exact than can be repeatability produced with these processes, parts are ground.

Ford developed and patented a process that combines the milling and grinding of parts into a single processing step. The resultant quality is that of a ground part with processing times and costs similar to parts that have been milled. Ford has licensed a machine tool builder that is capable of supplying this equipment

The invention offered is best suited for transfer machines. It will simultaneously mill and grind a metallic flat surface in a single station with concentric milling and grinding spindles. Separate motors drive each spindle. This technology is designed for finish cut applications. It can be used on all aluminum and cast iron parts cut with water-soluble coolant. The technology is available today and has been in full production at the Ford Essex Engine plant since 1997.

Benefits Summary

Precision Surface Machining provides higher quality parts including improved height and surface finish characteristics and flatness. Precision Surface Machining eliminates post process grinding operation that reduces capital, labor, and material handling cost. Tooling cost is significantly reduced due to the optimization of both milling and grinding process. Additionally, Precision Surface Machining enables different part-to-part sealing technologies for increased customer satisfaction.
