Flexibility for Crank Finishing

AD&P Magazine

As a supplier of crankshafts to John Deere, Detroit Diesel, and Caterpillar; Krupp Gerlach (Dansville, IL) is microfinishing (superfinish) its parts with a new machine from IMPCO Machine Tools (Lansing, Michigan USA), the Worldflex. It is using it to achieve circular geometry and surface finish on all main and pin journals at a rate of as many as 20 cranks per hour (depending on size).

In operation, parts (it can also handle camshafts) are located between a headstock and tailstock mounted on a servo-driven ball screw slide that can position the part anywhere along the travel axis so as to present the bearing journals to the microfinishing (superfinish) tooling. The tooling is mounted on arms that are attached to slides, as well. This results in an ability to accommodate part size variations more quickly than is possible with microfinishing (superfinish) machines with fixed-position tooling. The amount of microfinishing (superfinish) performed is predicated on the amount of tooling applied to the workpieces.
