In-Place Crankshaft Machining and Grinding

In-Place Crankshaft Machining

Goltens has long been the leader in in-situ crankshaft machining and crankshaft grinding for repairing large diameter crankshaft and journal surfaces. As the first company in the world to complete in-situ crankshaft grinding in the early 1950s, Goltens’ patents on its in-situ crankshaft grinding tooling revolutionized the industry with massive reductions in downtime for owners coping with crankshaft failures and damaged journals.

Precision Machining for Crankshafts

Precision is paramount in crankshaft machining. The crankshaft is a vital engine component, converting the pistons’ reciprocating motion into rotational motion. Any inaccuracies in the machining process, whether it’s crankshaft grinding or polishing with a crank polisher, can significantly impact engine performance and reliability.

Through constant and focused R&D and field trial, Goltens has developed the most cutting-edge in-situ crankshaft machining tooling in the industry. On larger diesel crankshafts and damaged journals, this allows our highly skilled technicians to perform large scale jobs in a fraction of the time of traditional grinding, oftentimes with a single cut, fillet to fillet, with the highest tolerances.  Goltens’ machining tooling can be applied to any large journal repair.

Goltens’ experience repairing damaged crankshafts extends far beyond the grinding and machining of crankshafts. Goltens has a great deal of experience repairing bent and twisted crankshafts In-Situ as well as the expert application of our in-situ crankshaft annealing process to remove hardness and salvage otherwise condemned crankshafts.

Quality control is a top priority in our machining process. We implement rigorous measures to monitor and inspect each stage, from initial setup to final inspection. Our quality control procedures include dimensional checks, surface finish analysis, and material testing to ensure every crankshaft meets our stringent standards.

Goltens’ brand has always been synonymous with the repair of diesel crankshafts however, every year Goltens applies this precision machining technology to problems in the marine, industrial, stationary power and offshore sectors. Goltens is routinely called upon to repair damaged journals on any and all manner of rotating equipment including compressors, steam turbine rotors, worn turbine collector rings, hydro turbine journals and a myriad more applications.
