Crankshaft Grinding Flanges and Journals



The thyssenkrupp Crankshaft Company in Danville, IL, uses the NUMERIKA GH1500 machine from ZEMA to grind its crankshafts. The external grinding machine works in a three-shift operation seven days a week, grinding ?ange and post end on heavy-duty crankshafts.

The NUMERIKA GH1500 cylindrical grinding machine features a user-friendly control system, a torsion-resistant machine bed, hydrostatic guides and grinding spindles with hydrostatic bearings. The control system offers the required input screens for grinding with corundum.

Process Engineering Manager Jose Fernando Dias de Moraes, along with six other engineers, oversees four production lines. The NUMERIKA GH1500 grinds crankshafts in three-shift operation seven days a week. The line, which mainly produces crankshafts for heavy-duty trucks and construction machinery from around the world, will expand with an additional NUMERIKA GH1500 by the end of this year.

"We have replaced a machine from the production line with the NUMERIKA, as the machine previously used was no longer reliable enough. The NUMERIKA works with precision and is easy to operate. We had already carried out a few projects together at other thyssenkrupp sites. The price and service are spot on. You can always rely on the team from ZEMA and JUNKER-and that creates trust," he said.
