Crankshaft grinding with the NUMERIKA GH 1500 corundum grinding machine

Grinding flanges and journals simply and precisely

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

The NUMERIKA GH1500 cylindrical grinding machine reliably produces thyssenkrupp‘s crankshafts. The user-friendly control system, a torsion-resistant machine bed, hydrostatic guides and grinding spindles with hydrostatic bearings ensure ideal corundum grinding results. The user-friendly control system offers the required input screens for grinding with corundum.

thyssenkrupp Forged Technologies operates 17 locations in 8 different countries and is part of the thyssenkrupp AG headquartered in Essen, Germany. In his 21 years at thyssenkrupp, Process Engineering Manager Jose Fernando Dias de Moraes has been actively involved in several grinding projects at the company‘s production sites worldwide. His experiences with ZEMA Zscelica Ltda during his career have been very positive and valuable.

You can always rely on the team from ZEMA and JUNKER – and that creates trust.

Dias de Moraes has been at the site in Danville, IL for four years now. Together with six other engineers, he 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. Also, 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 explains.
