DownloadCrankshaft grinders – high-tech grinding technology, precision and reliability
PM 310 / 320 – Crankshaft grinders for the manufacturing of workpieces with a length of up to 1,250 / 1,750 mm (50 / 69 inch) and a weight of up to 150 / 200 kg (330 / 440 lb). The crankshaft grinders combines high-tech grinding technology with precision, reliability and ease of operation.
The modular system allows the configuration of a multitude of machine variants. The main and pin bearings can be machined in a single setup on the same crankshaft grinder or on two different crankshaft grinders, following the traditional concept, the decision depends on production requirements.
These crankshaft grinders were designed to produce crankshafts for passenger car and HGV engines.
