Crankshaft grinder PM 2 for the machining of crankshafts up to 700 mm long

The crankshaft grinder PM 2 is the best grinding machine for crankshafts used in passenger car and motorcycle engines (2-, 3- and 4-cylinder).

The crankshaft grinder PM 2 is equipped with a grinding head that features a 30 kW motor spindle, a work head with direct drive, a linear motor for the X-axis and a sturdy tailstock. This gives the PM 2 all the necessary features of a modern, efficient crankshaft grinder.

Crankshaft grinder PM 2 – Inexpensive component manufacture

PM 2 – crankshaft grinder is for the machining of crankshafts up to 700 mm (27.6 inch) long and 30 kg (66 lb) in weight. Thecrankshaft grinder combines hi-tech grinding technology with precision, efficiency, reliability, and ease of operation.

The crankshaft grinder PM 2 is a hook-up-and-install machine, with electrical cabinet and energy container located within the machine enclosure. The possibility to connect the crankshaft grinder to an automated loading system or an external grinding dust extractor is ensured.

Pin chasing will be just as much a standard operation on the crankshaft grinder PM 2 as the use of CBN grinding wheels. The machining process allows for either oil or emulsion to be used as cutting fluids. With the pin chasing process pin bearings and main bearings can be ground in one set-up.
