CRANKSHAFT MACHINING

Within our machine park, we have machines manufactured by Berco and AZ, with which we process crankshafts up to 3.5 m in working length.

What is a crankshaft and what is its role?

Crankshaft is a rotating shaft that converts the rectilinear movement of the pistons into a circular motion and transmits their power to the transmission system (gearbox). The pistons are connected to the crankshaft via a connecting rod, and the crankshaft itself is installed in the engine block.

How does a hazard occur and how is it resolved?

Since the crankshaft represents the “backbone” of an engine, any kind of hazard may lead to serious issues to the engine. Crankshaft failures are mainly caused by poor engine lubrication, but also by operating at very high engine temperatures. Depending on the degree of damage, the crankshaft can be processed to an oversize. This specifically means that the damaged layer of the crankshaft sleeves is removed through the grinding process, and that same layer is replaced by the installation of adequate reinforced bearings.

Available operations are:

  • Rod bearing journals grinding
  • Main bearing journals grinding
  • Polishing
  • Magnetic flux testing
