Tooling solutions for machining of Connecting rod

Connecting rod 

The connecting rod transfers the linear movement from the pistons to rotate the crankshaft.It is under tremendous stress from the reciprocating load and is stretched and compressed with every rotation., This load increases with the square as the engine speed increases. The big eye is nowadays normally cracked , versus the earlier method of parting off with a milling cutter. If the big eye is cracked, it may be pre-machined with a laser crack that puts high demand on the following boring process.

The manufacturing process of connecting rods has to be precise regarding key tolerances and at the same time cost-efficient.

Besides our extensive offer, Sandvik Coromant also hasve dedicated products and engineered solutions that fully support overtaking the challenges manufacturing these components presents.
