Tooling solutions for machining connecting rods
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. These days, the big eye is 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 has dedicated products and Engineered solutions that fully support overtaking the challenges that manufacturing these components presents.
Tooling solutions that support manufacturing connecting rods:
