Electromagnetic Crack Control

We have been realizing the electromagnetic crack detection process by high-tech American Magnaflux Mag50 machines. This machine is a 5000 power amp that is able to control the x and y direction of cranks. In addition, It is able to detect te unseen cracks of surface untill 2mm . This process allows the machine to create a temporary magnetic field of crankcshaft at high doses of electricity. A piece of liquid is sprayed onto magnetic field after creating magneting particles. After spraying the liquid on the cracks, it is clealy seeable under the ultraviolet light. Crankshaft Grinding : Crankshaft is forged or poured alloy steel generally in one piece. Journal surfaces are machined to increase its strenght in order to reduce wear up to a certain hardened and precision depth againist the shocks. Crank shafts are usualy found wear stratches, burning, rolling, cracks by such as bending or lifting way. Our company has been machining the cranks with the Italian Zanrosso MITO 280 series. We are able to machine each type of spot or centerles cranks at maximum capacity of 2.5 mm length.
