Renovation of studs with round threads

Round threads are used where extreme loads are expected and where there are demanding corrosion conditions and high pollution. This was also the case for the last 60 years, where these threads were used on locomotive pins. Manufacturing new 12 pins according to the original ones would have been expensive, but after removing the corrosion using the ROD500 pulse laser , it turned out that the original surface was not significantly damaged and that there was no problem in renovating and reusing them.www.lsrservices.cz
