Grinding machine operates at high speed similarly other machine tools but the difference in the operation. The grinding machine used for finishing only after the machining done by some other machine tools. We can say that the function of the grinding machine comes into play after the machining of a work piece by turning or milling machines.
The chromium in the steel reacts with oxygen to form a thin layer of chromium oxide on the surface of the steel. This process is called passivation.. This process seals the surface of the steel and protects it from further rusting so that it stays bright and shiny. The passivated layer is self-healing, too.

Dec 08, 2020· Corrosion is a natural, oxidation process. When you prepare a metal surface for welding, it becomes exposed to a variety of atmospheric elements like oxygen and humidity, which creates the perfect condition for rusting. This is why it is important to clean and polish your welding projects before and after the welding job.
The electrochemical process will not only remove imperfections on the surface after welding but it will also restore the oxide layer that returns stainless steel back to its normal passive state. Unlike grinding, this cleaning method will successfully remove all dirt and discoloration from the welds.
GREAT timing and question - thanks! So I was just asked today to repair a metal bracket for some family that is about 3/4" thick. The weld is going to be a butt weld - I was planning on grinding a bevel on all "four" edges - top and bottom side and then using my Thunderbolt 225 XL to run a root pass of 6010 in each side then maybe 7018 pass over the top and grind it down (now with a flap disk
