Why is stainless steel so difficult to surface grind?

stainless steel surface grinding

Typically when faced with surface grinding stainless steel, many companies turn it away. It is the unwanted material of a surface grinding operation and rightfully so.

Stainless steel’s thermal conductivity is very low compared to other steels, meaning the heat is going to stay on the surface of the workpiece for longer periods of time. The downside of this is that, if not accounted for properly, the workpiece could burn or warp, causing the whole piece to potentially be scrapped. Neither customer or grinding operations want to replace workpieces, taking up time and funds plus the time to grind the new piece.

The best solution to stainless steel surface grinding is as simple as taking your time. While it can be time-consuming, our operators are sure to dress the wheel more often when taking on stainless steel jobs, along with flipping the piece to avoid burning or warping the one side, and decreasing the feed rate to control the temperature.
