Hard turning, on the other hand, has geometric limitations, as is the case with long and thin components. Wide surfaces can be finished effectively, often with a single plunge grind operation. In addition, with grinding a turnfree surface finish is achieved which is often mandated on sealing diameters.

Replacing a traditional process with grinding depends more on how the part and wheel contact each other than on geometry. Similar to the slotting case, another example uses wheel technology, replacing the turning operation with grinding. Newer nickel alloys used in aerospace can be even more difficult to machine than legacy materials such as IN718.

· If you have enough coming off that you can finish turn it, you could get the hard chrome off first by grinding it off with a hand grinder. Finish turn it once the chrome is gone into grainy bits. If you just turn it, you might upset the adhesion near the end of the turned area and get peeling. I would suggest some grinding first.
