In-feed precision centerless grinding (or "plunge grinding") is used to accurately grind parts with more complex shapes, such as minimally invasive guide wires that can transition over a length of 2 meters from a starting diameter of 0.016″ (0.4 mm) to a distal tip diameter as small as 0.002″ (0.05 mm).

Internal grinding on a lathe. 03-15-2023, 04:17 PM. I've had several sets of small slitting saws for a number of years, but never used them. I did not have an arbor. So I made 2 of them, one for 6 mm bore and the other - for 1/4" bore. All is good, but 5 saws had an undersized bore, about 4-5 thou short of the standard size.
