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.

Internal grinding is the primary process for the precision finishing of internal surfaces or bores. The bores may be simple cylindrical surfaces or may be surfaces requiring the generation of complex and exact profiles for applications such as bearing and CV joint races or fuel injection seats. Most precision internal grinding operations require the capability …

With the pipe rotating, the grinder will grind the weld down smoothly to the inner wall of the pipe. The oil drilling industry uses long continuous pipe to reach the depths of oil cavities. Short pipes are welded together to achieve the proper length required. For good strength, the welds are large and protrude through the inside pipe wall.
