Nelson Precision Drilling has centerless grinding capacity of .050” to 4” in diameter, up to 12’ in length and tolerances to .0001”. We regularly; purchase material, drill / hone the inside diameter, turn the outside diameter concentric to the inside diameter and centerless grind the OD to final size. These capabilities allow us to reduce the lead time and logistics costs for many of our aerospace customers by delivering them a semi-finished part.
