VT machining offers CNC Drilling for C101 Copper (UNS C10100 / OFE / Cu-OFE), typically supplied annealed or H02. Oxygen-free electronic copper with ≥101% IACS; for vacuum and hydrogen environments.
CNC Drilling Notes for C101 Copper
Drilling C101 Copper uses through-coolant carbide drills and peck cycles, because the chip tends to weld and the hole wall work-hardens if the drill dwells.
For estimating, a 100 × 100 × 10 mm block of C101 Copper weighs about 0.89 kg.
Starting Parameters for CNC Drilling C101 Copper
