VT machining offers CNC Milling for C102 Copper (UNS C10200 / OF / Cu-OF), typically supplied annealed or H02. Oxygen-free copper, slightly lower purity than C101.
CNC Milling Notes for C102 Copper
We use high-efficiency toolpaths with constant engagement on C102 Copper to keep cutting temperature and tool wear under control.
For estimating, a 100 × 100 × 10 mm block of C102 Copper weighs about 0.89 kg.
Starting Parameters for CNC Milling C102 Copper
| Cutting speed (carbide) | 130-255 m/min |
|---|---|

What is CNC Milling C102 Copper and how is it done?
CNC Milling C102 Copper refers to multi-axis milling cutters remove material to produce prismatic features, pockets, slots and contoured 3D surfaces. Applied to C102 Copper — excellent electrical and thermal conductivity — VT machining produces each part to your CAD drawing, selecting parameters from your tolerance, finish and quantity requirements.
Does CNC Milling C102 Copper require dedicated tooling?
Most C102 Copper machining work uses standard cutting tools and CNC programs; dedicated fixtures are made only when geometry or volume requires them.
How clean are the edges produced by CNC Milling on C102 Copper?
Machined C102 Copper edges are clean and to specification; edge-break or deburring is added when your drawing calls for it.
Which industries use CNC Milling C102 Copper parts?
CNC Milling C102 Copper parts are used across aerospace, medical, automotive, electronics, semiconductor and general industrial sectors — anywhere precise C102 Copper components are required.
