Micro milling of pure copper ScienceDirect
Oct 03, 2001· Tool wear under dry test condition was analyzed with respect to speed, feed and depth of cut. More than 80 tools were tested at different cutting conditions while machining pure copper with micro end mill tool of 1 mm cutter with uncoated carbide cutters of helix angle 25° and 30°. The cutting speed varied from 8000 to 29,000 rpm.

Machining Copper Beryllium Materion
same advantage in machining copper beryllium as other alloys. Carbide tools can be used to a greater advantage if production runs are long and/or close dimensional tolerances must be maintained. Because of the machining characteris tics of all copper beryllium alloys, cutting tool life is excellent. Normally the tool life end point is a wear

Soldering of Copper and Copper Alloys: Part Two :: Total
Impossible to solder even with inorganic flux – if significant oxidation is visible, due to surface film of zinc oxide. Barrier plating of more than 3μm nickel or copper is recommended for preserving solderability during shelf-life (should prevent zinc diffusion to surface). Barrier of 5μm necessary if brass is a lead free-machining grade.
