Processing of CAROBRONZE^®

Machining

Carobronze^®-bars and tubes are produced with narrow tolerances of diameter and straightness. This permits very good processing on automatic lathes. However, Carobronze^®, as a homogenous, tough material with high strength is not an easily machined copper alloy. This material produces flowing chips. Therefore, in order to achieve optimum processing results, the choice of the cutting material and the tool geometry is of the greatest importance.

For turning Carobronze^® we recommend the use of disposable hard metal inserts K10 with aluminium geometries.

Cutting speed:

• Roughing up to 400 m/min

• Smoothing up to 600 m/min

Advance:

• Roughing up to 0,45 mm/rev

• Smoothing < 0.02 mm/rev (dependent on the required surface condition)
