The aim of the project was the processing of sawn square rods consisting of high strength copper wrought alloys with a tensile strength of 600 – 1200 N/mm². During peeling, the rods had to be modified into round semi-finished products.
According to the customer’s requirements, we developed a special-purpose machine that facilitates parallel peeling of square rod material 15 to 80 mm at a length of 5.000 mm. The peeling diameter is adjustable during operation, so that diameters can be corrected, if applicable.
The centerpiece of this special-purpose machine is a specially developed NC-controlled peeling chuck with six cutting edges to ensure quiet running during the peeling process.
Machining constituted a special challenge of this project. Because water and oils would contaminate the chips and consequently prevent the re-processing into high quality alloys, like f. e. beryllium, dry machining without coolant had to be performed.
