The process

rollfeed® turning enables the rollover of insert contour being a cutting edge on rotationally symmetrical surfaces of any shape. Rollover motion is generated by rotation of the tool with simultaneously compensation of arising center offset by X- and Z-axis of the machine-tool. The unrolling feed synchronously overlays the contour parallel feed rate. By utilization of known cutting materials rollfeed® turning can be applied in all known work piece materials.
