Channelling

We use channelling primarily as a method for manufacturing internal profiles. It involves a rod-shaped channelling needle being pulled through the bore of the part to be machined, which is held in a clamp. The needle is equipped with cutting teeth that project to an increasing degree and gradually produce the required contour.

The clearing needle is a multi-cutter, geometrically defined, linearly mobile tool, of which not all cutters are operational. The complicated internal contour with a fixed dimension is machined by pulling the tool through the given part. If the contour dimensions are changed, the entire tool has to be replaced.

Available contour options include

tapered grooves
standard and non-standard hub profiles
internal toothing
