More Information
Summary:A machining apparatus for making a plasticizing barrel includes a clamping device for securing the plasticizing barrel, with the clamping device constructed for rotation about a rotation axis and for off-center acceptance of the plasticizing barrel to thereby cause the plasticizing barrel to wobble about its symmetry axis, when the clamping device rotates. The clamping device interacts with a machining unit to provide the plasticizing barrel with an internal conical bore for receiving a screw. The machining unit has a turning tool which is movable linearly back-and-forth in a direction of an axis which extends in relation to the rotation axis at an incline of about half a cone angle of the conical bore, wherein the conical bore being produced has a center line which coincides with the rotation axis.
