Abstract
A system includes a component to be machined, the component having a plastic base body having an outer diameter and a longitudinal axis and at least one clamping auxiliary structure, and a clamping element configured to clamp the component using the clamping auxiliary structure. The clamping element includes at least one clamping jaw having at least one counter-clamping auxiliary structure that is configured to engage the clamping auxiliary structure and to fix the component in an interference-fit manner in the axial direction with respect to the clamping element. Also a machining method using the system.
Claims16
A system comprising:
- a component to be machined, the component comprising a plastic base body having an outer diameter and a longitudinal axis and at least one clamping auxiliary structure;
- and
- a clamping element configured to clamp the component using the clamping auxiliary structure,
- wherein the clamping element includes at least one clamping jaw including at least one counter-clamping auxiliary structure, the counter-clamping auxiliary structure being configured to engage the clamping auxiliary structure and to fix the component in an interference-fit manner in the axial direction with respect to the clamping element.
A component configured to be machined, the component comprising:
- a base body made from a plastic and comprising a circular cylinder, a circular hollow cylinder, a circular cone, a circular hollow cone, or a truncated cone, the base body having a longitudinal axis and a diameter;
- and
- at least one clamping auxiliary structure including at least one elevation and/or at least one recess with respect to a surface of the component, which surface is adjacent to the at least one clamping auxiliary structure in the axial direction.
A method comprising:
- providing a cylindrical body to be machined, the cylindrical body having an outer diameter and a longitudinal axis of rotation and being formed of a first material, the first material comprising a plastic;
- providing an adapter comprising a band of a second material different than the first material, the band comprising an axially extending surface configured to contact the cylindrical body and a radially extending surface configured to extend radially away from the cylindrical body when the axially extending surface contacts the cylindrical body;
- welding the band to the cylindrical body;
- placing the cylindrical body and adapter in a clamping chuck having at least three jaws such that a portion of each of the at least three jaws extends radially over the radially extending surface and clamping the cylindrical body using the at least three jaws;
- rotating the clamping chuck to rotate the cylindrical body;
- and
- machining the cylindrical body.
