- the base frame in formed essentially O-shaped and surrounds the first Carriage, wherein the first carriage also substantially O-shaped and surrounds the second carriage.
- the sleds are with respect to the base frame in an open rectangular frame construction telescopically nested.
- Such a configured device has a compact design due to the through the O-shaped configuration of the base frame and the first sled conditional closed Force flow has a very high rigidity, which allows in the case of delivery movements and - where technologically possible - also at the feed movements higher speeds and Accelerations to drive than in conventional edging machines was possible.
- Investigations of the applicant have shown that the times required for edge processing contrasted by the inventive design of the device the known edge processing machines in comparable Edge processing tools (grinding wheels, milling cutters or combinations thereof) significantly reduced and thus productivity can be increased significantly without this would be detrimental to the quality of the processing.
- Even with longer Use, as usual in industrial production becomes one consistently good machining quality achieved because the O-shaped Training the base frame and the first carriage also provides for a thermal symmetry in which by the heating of the involved drive and processing components compensate each other occurring thermal expansion.
- each side of the base frame each have a linear guide provided for the first carriage, wherein the linear guides on the base frame parallel to each other.
