ABSTRACT:
An X-Y coordinate carriage for a routing machine with which such a routing machine can be retrofitted. The coordinate carriage includes a cross-carriage and a longitudinal carriage having a torsion- and bending-resistant frame of lightweight construction, displaceably guided by mutually spaced bearings on a guide shaft mountable laterally to a worktable of the routing machine and supported on an opposite side of the worktable by a support roller against a support rod fastened laterally thereto and running parallel to the guide shaft. Guide shafts and retaining blocks support and guide the cross carriage, and bearing blocks are provided for displaceable mounting the cross carriage. The bearing blocks are disposed in spaces between hollow members of the longitudinal carriage and the cross carriage, whereby the guide shafts run approximately at a level of longitudinal horizontal center plane of the hollow members of the longitudinal carriage. Bearing bearing shells of slide bearings, by which the longitudinal carriage is displaceably mounted on the longitudinal guide shaft and the cross carriage is displaceably mounted on the longitudinal carriage, are cast in bores in bearing blocks having inside diameters greater than outside diameters of the bearing shells.
