| 摘要 |
The invention relates to a machine, for the working of the walls which defin e the cavity of a continuous casting mould, with machine-cutting and/or polishing tools (12). The machine comprises a machine stand (1), with an arm (6), for mounting the tool (12), which may be introduced into the cavity and a table (8), for fixing the mould (7) and devices for generating an N.C. controlled relative displacement between the tools (12) and the walls. A rotatory movement of the tools (12) about axes (13), which are arranged essentially transverse to the longitudinal axis of the arm (6), is disclosed , which, in combination with a swinging movement of the arm (6) about the longitudinal axis thereof, permits a high precision in the working, even in the case of a cavity with a taper varying in the longitudinal direction and/ or along the circumference of a section thereof, or in the case of a cavity wit h a particular corner configuration. |
