A numerically controlled milling with the surface pressure - and / or under pressure possibilities

摘要

A numerical control router comprises a head structure (3) provided with a process head (4) having a main shaft motor with a rotary shaft for fixing a tool (7) of a drill or cutter, the head structure (3) being movable on a first rail (2) which is provided with a supporting bed (1), and a suction table (9) being movable on a second rail (8) which is provided with the supporting bed (1), whereby a sacrifice board (13) and a process board (14) are movable on the suction table (9) relatively to the head structure (3), characterised in that a supporting frame (17) is also provided with the supporting bed (1), the supporting frame (17) mounting apparatus for providing press and/or suction action with respect to at least the sacrifice board (13) and/or the process board (14), there being for example press members (22) and suction ducts (25).
