ABSTRACT:
A machining unit, typically for wood panels, features a work table afforded by a body of prismatic geometry having at least two faces and rotatable about an axis which is also its instantaneous center, in such a way as to establish at least two movable and tiltable work surfaces; the prismatic body is carried within a frame encompassing the tool and combining with the two faces to create respective independent work areas, one in which panels are fed to and from the unit, the other coinciding with a station at which machining takes place, and where the waste and chips generated by machining are cleared from the table and the work. The prismatic body also functions as the main barrier separating two work environments, the one an open external space occupied by the operator, the other an enclosure disallowing access to the operator while machining is in progress.
