MACHINE FOR CUTTING PRODUCTS IN SLAB FORM, PROTECTION DEVICE AND OPERATING METHOD

摘要

A machine (10) for machining materials in slab form (14) comprises a working surface (13), a cutting spindle (12) on which a cutting disc (22) is mounted, motor means (11) for moving the cutting spindle on the working surface, controlled by an electronic control system (23). The cutting spindle (12) is rotatable about an axis (21) so as to move upon command between a first position in which the cutting disc (22) is perpendicular to the working surface, and a second position in which the cutting disc (22) is parallel to the working surface. The cutting spindle (12) has a protection device (26) which covers at least partially the cutting disc and which comprises a pick-up element (27) with a surface (28) provided with sucker means (29) able to cause said device (26) to adhere and be fixed to the materials being machined on the working surface when the cutting spindle (12) is in the second position, so that the material can be moved on the working surface by moving the cutting spindle (12). The said pick-up element (27) is resiliently movable with respect to the protection device in the direction of action of the sucker means.
