system for selective support for machine tools.

摘要

The present invention relates to a selective support system (10) for a machine tool of the type comprising a first holder (1), a second holder (2) which, after the first holder (1) is arranged, so that a support plane (a) is defined, and in a processing unit (4) for machining a workpiece (p) by means of the crossing of the workpiece (p). This selective support system (10) can be between the first holder (1) and the second holder (2) are arranged and comprises: a plurality of support elements (6, 11), in order to provide a support for the workpiece located in machining (p), conveying means (12), around each support element of the plurality of support elements (6, 11) independently between a respective raised position, in which the support element in the use of essentially with the support plane (a) is aligned, so that there is a support for the workpiece located in machining (p), and a respective lowered position, in which the support element in use in a predetermined distance under the machined workpiece (p) is arranged, so that between the support element and the machined workpiece (p), a free space is defined, which means it is of the machining unit (4) is made possible, a machining with crossing of the workpiece (p) to carry out.
