  • the configuration of the auxiliary element 4 also allows a certain versatility of the machine 1 , on which more auxiliary elements 4 of different dimensions can also be mounted alternatively in such a way as to form different processing intensities and/or qualities, and in any case the machine 1 is also suitable for a convenient replacement of the auxiliary element 4 for being able to obtain other types of machining operations. It is also possible to minimise the waste due to the rejection of material which accidentally escapes from the working path L1 or L2, using a cleaning element 11 which efficiently acts in conjunction with the other components of the machine.
