CUTTER FOR DIVIDING SEVERABLE MATERIAL

摘要

1. Cutter comprising a cutting tool (1) and a drive means (2, 3, 4) moving said cutting tool, a driven piston (2a) of a working cylinder (2) forming at least part of the cutting tool mount, and a control and regulating device (3, 4, 12-24) for adapting the amplitude and/or frequency of the cutting tool to preset quantities, such as the nature of the material to be cut or the cutting tool feed, characterized in that the piston (2a) of the working cylinder (2) is hydraulically controlled by the control device by means of a pulse generator (3) driven by a control motor (4), the control and regulating device having a regulating circuit (14-19) which, by means of displacement and/or speed transducers (12), establish the instantaneous value of the amplitude and/or frequency of the cutting tool (1) and regulates same to a presettable desired value.
