The cutting tool for materials, in particular made of polyurethane elastomers, which is controllable manually or program-controlled comprising a cutting head (10) with a driving device (20), a blade holder (30) with a cutting knife (35) has at least one cutting head, whereby the driving device (20) is configured in a way known in itself or consists of a driving motor (21) with a drive shaft (22) running in cutting head longitudinal axis (L), a cam disk actively connected with the drive shaft (22) of the driving motor (21), driven rotating about the drive shaft longitudinal axis (L2), with control surfaces (40, 41) configured on the side (25a) opposed to the driving motor (21) and lying in different planes, a roller (26) actively connected with one of the control surfaces (40. 41) of the cam disk (25), a lifting rod or tappet push rod (45) actuated by means of a spring (27) which is actively connected with the roller (26) and the cam disk (25) over a coupling piece (46) and which carries at its free end (45a) the blade holder (30) for the cutting knife (25).
A cutting tool for materials, in particular made of polyurethane elastomers, which is controllable manually or program-controlled, comprising at least one cutting head (10) with a blade holder (30) and a cutting knife (35) that is stationary or controlled by a driving device (20) so that the blade holder (30) with the cutting knife (35) is movable to-and fro along a cutting head longitudinal axis (L), a feeding pipe (150) is arranged to guide a separating agent (160) to the cutting knife (35) during a cutting operation, which separating agent prevents gluing of the edges of the cut after cutting, wherein the separating agent is a dispersion of waxes or oils and silicones in a solvent mixture, the feeding pipe (150) is placed on the cutting head (10) or in the cutting head (10) and has an outlet end (150b) adjacent the cutting knife (35) or an outlet opening (156) connecting to a bore hole (155) formed in the cutting knife (35), the outlet openings (156, 150b) lie in the cutting and separating region of the cutting knife (35), the separating agent being fed by the feeding pipe to the cut, the feeding pipe (150) being connected at one end with a micro metering system (170).
