A method for automatically cutting off a material passage part while reducing manufacturing cost and cycle time. This method includes preparing a cutting device capable of moving in an automatic control coordinate system, placing the molded article without fixing the molded article, detecting a shape of the molded article by a sensor, acquiring a position of the material passage part in the coordinate system, determining a position of a cut spot in the material passage part as a target position in the coordinate system, moving the cutting device in the coordinate system and disposing the cutting device on a work position for cutting the cut spot, and cutting the cut spot by the cutting device arranged on the work position.

A device for cutting a preferably thick-walled, extruded pipe to length, has at least one cutting tool and a receiving unit for the cutting tool. The cutting tool is radially movable in relation to the extrusion axis, is rotatable via a further component about the pipe to be cut to length, in order to cut the pipe to length, and is in operative connection with a ring element, which ring element can be moved via an axial drive, and the depth of penetration of the cutting tool and the path of movement can be defined using an adjustment unit. The depth of penetration of the cutting tool and the path of movement can be defined via the axial drive, wherein toothed rails can be moved more or less in order to achieve the desired depth of penetration.

A skiver for precise removal of outside material from an elongated device, such as a medical catheter or the like, includes a longitudinal recess in a surface and a transverse replaceable blade therein. A removable cover holds the blade in place. In some embodiments, the skiver has a handle extending from the skiver. In other embodiments, an automated mechanism is used to move the elongated device through the skiver.

An apparatus for cutting off plastic profiles which are extruded along an extrusion axis, the apparatus including a tool located on a tool carrier, a pivot arm by which the tool carrier together with the tool can be moved towards and away from the extrusion axis, and a device configured to pivot the pivot arm. The tool is connected to the tool carrier and can be aligned, by an adjustment mechanism, with a plane lying at a right angle to the extrusion axis and/or the tool is connected to the tool carrier and the pivot arm, the pivot arm being mounted on the pivoting device, the pivoting device being an electromechanical drive, and the electromechanical drive including at least one cycloidal gear which is directly connected to an actuator.
