Described is a device for removal of excess material from a test sample. The test sample may be used in an instrument for measurement of rheological and mechanical properties sample properties. The device includes a test geometry and a trimming ring. The test geometry includes a lower geometry and upper geometry each having a circular outer edge and being centered on an axis of rotation. The trimming ring has a sidewall, a ring axis coincident with the axis of rotation and at least one cutting edge disposed along at least a portion of a circumference of the trimming ring at a diameter that is at least as great as a diameter of one or both the lower geometry and the upper geometry. The device further includes an actuator coupled to the trimming ring and configured to translate the trimming ring in a direction parallel to the axis of rotation.

A slicing machine for cutting slices of a food product includes a machine housing including a circular blade configured to rotate in a cutting plane, a stop plate configured to be move, by an adjustment device, perpendicular to the cutting plane, a carriage mounted such that it is movable parallel to the cutting plane, and a machine status display for displaying an actual status of the slicing machine.

A method monitors a slicing machine, which has a circular knife driven by an electric knife motor. The method includes: sensing a knife motor current or a temporal profile of the knife motor current from the electric knife motor; determining measurement data based on the knife motor current or the temporal profile of the knife motor current; and determining a current cutting characteristic value based on the measurement data. The measurement data includes a load-dependent or load-independent current component. The cutting characteristic value includes a soiling, wear, or knife sharpness characteristic value, the soiling and wear characteristic values being derived from the load-independent current component, and the knife sharpness characteristic value being derived from the load-dependent current component.

A cutting device and corresponding method for cutting a relatively rigid material), such as for example paper, cardboard, plastic material, composite or other. The cutting device includes a first cutting disc sharpened along its peripheral edge and rotating around its a first axis of rotation. A second cutting disc, also sharpened along its peripheral edge (and rotating around a first axis of rotation (X3), is disposed in front of the first cutting disc with respect to the material and is co-planar with the first cutting disc (14).

There is provided a cutting machine for cutting a wafer using a cutting blade. The cutting machine includes a shape storage section, a shape measurement unit, a determination section, and an end face correction device. The shape storage section stores a cross-sectional shape of a support surface, which a mount of a cutting unit has, in an axial direction of a spindle. The shape measurement unit contactlessly measures the cross-sectional shape of the support surface in the axial direction of the spindle. Through a comparison between the cross-sectional shape stored in the shape storage section and the cross-sectional shape measured by the shape measurement unit, the determination section determines whether or not the support surface needs a correction. The end face correction device corrects a shape of the support surface.

A cutting apparatus includes a chuck table for holding a workpiece thereon, and a cutting unit for cutting the workpiece held on the chuck table. The cutting unit includes a spindle, a mount base fixed to a distal end of the spindle and having an annular coupling face extending around an axis of the spindle and external threads on a distal end portion of the mount base, a ring-shaped ring mount coupled to the coupling face of the mount base and having an annular support surface supporting a surface of an annular base of a hub blade, a coupling mechanism coupling the ring mount to the coupling face of the mount base, and a nut threaded over the external threads of the mount base.
