The present invention relates to a cutting bite and a cutting apparatus including the same. According to one embodiment of the present invention, a cutting bite is provided to sequentially pass through an upper end portion, a central portion, and a lower end portion of stacked films in a thickness direction of the stacked films when a rotating wheel rotates, and is provided such that cutting is performed in a manner in which a cutting direction of a cutting tip is a direction from an outside toward an inside of the stacked films while the cutting bite passes through the upper end portion toward the lower end portion.

Cutting apparatus

The present invention relates to a cutting device and a chamfering machine comprising the same, and according to one aspect of the present invention, a cutting device for use in a chamfering process of a film laminate is provided, in which the cutting device comprises a rotating wheel having a rotation center; and a cutting bite comprising a main body mounted on the rotating wheel and a cutting tip provided on the main body and provided to perform chamfering of the film laminate by rotating the rotating wheel, wherein the cutting bite is mounted on the rotating wheel such that the central axis of the cutting tip is inclined at a first angle with respect to the tangential direction of a rotation locus of the cutting bite formed by rotating the rotating wheel.

Cutting device and chamfering machine comprising the same

The present invention relates to a viscosity measurement device. According to one aspect of the present invention, provided is a viscosity measurement device comprising: a housing which has an inlet port, an outlet port and a measurement space positioned between the inlet port and the outlet port; a magnetic body arranged in the measurement space; an electromagnet for moving the magnetic body; a position measurement part for measuring the position of the magnetic body; a flow rate measurement part for measuring the flow rate of fluid which flows in the measurement space; and a control part for measuring the viscosity of the fluid on the basis of the strength of a magnetic field generated by the electromagnet and the shear strain rate of the fluid which passes through the measurement space.
