An apparatus for cutting polymer includes a rotor having a base with a first side and a second side opposite the first side. The rotor includes an outer annular wall extending from the first side and defining a number of slots, an inner annular wall defining a number of slots and extending from the first side and surrounded by, and spaced apart from, the outer annular wall. The rotor also includes blades extending from the first side and positioned within the inner annular wall. A circular-shaped stator also defines a number of slots. At least a portion of the stator is positioned in a space between the outer annular wall and the inner annular wall of the rotor.

A processing apparatus includes a cutting blade mounted on a spindle, the cutting blade having a cutting edge for cutting a workpiece held on a holding table, a measuring portion for measuring an edge projection amount of the cutting edge at a predetermined frequency, and a data processing portion. The data processing portion includes a lower limit recording portion for recording a lower limit of the edge projection amount of the cutting edge as an allowable limit for use of the cutting blade, a storing portion for storing blade information including the edge projection amount measured by the measuring portion and a cutting distance traveled by the cutting blade at the time of measurement of the edge projection amount.

The improved detachable cutting assembly used in food cutting machines includes a rotating disc with a window and a pivot hole linked to the rotation axis of the cutting machine. A flap is connected radially to the rotation axis of the cutting machine by its insert ring. The insert ring includes a fixing area in which at least one nut is embedded and on which there is at least one fastening hole coinciding with at least one nut, and a lifting wedge on which a blade is partially embedded, leaving the cutting edge of the blade protruding on the upper face of the rotating disc through the window of the rotating disc. Existing in the fixing area of the rotating disc, there is at least one fastening hole coinciding with the fastening hole and the nut of the flap and capable of fixing the whole assembly by linking elements.

A slicing disc assembly includes a disc body having a top surface, a bottom surface, a central hub, a circumferential edge, a first opening in the disc body between the central hub and the circumferential edge, and a second opening in the disc body between the central hub and the circumferential edge, an adjustable horizontal slicing blade associated with the first opening, the horizontal slicing blade being moveable in a direction perpendicular to the top surface of the disc body, and an adjustable vertical blade assembly associated with the second opening. The vertical blade assembly is moveable between a first position where a slicing element of the vertical blade assembly is located below a plane defined by the top surface of the disc body, and a second position where the slicing element of the vertical blade assembly extends above the plane.

A slitter according to an embodiment of the present art includes: an upper knife disposed above the electrode plate to rotate, thereby cutting the electrode plate; and a lower knife disposed below the electrode plate to partially overlap the upper knife and rotate, thereby cutting the electrode plate together with the upper knife, wherein the upper knife includes: a first inner surface extending to be inclined from a tip formed at the lowermost end to the lower knife; and an outer circumferential surface extending to be inclined from the tip to an opposite side of the lower knife, wherein the first inner surface has an inclination at a first angle from a vertical line V that is perpendicular to a rotation axis that serves as a rotation center of the upper knife, and the outer circumferential surface has an inclination at a second angle from the vertical line.

A cutter is provided for cutting through obstructions disposed in the interior of pipes ranging in size from approximately 8″ to approximately 15″ in diameter or from approximately 12″ to approximately 24″ in diameter. The cutter has been reduced in size relative to known root cutters to be capable of being used with smaller-diameter pipes, but is sufficiently powerful to cut through obstructions, such as mineral deposits, for example, that known flexible cutters capable of being used with these smaller-diameter pipes are incapable of cutting through.

A roof cutter and a method of cutting a roof is provided. The roof cutter includes a basethat is movable between a retracted configuration and a cutting configuration. In the retracted configuration, the blade is displaced from the roof. In the cutting configuration, the blade is positioned so as to facilitate cutting of the roof. The roof cutter includes a stop assembly and an engagement member that is configured to engage with the stop assembly when the base is in the cutting configuration, thereby establishing a maximum cutting depth. A dampening mechanism softens impacts associated with the blade moving to the cutting depth and absorbs vibrations associated with cutting the roof at the cutting depth. An adjustment assembly is configured to selectively adjust the cutting depth and/or to selectively restrain the base in the retracted configuration, thereby preventing the blade from cutting the roof.

A cutting device for cutting a pipe having a pipe wall includes an elongate carrier having a tool end which is engageable with a power tool, and a free end. The device includes a guide wheel located at the free end of the carrier, which is mounted thereon for rotation relative thereto, having a bearing surface extending parallel to a longitudinal axis of the carrier. The device also includes a cutting element having a peripheral cutting edge which is located adjacent to the guide wheel being positioned intermediate the guide wheel and the tool end. The cutting element is of greater transverse dimension than the guide wheel so that when the bearing surface bears against an internal surface of the pipe the distance between the cutting edge of the cutting element and the bearing surface enables the cutting element to cut through the pipe wall.

Disclosed are a cutter assembly and a fruit and vegetable cutter using the cutter assembly. The cutter assembly includes a rotating shaft assembly, a forward-rotating blade and a counter-rotating blade. The rotating shaft assembly has a first mandrel and a first outer shaft. The end of the first mandrel and the end of the first outer shaft are each provided with a first transmission part coupled to a drive device; the blades are respectively arranged in the shaft assembly and perpendicular to the rotating shaft assembly; one blade is coupled to the first mandrel, and the other is coupled with the first outer shaft, so that the blades can be driven by the rotating shaft assembly to rotate in two opposite directions at the same time. The fruit and vegetable cutter includes a fruit and vegetable cavity, the cutter assembly and a driving device for driving the cutter assembly.

A food processor is provided that includes necessary blades and plates to carry out multiple functions of the food processor including slicing, shredding, and grating without having to remove and replace blades and plates to carry out those same functions. The motor of the food processor may operate in either the clockwise or counterclockwise direction. In the clockwise direction, the blades and plates within the cutting chamber may be configured to slice food at variable thicknesses, cut food at variable sizes in a julienne style, or grate food at various thicknesses. In the counterclockwise direction, food may be diced.
