摘要： An active safety apparatus adapted for a disk or circular knife or saw is based on optical surveillance apparatus. The apparatus provides a precise boundary for a protected volume surrounding the blade. The apparatus creates four corner edges for the protected volume, which is a cuboid or a right frustrum. Appearance of an operator hand, recognized by glove color, in the protected volume causes immediate, active stopping of a servomotor used to rotate the saw blade.

摘要： A cutting liquid supply unit of a cutting apparatus includes a pair of gutter forming nozzles that are disposed to face each other in such a manner as to sandwich a cutting blade and that supply a cutting liquid to the cutting blade to form gutters extending in a processing progression direction, and a tip nozzle that supplies the cutting liquid from the outer circumferential side of the cutting blade toward the cutting blade on the upstream side in the processing progression direction. The tip nozzle supplies the cutting liquid toward a processing point at which the cutting blade cuts into a workpiece, and guides the cutting liquid by the gutters toward the downstream side in the processing progression direction.

摘要： In order to be able to safely remove the heavy and very sharp blade from the machine, which is overhanging when mounted, in contrast to known solutions, the entire cutting unit is not swung out of the machine so far that the blade is easily accessible, but instead the cutting unit together with the blade support and blade drive remain unchanged in position in the machine, and only the blade carrier of a mounting device is brought into contact with the blade.
Then the blade can first be fixed to the protective blade carrier before the connection of the blade to the blade support is released, and then the blade carrier loaded with the blade can be removed from the machine in a simple manner, for example pulled out sideways.-

摘要： The present invention discloses a pile head girdling device comprising a track arranged on a pile head and coaxial with the pile head, an electric saw installation base arranged on the track in a sliding mode, an electric saw support rotationally arranged on the electric saw installation base and an electric saw arranged on the electric saw support. The beneficial effects of the present invention are as follows: according to the solution, the electric saw cutting position on the pile head is effectively controlled on the same plane, thereby improving the quality of cutting the pile head; and the electric saw cutting position is guided and limited by means of the track, thereby improving the cutting efficiency and precision.

摘要： Dynamic regulation of contact pressures in a blade sharpening system is provided. An example multiphase grinding wheel has a grinding face with one or more abrasive concentric rings for sharpening the cutting blade of the log saw machine, and one or more padded concentric rings consisting of fiber padding. Sharpening with the multiphase grinding wheel improves cut quality, increases blade life, removes glues and varnishes from the cutting blade, reduces blade deformation, and hones the edge of the cutting blade. A pneumatic tensioning system uses air bladders to apply dynamic cushioning and processor-controlled contact pressure between the grinding wheels and the cutting blade during sharpening. The fiber-padded grinding wheels and the air bladder tensioner provide improved sharpness of the cutting blade and longer life for the mechanical components.

The fiber-padded grinding wheels and the air bladder tensioner provide improved sharpness of the cutting blade and longer life for the mechanical components. The padded grinding wheels decrease fire risk, and the tensioner can be operated remotely, decreasing human injuries common with conventional setup actions near the sharp cutting blade.

摘要： Methods, apparatus, and systems for cutting material used in fused deposition modeling systems are provided, which comprise a ribbon including one or more perforations. Material is passed through at least one perforation and movement of the ribbon cuts the material. A further embodiment comprises a disk including one or more blade structures, each forming at least one cavity. Material is passed through at least one cavity and a rotational movement of the disk cuts the material. A further embodiment comprises a slider-crank mechanism including a slider coupled to a set of parallel rails of a guide shaft. The slider moves along a length of the rails to cut the material. Yet another embodiment comprises one or more rotatable blade structures coupled to at least one rod. The rotation of the blade structures causes the blade structures to intersect and cut extruded material during each rotation.

摘要： A hand-held cutting tool includes a cutting member, a motor, a housing, a baseplate, a drive shaft, a transmission device and a shield. The motor has an output shaft rotating around a first axis. The housing is provided with a handle portion. The baseplate having a supporting surface connects to the housing and is rotatable about a second axis. The drive shaft drives the cutting member to rotate around a third axis perpendicular to the first axis. The shield encloses at least in part the cutting member in a circumferential direction of the third axis. The first axis obliquely intersects the supporting surface. The supporting surface is parallel to the third axis. The shield and the handle portion are disposed on a same side of the supporting surface. The second axis is parallel to the third axis.
