摘要： The cutting tool may be employed to shape an internal hole, provide a form to the outer periphery of a workpiece, or shape a hole to a predetermined form while cutting an exterior profile to a desired shape. The tool has a shank with an oval shape flange with a tool-supporting portion having a similar oval shape flange with mating apertures in the flanges. The apertures in the first flange contain a thread while the holes in the second flange are somewhat enlarged. Three set screws are provided in the second flange at each end thereof in engagement with the screws which retain the flanges together. The set screws shift the second flange in any direction relative to the first flange which slopes relative to the axis of the shank so that the tool is offset at an angle to the axis of the shank.

摘要： A rotary cutting tool is provided for cutting an opening in a sheet of material (e.g., drywall) around a pre-installed item (e.g., an electrical box). The cutting tool may include a shaft, at least one cutter, a guide tip and a shoulder formed by a lower edge of the cutter adjacent the guide tip. The shoulder may have a width that corresponds to the width of a wall of the pre-installed item. The width of the shoulder may be equal to the width of the wall, or it may be slightly greater than the width of the wall. The guide tip may include a bearing to prevent marring of the wall of the item when the guide tip is rotating and in contact with the wall. An adjustable collar and corresponding bearing may also be disposed around the shaft for controlling a preferred cutting depth of the cutter. The cutting tool may be engaged with any suitable rotary tool, including one having an adjustable table for controlling a preferred cutting depth of the cutter. Related methods of using a cutting tool to cut an opening for receiving the item or box are also provided. The rotating guide tip may be moved into contact with the wall and the shoulder may be positioned above and/or in contact with an upper edge of the wall. The cutting tool is then moved around the wall while rotating to cut an opening in the material through which the item or box may be positioned.

摘要： A method is provided for producing a ventilation bore in a thrust bearing of a crankcase of a reciprocating internal combustion engine by milling. The milling cutter is an angled-head milling cutter, which is introduced into the crankcase in the direction of a cylinder longitudinal axis and is moved in the direction of a crankcase longitudinal axis until the thrust bearing is perforated. Subsequently, the angled-head milling cutter is moved back in the direction of the crankcase longitudinal axis and removed from the crankcase by moving the angled-head milling cutter in the direction of the cylinder longitudinal axis. Internal stresses in the crankcase are avoided by the production of the ventilation bore, as a result of which the strength of the crankcase is increased.

摘要： An end mill 10 is a tool for milling a metal block such as a metal mold and is placed in a machine tool such as a milling machine when in use. The end mill 10 is used to provide a rotary milling cutter and a milling method using the same, in which it is possible to perform orthogonal milling and pocket milling to efficiently form four corners with small radius, without repeatedly milling using a small-diameter end mill. The end mill 10 has two cutting edges 11a and 11b at its distal portion, and an edge angle D1 formed by the two cutting edges 11a and 11b is 70.53 degrees.

摘要： An adjustable depth router is particularly suited for routing openings in ducts beneath register openings in a floor, without use of router bit extensions. A small diameter pneumatic motor, whose casing is mounted at the lower end of an elongated air supply casing of the same diameter, holds the router bit at its lower end; this assembly is vertically adjustable in a router frame. When routing through a floor opening, the base is rested on the floor, the cylindrical assembly projects through the floor opening so the router bit will operate at the desired depth therebeneath; and the bearing of the cylindrical assembly against the edge of its floor opening guides the router. An opening is thus routed parallel to the floor opening and spaced inwardly by the difference between the radius of the casing and the radius of the router bit.

摘要： A trunnion for toroidal continuously variable transmission, includes: an oblique surface, a bottom surface, an inclining shaft having an end surface and an inclining end surface, a pivot hole, an inner flat plane, and a crossing lubrication hole. The trunnion is obtained by supporting a trunnion material taking the oblique surface or the bottom surface as a machining reference and taking one of the end surface and the inclining end surface as an axial positioning reference, and by machining the trunnion material to form the inner flat surface, the pivot hole and the crossing lubrication hole of the trunnion while keeping the trunnion material retained.

摘要： An eccentric boring tool and method of forming a bore off center from the central axis of a workpiece are disclosed. The tool includes a tool holder nonrotatably supported relative to a workpiece and an outer housing supported for rotation with the workpiece and rotation relative to the tool holder. An eccentric supported within the housing mounts a bearing which in turn supports the tool holder. The eccentric rotates with the housing causing the longitudinal axis of the tool holder to orbit about the longitudinal axis of the workpiece. An end mill cutting tool is supported in the tool holder. A plurality of discs are supported in the forward end of the housing. The discs engage the workpiece, lock the housing to the workpiece and cause the housing to rotate at the same speed as the workpiece.
