Abstract: The component (2) is first brought into point or line contact with the sheet (3) so as to avoid entrapment of air therebetween. The contact area between the component and the sheet is then gradually spread until the entire bottom surface of the component is adhered to the sheet.

Abstract: A tool changer for machine tools is capable of transferring a tool transfer pot with a stroke smaller than the transfer distance of the tool transfer pot. The tool changer for a combined machining lathe includes a tool magazine having a multiplicity of tools and serving for transferring and indexing a next-process tool to a specified tool takeout position. A tool transfer mechanism transfers the next-process tool positioned in the tool takeout position or the tool delivery position to a tool changing position. A tool changing mechanism changes a process-completed tool loaded on a tool post body with the next-process tool positioned in the tool changing position. The tool transfer mechanism comprises a transfer arm pivotally disposed between the tool delivery position and the tool changing position. A tool transfer pot is coupled to a front-end portion of the transfer arm and serves to support the next-process tool.

Abstract: A processing method and a processing machine for restraining abrupt increase in a load applied to a tool in entering a workpiece and for avoiding decrease in tool's life span are provided. When an end mill EM is entered into a processing surface of a workpiece W, the end mill EM is first entered obliquely to a processing surface of the workpiece W, and is moved oppositely to the entering direction while keeping the cutting depth. Alternatively, the end mill EM is entered obliquely to the processing surface of the workpiece W and is moved oppositely to the entering direction while gradually increasing the cutting depth of the end mill EM. When the cutting depth reaches a predetermined cutting depth, the end mill EM is moved parallel to the processing surface of the workpiece W.

Abstract: A fixing device for fixing a tool, preferably a turning tool, to a toolholder, includes a shank and at least one cutting part. The toolholder has an insertion opening for accommodating the tool shank. The fixing device includes a clamping element which is stored in such a way that it can partially rotate in the holder around an axis of rotation which is perpendicular to the axis of insertion of the insertion opening. The clamping element also includes a partially cylindrical surface section which is eccentric in relation to the axis of rotation. Furthermore, the shank surface has a partially cylindrical, open-edged recess perpendicular to the shank axis, into which recess the clamp element can be screwed by its partially cylindrical surface section when mounting the tool shank.

Abstract: A cable finishing and testing machine incorporates an electrical resistance testing station in a single automated process. The cable finishing and testing machine utilizes a conveyor belt to keep a terminated cable in an outstretched orientation as a trailing terminal of the terminated cable laterally transfers from one processing station to the next. A free or leading terminal of the terminated cable, being in a known sliding orientation upon the belt, is easily located and electrically engaged by a pick-up clamp device. A first indexing station electrically engages the trailing terminal and the electrical resistance of the terminated cable is measured. If the terminated cable tests bad, the terminated cable is automatically transferred to a second indexing station where it is destroyed and scrapped.

Abstract: A tool holder includes a holder body which in turn includes a shank portion, a flange portion, and a tool attachment portion; a taper cone fitted to the shank portion; an elastic member interposed between a rear-end face of the flange portion and a front-end face of the taper cone; and a stopper member disposed on the shank portion so as to support a rear-end face of the taper cone. The outer surface of the taper cone is tapered at an angle equal to that at which the wall surface of a taper hole formed in a spindle of a machine tool is tapered. The inner surface of the taper cone and the outer surface of the shank portion are equally tapered at an angle smaller than the angle at which the outer surface of the taper cone is tapered. Through drawing of the holder body, the taper cone expands radially to thereby be tightly held within the taper hole. A spacer is bonded to the end face of the spindle so as to eliminate a gap which is formed between the flange portion and a spindle.

Abstract: A reamer T including three-stage chip groups 6, each group having five chips 6 disposed circumferentially on a circle of a diameter smaller than an inside diameter of a hole H in a work W, axially at a given pitch P. When the axis Lt of the rotated reamer T is moved circumferentially on a circle about the axis Lw of the hole H after the reamer T is inserted into the hole H in the work W, the three-stage chip groups 6 simultaneously cut an inner peripheral surface of the hole H. When the reamer T is moved in the direction of pulling from the hole H by one pitch P in this state, the three-stage chip groups 6 simultaneously cut the inner peripheral surface of the hole H in the work W respectively by one pitch. Therefore, a boring work for providing the hole H having a depth D=3P in the work W can be completed in a short time.
