Abstract

721,102. Tool grinders. FLUCKIGER, W. May 12, 1953 [May 31, 1952], No. 13246/53. Class 60 A machine for grinding cutting tools such as turning tools, milling cutters and the like comprises a frame 1 and two movable parts carried thereby. The first movable part carries the tool to be ground and comprises an angular shaped support 2 one of the arms of which is vertical and slides in a guide integral with the frame and arranged on the inside thereof, whilst the other arm is horizontally arranged above the frame. The support 2 is vertically adjustable by a handwheel 7. A tool carrier 5 is mounted on the horizontal arm 2 and is movable therealong by a handwheel 6. The carrier carries a vice 9 into which the tool 10 to be ground is fixed; the vice has a semi-cylindrical box fitting a correspondingly shaped recess in the carrier, enabling the tool to be pivoted around an axis cross-wise to the tool and parallel to the direction of movement of the carrier 5. The second movable part comprises the grinding head 3 which consists of an electric motor 22 driving, through a belt, a grinding wheel 11 mounted on a spindle of the expansible type to facilitate changing of the grinding wheel. The motor, spindle and transmission are enclosed in a casing provided with ventilation slits. The grinding head is mounted so as to be pivotable about a horizontal axis y-y on the upper end of the vertical arm of an angular piece 12, the end of the horizontal arm of the angular piece being fixed to the upper end of a piece mounted in a vertical groove in the frame and also adopted to turn about a vertical axis x-x which intersects the axis y-y. The movements of this sliding and rotating piece and consequently of the grinding head 3 may be obtained either manually by the operation of handwheel 8 or selectively either by hand or by means of a motor located inside the frame. An electromagnetic coupling arrangement acting on the members of a transmission mechanism placed between the handwheel 8 and the motor on the one hand and the sliding and rotating piece on the other hand makes it possible to effect either vertical movement or angular movement of this piece. Adjustable stops are provided to limit the extent of these movements. Scales 16, 17 are provided for determining the angular movements of the head 3 about the axes y-y and x-x.
