Passed to the arcuate row of teeth 2 2 3 of the plate body i 2 3, thereby calling the movement stroke of the tooth 1 2 1 3 A on the curved track to determine the table 1 2 above it The moving position is as shown in Fig. 7. In addition, as shown in Figs. 8 and 9, the grinding machine grinds the curved ore cutter 3 2 placed on the processing platform through the grinding wheel device 4 thereon. Cutting, and by means of the above-mentioned arc movement of the table 2, a pair of set tooth positions are ground, and the grinding device is moved in and out by the above-mentioned hydraulic driving. Thus, the grinding of the fox-shaped ore piece 1 3 2 is completed. 201130602 Of course, in order to make a deviation after the adjustment, and by positioning _ In the case of vibration during grinding, etc., table i 2 moves to be grounded == part 3 i is in the above work. When the control of the control unit causes the standing, the positioning holes 1 22, ... 3 1 through 2 are inserted upwards on the table. i 1 2 2 produces the positioning effect., 6 ® is shown, so that the workbench is additionally, when the pair is finished. After the cutting is completed, the control: For example, the machine 2 of the 2糸Send the §fl number to drive the large-angle movement of the corner, and then ==12 A to directly reset the effect, in which the related components of the interlocking unit generate the splicer 2 2 the upper and lower discs 22 : Through f = the unit moves the electronic system to a greater extent than the above. The clutch control 5 achieves the above-mentioned combination of the present hair cutter, the transmission shaft, the linkage member, and the workpiece-to-tooth-toothed member, and the stroke demand of the row of grinding Corresponding arc scale 2 =: Arc-shaped ore on the cutting platform for grinding. Furthermore, the present invention is a precision transmission that allows the setting of the t-flat on the stage to be as follows: the curved silver piece) the tooth to be ground (four) tooth position can be i =克服 Overcoming the conventional technology can not be applied to (10) the ore piece = vertical position error, cutting and boring and other problems. Based on this, in the grinding 1 raw = set: in the process 'relative: will have better convenience in production It is to be understood that the present invention is not limited to the present invention, and the numerical value is changed or equivalent. The replacement of the components is still subject to the scope of the present invention. From the above detailed description, it will be apparent to those skilled in the art that the present invention can achieve the foregoing objects and is in accordance with the provisions of the Patent Law.
