公知である。 Conventionally, a blade supported by a blade holder and rough and finishing whetstones for polishing the blade are provided correspondingly.
A woodworking knife polishing machine in which one of the blades is reciprocated by a reciprocating means to perform rough sharpening and finishing sharpening of the cutter by means of a whetstone is known from Japanese Patent Laid-Open No. 139863/1983.

つた。 However, as is clear from the description in Figures 2 and 3 of the drawings, in this case, the rough whetstone and finishing whetstone are arranged so that their horizontal center lines coincide with the center of the width of the part to be ground of the blade. Therefore, as shown in Figure 10A of the drawing, the blade surface of the knife is ground with a rough whetstone to completely remove any chips etc. from the cutting edge.
In order to sharpen the tip of the cutting edge slightly using a cup-shaped finishing whetstone as shown in Figure B,
As is clear from the descriptions in Figure 10A and B, the supporting angle of the blade must be changed for rough sharpening and for finishing sharpening, which makes the operation cumbersome and reduces work efficiency. When adjusting the sharpening angle by changing the support angle, there is a problem in that a slight angle error occurs each time the adjustment is made, resulting in variations in the sharpening angle.
そこで、本考案は荒砥石と仕上砥石との刃物の
被研削面に対する傾き角を若干相違させることに
より、前記した従来の問題点を解決させた木工用
刃物研磨機を提供するものである。 Therefore, the present invention provides a woodworking knife polishing machine that solves the above-described conventional problems by slightly different inclination angles of the rough whetstone and the finishing whetstone with respect to the surface to be ground of the cutter.

である。 When using a cup-shaped rough whetstone 9 and a finishing whetstone 10 as shown in Figure 2 of the drawing, the rough whetstone 9 is attached to the surface to be ground of the cutter 7 at a sharpening angle α 1 as shown in Figure 3. Correspondingly, a motor 1 drives a rough whetstone 9 so that the finishing whetstone 10 corresponds to the surface to be ground of the cutter 7 at a sharpening angle α2 .
1 and the motor 12 that drives the finishing whetstone 10 are attached to the holders 13 and 14 so that the axis of the motor 11 is inclined toward the blade base by θ from the axis of the motor 12. When polishing the blade 7, first send the rough whetstone 9 to the blade 7 to roughly sharpen the blade edge, then pull up the rough whetstone 9 and send the finishing whetstone 10 to the blade 7 to finish sharpen the blade edge. , while holding the knife 7 at a constant angle, roughly sharpen the knife 7 at α 1
Finishing sharpening can be done easily and reliably at an angle of α 2 .

を奏するものである。 As mentioned above, the woodworking knife polishing machine according to the present invention uses a rough whetstone and a finishing whetstone, which are placed opposite each other on a cutter held at a predetermined angle by a cutter holder, so that the rough whetstone is tilted toward the base of the cutter. The angle of the finishing whetstone is set smaller than the angle of inclination towards the cutting edge of the cutting tool, so just by keeping the cutting tool fixed and cutting between the rough and finishing whetstones, the cutting tool will Not only is it possible to easily and efficiently perform rough sharpening and finishing sharpening at different angles to achieve the ideal blade sharpening, but it is also possible to easily and efficiently perform rough sharpening and finishing sharpening at different angles. When setting the sharpening angle with , the angles of rough sharpening and finishing sharpening are always the same and there is no variation, and even when changing the blade edge angle by adjusting the inclination of the knife holder, the rough sharpening This has the unique effect of keeping the difference in angle between finishing and finishing sharpening constant.
