に研磨することができるものである。Therefore, both sides of the tooth throat of the saw tooth are ground parallel to each other, and the tooth throat is ground to a constant width from the tooth tip to the tooth root, and the required upper tooth advance angle is set by the included angle of the pair of grinding wheels. The grinding wheel, which is given and has been removed from the saw tooth, is moved from the grinding position to the standby position by the first feeding means, and the second feeding means returns the grinding wheel, which has been removed from the saw tooth, to the position of the saw tooth. During this time, if you send out the band saw using the saw feeding means and change the saw teeth that have been ground and the saw teeth that have not yet been ground, you will be able to properly learn the 10-tooth clearance angle by aligning the tooth throats of a large number of saw teeth with a constant width. It can be polished continuously.

第3の各カム33 、35 。To polish the side surface of the saw tooth 3' using the side polisher of the band saw shown in the embodiment, first, as shown in Figure 1, screws for fixing the fan-shaped swing plate 8 and the fan-shaped adjustment plate 10 are removed. ■ 13
When the adjustment plate 10 is rotated to the left in the figure around the support shaft 11, the depression angle of the grinding wheel holder 17 attached to the adjustment plate 10 by the support shaft 14 becomes large; This changes the inclination of the grinding wheels 28, 28 supported by the grinding wheel holder 17 with respect to the saw teeth 3'. Both in the case of , and in the small case of Fig. 13, the inner circumference can be adjusted so that it is parallel to the tooth throat.
When this adjustment is completed, the screw 13 is tightened to fix the adjustment plate 10 and the swing plate 8, and the grinding wheel 28 is moved by the motor 27°27.

挽六曲りをも生じにくい形に側面研磨される。At this time, the second cam 35 is connected to the second grinding wheel feed lever 2.
9 is driven, and transmission is transmitted from the small lever 30 to the small lever 31 through the opening 9 door 32, thereby moving the grinding wheel holder 17 from the position shown by the solid line in Figure 2 to the position shown by the chain line. Therefore, the grinding wheel 28.degree. 28 moves upwardly along the tooth throat of the sawtooth 3' as shown in FIG. 1, and disengages above the sawtooth 3' as shown in FIG. For this reason, both sides of the sawtooth 3' are ground so that they are completely parallel when viewed from the front.
As shown in Figure 1 O of the drawing, the width of the tooth throat is constant from the tip of the tooth to the root of the tooth, and due to the included angle given to the grinding wheel 28° 28 when viewed from above, As shown in the figure, the side surface of the workpiece is ground into a drumstick shape with the desired upper tooth advance angle, so that the ground surface of the workpiece is smooth and beautiful, and it is difficult to cause bending.

At this time, the first cam 33 returns the grinding wheel holder 17 to the rear, and the second cam 35 moves it downward, so that the grinding wheels 28, 28 return to the waiting position, and the grinding wheel holder 17 returns to the waiting position. After being fed forward by the first cam 33, when being pulled forward by the second cam 35, the side surface polishing operation is repeated to uniformly polish the side surfaces of all the saw teeth 3'. It is something that

材を円滑に行うものである。Therefore, when sawing material using the band saw 3 whose side surface has been polished by this polishing machine, the side surface of the saw blade 3' hits the sawn surface flatly, so the sawn surface is cut smoothly and beautifully, and the sawn surface and the side surface are separated. The direction of the sawtooth 3' is regulated by the line contact of the sawtooth 3', allowing smooth sawing of material with sharp bends.

とができる。(g) Effects of the Invention The band saw side grinder according to the present invention cuts into the saw tooth with a pair of grinding wheels that match the set width and set angle of the saw tooth, and moves along the throat of the saw until it comes off the saw tooth. Because of this, the sides of the saw teeth are perfectly parallel when viewed from the front, and are polished so that they have the required chiseled angle when viewed from above, resulting in a smooth and beautiful sawn surface on the workpiece, and excellent quality that does not cause bending. You can easily get a bandsaw.
鋸歯に切込んだ砥石車を歯喉に沿って鋸歯から外れる迄
移動させると、砥石車の各部が平均に鋸歯に当って一律

数がか\らず砥石が長持ちする。When the grinding wheel that has been cut into the saw tooth is moved along the tooth throat until it comes off the saw tooth, each part of the grind wheel hits the saw teeth evenly and wears out uniformly, so there is no need for grinding and grinding of the grind wheel, which saves time and effort. The whetstone will last longer.
特有の効果を奏するものである。It has a unique effect.
