ある。2. Description of the Related Art In cylindrical grinding by a grinder, a contact portion between a grindstone (for example, 2,000 m / min or more) rotating at a high speed and a work, that is, a machining portion, is used for cooling or lubrication of grinding heat. Although a grinding fluid (coolant) is supplied, it is inevitable that an air layer that rotates with the grinding wheel is inevitable on the outer peripheral surface of the grinding wheel, and therefore, there is a tendency that it is difficult to supply the grinding fluid to an actual processing portion. .

れることになる。３５はワークである。In order to improve the supply efficiency of the grinding fluid, a so-called winding nozzle is used as disclosed in Japanese Patent Application Laid-Open No. Hei 6-32043, for example. This is achieved by, as shown in FIG. 8, extending a shielding plate 32 at the tip of a nozzle body 31 for supplying a grinding fluid and bringing the shielding plate 32 close to immediately before contacting the grinding stone 33.
It is intended to interrupt the continuity of the air layer 34 formed around the rotating grindstone 33, and as a result,
Since a negative pressure is generated on the downstream side of the shielding plate 32 in the rotation direction of the above, the grinding fluid is wound around the grindstone 33, and the grinding fluid is smoothly supplied to the processing portion on the downstream side. Reference numeral 35 denotes a work.

なるような場合には効果的ではあっても、歯車研削盤の
ように加工部位に凹凸がある場合にはその効果が必ずし
も十分ではない。The above-mentioned winding nozzle has such a shape that a grinding wheel has a perfect cylindrical surface like a cylindrical grinding machine, and a contact portion between the grinding wheel 33 and the work 35 becomes linear. Although effective in such a case, the effect is not always sufficient when there are irregularities in the processing portion such as a gear grinder.

なる。More specifically, as shown in FIG. 9, in a state where one thread-shaped grindstone 36 and the gear 37 are engaged with each other, one rotation of the grindstone 36 corresponds to one rotation of the gear 37.
In the gear grinding in which the grinding is performed while rotating the both synchronously at the ratio of the tooth θ, the contact portion between the grindstone 36 and the processed gear 37 becomes uneven, and at the same time, the screw-shaped groove position always moves. The portion corresponding to the thread groove cannot block the air layer, and the supply of the grinding fluid becomes insufficient.

る（実開平５−６３７６０号公報参照）。On the other hand, as shown in FIG. 10, grinding fluid is injected from grinding fluid supply nozzles 39 and 40 provided on both the upstream side and the downstream side in the grinding wheel rotation direction B with respect to the processing portion of the gear-shaped work 38. At the same time, the grindstone 4 is branched by the grindstone cleaning nozzle 41 branched from the grinding fluid supply nozzle 40 on the downstream side.
A technique has been proposed in which a grinding fluid is sprayed toward the grinding wheel 42 to positively remove chips attached to the grindstone 42 (see Japanese Utility Model Laid-Open No. 5-63760).

Not only is it impossible to shut off the air layer, but also the shielding plate 43 and the plurality of nozzles 3
There is a problem in that the structure is significantly complicated due to the combined use of 9, 40 and 41.

Particularly, even when the processing portion has an uneven shape such as a gear grinding, the periphery of the grinding wheel is not affected by the shape of the grinding wheel. It is an object of the present invention to provide a structure in which an air layer formed is cut off so that a grinding fluid can be stably supplied to a processing portion.

Therefore, it is ideal that the flow velocity when the flow of the grinding fluid collides with the grindstone is larger than the peripheral speed of the grindstone. However, change of machining conditions since it is also expected, considering this point, the pump pressure required grinding fluid for supplying to obtain an ideal flow rate when the P 0, the actual pump pressure 0. if the range of 6P 0 ~1.4P 0 can be achieved for the intended purpose.

流れＦが形成される。Therefore, according to the present embodiment, the air layer 22 is formed around the screw-shaped grindstone 8 rotating at a high speed at the same time as the grinding process is started, while rotating with the grindstone 8. Is done. When the grinding fluid is supplied to the grinding fluid supply nozzle 19, the grinding fluid is simultaneously ejected from the first and second injection ports 20, 21 as described above. At this time, as shown in FIG. 3, the grinding fluid sprayed from each of the circular holes 21a forming the second spray ports 21 spreads laterally immediately after the spraying, and the spray widths overlap each other. As a result, a band-like flow F of the grinding fluid, which is sufficiently larger than the width b of the grindstone 8 like an air curtain, is formed.

冷却および潤滑作用を発揮する。The flow F of the band-shaped grinding fluid collides against the outer peripheral surface of the grinding wheel 8 from the normal direction with respect to the screw-shaped grinding wheel 8 having an uneven surface, and faithfully follows the uneven shape. Thus, the continuity of the air layer 22 around the grindstone 8 is interrupted. Therefore, a negative pressure region is formed on the downstream side of the band-shaped grinding fluid flow F, and the same band-shaped grinding fluid L injected from the first injection port 20 is wound around the outer peripheral surface of the grinding wheel 8. With this, it is smoothly supplied to the machined part and exerts the cooling and lubricating action inherent in the grinding fluid.

併せて抑制される。The high-speed band-like flow F of the grinding fluid formed by the second injection port 21 impinges on the grindstone 8 from its normal direction. It serves to wash out the clogged chips and crushed abrasive grains, and as a result, the occurrence of grinding burn due to clogging of the grindstone 8 is also suppressed.

In order to block 2 by the flow F of the grinding fluid from the second injection port 21, the flow velocity of the grinding fluid must be equal to or greater than the peripheral speed of the grinding wheel 8 itself.

液圧力Ｐａは、一般に研削液供給用のポンプ圧（元圧）
Ｐ０に対しておよそ十分の一程度（Ｐａ＝Ｐ０／１０）
である。The grinding fluid pressure Pa on the outer peripheral surface of the grinding wheel 8 a millimeter (20 mm in FIGS. 1 and 3) away from the second injection port 21 is generally a pump pressure (original pressure) for supplying the grinding fluid.
About ten minutes about flush with the P 0 (Pa = P 0/ 10)
It is.
【００３９】一方、研削液の圧力と流速Ｖとの関係は Ｖ＝（２・ｇ・Ｈ）1/2 ただし、Ｖ：研削液流速（ｍ／ｓ） ｇ：重力加速度（ｍ／ｓ2） Ｈ：研削液圧力水頭（ｍ） である。On the other hand, the relationship between the pressure of the grinding fluid and the flow velocity V is as follows: V = (2 · g · H) 1/2 where V: grinding fluid velocity (m / s) g: gravitational acceleration (m / s 2 ) H: Grinding fluid pressure head (m).

Instead of arranging the circular holes 21a in the previous embodiment, a number of elliptical holes 21b are arranged in a straight line. The second injection port 21 is formed by the provision. More specifically, the major axis of each of the elliptical holes 21 b is set at a predetermined angle α with respect to the axis Q 1 of the grinding fluid supply nozzle 19.
And the ends of the holes 21b, 21b in the major diameter direction substantially adjacent to each other overlap with each other.
