が大ぎく、さらに作業能率が低いといった欠点があった
。Conventionally, the commonly used grinding method using a rotary grindstone is so-called /pass grinding using -1 grindstones, so there is a limit to the depth of cut, and if you increase the grinding pressure to increase the depth of cut, There is a restriction that grinding cannot be done with too large a cut because grinding burn occurs and the grinding wheel becomes severely worn. In addition, since the grinding resistance caused by the grindstone is large and is pulled in the opposite direction to the rotation direction, large machines must be equipped with a device to control this. Grinding must be carried out while restraining the human force from pulling in the opposite direction, resulting in over-voltage work, resulting in high worker fatigue and low work efficiency. .

どによる歪の発生が多いために砥石研削による手入れは
不可能とされ、一般にはやむを得ず高価でかつ消耗の激

ており、コスト高を招いている。Furthermore, when grinding thin steel plates, it is considered impossible to grind them with a whetstone because distortion often occurs due to heat generated by grinding, and it is generally unavoidable to use an endless belt sander, which is expensive and consuming. This has led to higher costs.
さらにまた、従来の７個のみの砥石を使用する場合には
、被研削物の表面にびびりゃ段差が入り易くて、商品価
値を低下させる危険性があるといったように多くの欠点
があった。Furthermore, when only seven conventional grindstones are used, there are many drawbacks, such as the tendency for bumps to form on the surface of the object to be ground, which may reduce the commercial value.
本発明はこのような従来欠点を解消した研削方法を提供

ものである。The present invention aims to provide a grinding method that eliminates these conventional drawbacks, and which uses a grinding unit in which a plurality of rotating grindstones are arranged in series so as to rotate in opposite directions. This is characterized in that the grinding pressure cancels out the tensile resistance in the opposite direction to the rotation generated in each rotating grindstone, and that each rotating grindstone performs grinding with the same pressure.
以下に本発明を実施例により詳細に説明する′。The present invention will be explained in detail below with reference to Examples.

直列より僅かにずらした状態にセットされている。What is shown in FIG. 1 is an example of a grinding unit, and this grinding unit 1 has a main shaft 3 located approximately at the center of the longitudinal side surface of a housing/grinding wheel cover 2 which is open at the bottom and is long in one direction. A disc-shaped rotating grindstone 4.4' is mounted on both sides of the main shaft 3 via a grindstone shaft 5.5'. Furthermore, the rotary grindstones 4.4' are set in a state slightly shifted from being in line, as shown in FIG.

無くして作条性よく研削できる。If the main shaft 3 of the grinding unit 1, which is constructed using two rotating grindstones and each of which rotates in opposite directions, is pressed against the surface to be ground, 1
By performing two-point grinding using the 01 rotating grinding wheels 4 and 4' at the same time pressure, it is possible to perform Wllll/pass double grinding, and since each rotating grinding wheel 4 and 4' only needs to cut by h, each grinding wheel can Since this pressure is halved, wear is significantly reduced, and grinding burn is also halved. Furthermore, the rotary grindstone 4.
4' rotate in opposite directions, the grinding resistance cancels out and eventually becomes zero, so large machines do not require a device to control this, and free grinding reduces operator fatigue and danger. Grinding can be done with good row processing efficiency.

る。In addition, when grinding a large area such as a steel plate, the main shaft 3
If you apply grinding pressure centering on 4. both rotary grindstones.
4' swings up and down to reliably cope with distortion in the longitudinal direction of the steel plate, and distortion in the width direction of the steel plate is dealt with by the horizontal swing function of each rotary grindstone 4.4'. After all, osculation grinding is possible in any direction: front, back, left, or right. Furthermore, conventional grinding with a single whetstone involves grinding seven lines, which tends to cause problems and makes it impossible to clean thin plates; however, with the present invention, multiple whetstones are used to simultaneously grind. Since the generation of distortion is suppressed, it is also possible to clean thin plates, and it can be used as a substitute for endless belts.
さらに、第２図に示すように回転砥石４．４′を直線よ

is not limited to the one set in a straight line as in the above embodiment (see Fig. 3), but the rotating grindstone 4 as shown in Fig. V
．． 4' may be set in different positions so that the inner edges of each side form a line, or they may be set in a straight line in double rows as shown in Figure 5. A finished surface ground using each of these grinding units, which may be set with a double row of rotating grindstones 4.4' and a narrower interval between the grinding wheel shafts 5.5', and a finished surface obtained by the conventional method. When compared with the conventional method, when the grinding wheel moves back and forth, the forward cut is up-cut and the backward cut is down-cut, resulting in clearly different stripes on the finished surface and the disadvantage that the surface roughness is also different. In the present invention, even in the case of reciprocating sidewalling, up-cutting is performed, and grinding can be performed to a finished surface without streaks and a uniform surface roughness.
以下に説明するものはワゴン型手入機への応用例であり

のに比べて同じ振り巾で実に二倍の能率を上げることか
できる。The following is an example of application to a wagon-type polishing machine. By setting the swing width of the main spindle 3 to the grinding width of II 00 m/In
Since it is possible to obtain m/1Tl, the efficiency can be doubled with the same swing width compared to the conventional type where the swing width and grinding width are the same and the maximum is about II 00 m/m.
なお、この研削幅は砥石軸５．５′の距離を調節するこ
とにより調整することができる。Note that this grinding width can be adjusted by adjusting the distance of the grindstone shaft 5.5'.
また、従来型のものは、その構造上円弧状研削になるが
本発明では前記研削抵抗の相殺により直線研削が可能と
なり、長手方向０幅方向の何れにも全面直線研削かでき
る。Further, while the conventional type grinds in an arcuate shape due to its structure, the present invention enables straight-line grinding by offsetting the grinding resistance, and can perform straight-line grinding on the entire surface in both the longitudinal direction and the width direction.

るから、片手で軽く操作かでするものである。Furthermore, in the present invention, the weight of the grinding unit and the motor installed as a drive source becomes the grinding pressure, and since a constant grinding pressure is always applied, there is no unevenness in the finished surface unlike in the conventional case of grinding while applying pressure by hand. It is possible to obtain a uniform finished surface without causing any
Since the grinding resistance is canceled out by rotating the wheels in opposite directions, it can be easily operated with one hand.

である。As described above, the grinding method of the present invention uses a grinding unit F in which a plurality of rotating grindstones are set so as to rotate in opposite directions, and this Taf grinding unit is used to apply grinding pressure in the reverse direction. By canceling out the tensile resistance to zero, / bath double grinding doubles the cutting amount by 8 f, and the grinding heat caused by grinding heat prevents the occurrence of distortion, and the dedicated grinding of each rotary grindstone ensures a uniform finished surface. Obtainable. Furthermore, in addition to extending the life of the whetstone, the cost reduction has been realized due to the significant efficiency improvement of Sakuto. It can be widely adopted in many applications such as loading machines.
