この発明は、研削砥石と被研削物との圧接における研削

して研削加工することが行われる。Creep feed grinding is a precision surface grinding method performed using the outer peripheral surface of a rotatably supported grindstone. In this creep feed grinding, the depth of cut of the grinding wheel is set to be approximately the same as the grinding amount, and the grinding wheel is pressed against the object to be ground while rotating. This is a method in which the grinding finish is completed by sending the material only once. When forming four parts etc. on the object to be ground by grinding, for example, when grinding grooves 2 on the object 1 as shown in FIG. A grinding part 4 is provided in which a grinding surface 4a along the groove 2 is formed in a shape corresponding to the groove 2, and the grinding part 4 is rotated about a central axis 5 while pressing the grinding surface 4a against the object 1 to be ground for grinding. things are done.

物１の送り速度を早くすることが困難であり生産性が悪
いという問題を有している。By the way, in the above-mentioned grinding process, the grinding wheel is brought into pressure contact with the surface of the workpiece while rotating at high speed, so the surface to be ground 2a is exposed to extremely high temperatures, and the surface layer of the surface to be ground 2a may suffer from grinding burn or grinding. Cracks, etc. are likely to occur. For this reason, grinding is performed while pouring coolant between the grinding wheel and the surface 2a of the object 1 to be ground. However, in the above-mentioned grinding wheel, since the entire grinding surface 4a on the outer periphery of the grinding wheel presses against the surface to be ground 2a of the object to be ground 1 during grinding, the surface to be ground 2a is exposed. There is a problem in that the cooling effect is small because it is difficult to apply heat to 2a. Furthermore, since the grinding resistance is large, it is difficult to increase the feeding speed of the object to be ground 1, resulting in a problem of poor productivity.
この発明は、このような事情に鑑みなされたもので、冷

。The present invention was made in view of the above circumstances, and an object of the present invention is to provide a grinding wheel that hardly causes grinding scorch by improving the cooling effect.

斜した帯状に形成され、かつ上記被研削面と−１−記研
削面との圧接面が上記回転軸に対して平行となるように
形成されているという構成をとる。In order to achieve the above object, the grinding wheel of the present invention is a grinding wheel in which abrasive grains are held by a bonding material, and in which the circumference of the grinding surface of the grinding wheel per one rotation of the grinding wheel relative to the surface to be ground is The grinding surface is formed in a belt shape around the rotation axis and inclined with respect to the rotation axis so that the contact area along the grinding wheel does not change throughout one rotation of the grindstone, and the surface to be ground and the grinding surface described in -1- are in pressure contact with each other. The structure is such that the surface is formed parallel to the rotation axis.

って、砥石寿命も長くなる。That is, in the above-mentioned grinding wheel, the grinding surface is formed in a band shape around the rotating shaft, and this band-shaped grinding surface is inclined with respect to the rotating shaft. Therefore, the grinding point during pressure contact between the grinding wheel and the object to be ground always moves laterally along the axis of rotation of the grinding wheel. As a result, a part of the surface to be ground is always exposed, and the coolant liquid is directly applied to it, so the cooling effect of the exposed surface by the air and the cooling effect of the coolant liquid combine to achieve highly efficient cooling. This makes it possible to effectively prevent the occurrence of grinding burns, etc. In addition to the fact that cooling is performed with high efficiency, the contact area is small, so the grinding resistance is reduced. As a result, it becomes possible to increase the rotational speed of the grindstone, and it also becomes possible to improve the grinding speed. Furthermore, the belt-shaped grinding surface that is inclined with respect to the rotation axis is set so that the contact area along the circumference of the grinding surface per one rotation of the grinding wheel does not change throughout one rotation of the grinding wheel. It wears evenly and does not wear unevenly. Therefore, the life of the grinding wheel is also extended.
つぎに、この発明を実施例にもとづいて詳細に説明する
。Next, the present invention will be explained in detail based on examples.
第１図はこの発明の研削砥石の一実施例を示している。 FIG. 1 shows an embodiment of the grinding wheel of the present invention.

As shown in FIG. 2, the grinding surface 8 is a substantially parallelogram strip in front view inclined with respect to the rotation axis 9, and the surface to be ground 11, which is the surface in pressure contact with the object to be ground 10, rotates. It is formed parallel to the axis 9.

Then, when this is placed in a furnace and sintered, the desired grinding wheel 6 is obtained. In addition, in the above manufacturing method, the types of binder and abrasive grains are appropriately selected in addition to those mentioned above depending on the purpose.

」二を左右に移動させても、どの位置でも同じになる。Grinding using this grinding wheel 6 has the following characteristics. That is, as shown in FIG. 2, when the table (not shown) is moved in a direction perpendicular to the drawing and the workpiece 10 is subjected to creep feed grinding, the cutting point of the grindstone 6 is placed on the ground surface shown in the figure. Starting from point P on the grinding surface 11, the grinding surface 11 is sequentially moved to the left. Moreover, since the grinding surface 8 is formed at an angle with respect to the rotation axis 9 of the grindstone 6, the point P' on the grinding surface 8 of the grindstone 6 is
The rotation of the grinding wheel 6 causes the grinding wheel 6 to rotate and move along the circumference of the side surface 6a. Therefore, point P on the grinding surface 8 of the grindstone 6
゛ comes into contact with the point P of the object to be ground 10 intermittently, and grinding comes to be performed intermittently at that point P°. As shown in FIG. 3, which is a developed view of one rotation of the grinding surface 8, the contact area of the grinding surface 8 with an arbitrary part on the surface to be ground 11 per one rotation of the grinding wheel is a

果が得られるようになる。In this way, since the grinding wheel 6 and the grinding surface 8 are formed in a band shape inclined with respect to the grinding wheel rotation axis 9, when the grinding wheel 6 and the workpiece 10 are brought into pressure contact, the cutting points are sequentially It moves along the side edge 8a or 8b of the grinding surface 8, and by this movement it is possible to make sharp cuts at all times. Moreover,
Since grinding is performed intermittently on each part of the grinding surface 8, heat generation during grinding becomes intermittent, and damage to the grindstone 6 and the object to be ground 10 is reduced. In addition, when coolant is applied to the part to be ground, grinding debris removal efficiency and cooling efficiency were poor in the past, but grinding debris can be efficiently removed and the grinding point can be cooled at the gaps in the intermittent grinding described above. Therefore, grinding progresses smoothly. Furthermore, since the contact area of the grinding surface 8 is equal to any part on the surface to be ground 11,
Grinding surface 8 The grinding load is equalized on each part of the self-moon,
Therefore, the wear of the grinding surface 8 is uniform, and the life of the grindstone 6 can be extended. In addition, since the contact area of the grinding surface 8 is small, the grinding resistance is small and the rotation speed of the grinding wheel 6 is increased.
It becomes possible to In this way, when this grindstone 6 is used, the grinding resistance is reduced and the grinding point constantly moves laterally along the rotation axis direction due to the rotation of the grindstone.
A part of the surface to be ground is always exposed, improving the cooling effect of air and coolant, and preventing damage to the surface layer of the surface to be ground and damage to the grindstone, such as grinding burns. Moreover, as a result, the grinding speed can be increased, and the effect of improving productivity can be obtained.

また、この発明の研削砥石は、第１図に示すような砥石
６の外、第４図および第５図に示すように構成してもよ
い。In addition to the grinding wheel 6 shown in FIG. 1, the grinding wheel of the present invention may be constructed as shown in FIGS. 4 and 5.

By providing this groove portion 14, the coolant liquid enters the groove portion 14 and the cooling effect is further increased, thereby making it possible to further increase the grinding speed. Note that the number of grooves is not limited to two, but may be three to four or more.

る。Further, the grinding wheel 15 shown in FIG. 5 has two grinding surfaces 16a, 1
6b have no contact points and are formed to be inclined in opposite directions when viewed from the front with respect to the rotation axis, so that the front ground surface 16a and the back ground surface 16b appear to cross at their centers. ing. While the grinding surface 8 of the grinding wheel 6 shown in FIG. 1 moves in a zigzag pattern from side to side on the surface to be ground 11, the grinding surfaces 16a and 16b of this grinding wheel 15 always move from one side of the surface to be ground 11 toward the other. It becomes like this. For this reason,
An excellent ground surface with a constant grinding direction can be obtained.

As a result, the point of cut of the grinding wheel relative to the workpiece moves sequentially, causing intermittent heat generation during grinding, suppressing the heat generation, and increasing the cooling effect of the coolant and air, resulting in an excellent process with less damage to the grindstone and workpiece. Grinding is achieved.
