- the diamond grains disposed behind do not effectively contribute to the grinding, and reduce the overall grinding efficiency.
- such a tendency becomes remarkable in a grinding operation of a relatively tacky substance typified by, for example, a peeling operation of an elastic paint film.
- the diamond particles on the disk surface will have uneven wear corresponding to the contribution of the grinding work. As a result, the subsequent reduction in grinding efficiency and the life of the diamond disk are reduced.
- a second object of the present invention is to easily set the position of the diamond particle pieces with respect to the disk surface irrespective of the number and arrangement of the diamond particle pieces fixed to the disk surface.
- An object of the present invention is to provide a diamond disc for grinding.
- a third object of the present invention is to focus on the presence of diamond particles that do not contribute to the grinding work among the diamond particles adhered to the disk surface, It is possible to easily identify the manufacturer of the diamond disk from the external appearance by using the grain pieces, and to provide a diamond disk for grinding which is novel and excellent in design.
- a fourth object of the present invention is to provide a grinding diamond disk that can be used not only for grinding work in a narrow sense on a disk surface but also for other purposes. .
- a diamond disk is a diamond disk for grinding in which a plurality of diamond particles are fixed to the grinding function surface of a disk.

It is characterized by the following.
- the separation distance between the preceding and succeeding diamond particles on the common rotation trajectory is set to be longer than the separation distance between the adjacent diamond particles on the adjacent rotation trajectory. Therefore, in the grinding work on concrete, stone, and the like, a sufficient space is secured between the diamond particles rotating on the common rotation trajectory and preceding and following the diamond particles. As a result, the individual diamond particles effectively contribute to the grinding operation without the rear diamond particles being hidden behind the preceding diamond particle in the rotational direction and causing uneven wear. In addition, since a gap is effectively formed between adjacent diamond grains in the rotation direction, the removal of grinding dust is also performed smoothly.

- the arrangement of the diamond grain fragment group unit A in the portion 1a near the peripheral edge is such that the distance between the diamond particle fragment group unit A is gradually narrowed toward the outer peripheral edge 6 of the disk so that the gap outside the disk is gradually reduced.
- the density of the diamond grains 2 is increased, and the diamond grains 2 are arranged so that the density becomes uniform over the entire circumference.
- the diamond particle group unit A which is spirally arranged from the inner circumference to the outer circumference in the direction opposite to the rotation direction of the diamond disk (see arrow R in Fig. 8), eliminates uneven grinding. For this reason, the diamond particle fragments of the part before and after the diamond particle particle group unit unit A arranged in a spiral are arranged so as to partially overlap with each other on the rotation trajectory, and The diamond particle piece group units A before and after being arranged in a spiral shape are arranged with the direction of the diamond particle piece group unit in the radial direction alternately opposite.
- the diamond grains are continuously arranged in the form of a diamond grain cluster unit A from the portion 1 a near the peripheral edge to the outer periphery on the back surface 8 side.
- the diamond particle pieces 2 fixed to the central portion 1b are positioned in consideration of the appearance.
- the central portion 1b has a plurality of diamond grain pieces 2 except for a part in the radial direction (a portion near the center in this embodiment), and the character 2 is stippled from the front. 7 (or a figure) is fixed so that the diamond grain piece 2 is fixed, and a part (a part near the center in this embodiment) where the character 27 is not drawn in a stippled manner is a peripheral part.
- the diamond particle fragment unit unit A is arranged in the same manner as the shift part 1a.
- the diamond particle pieces 2 are adhered to the portion from the flat ring-shaped disk outer peripheral edge 6 to the outer peripheral portion on the back surface 8 side.
- the outer peripheral portion on the back surface 8 side functions as a kind of rotary blade having a predetermined thickness. This Therefore, if cutting is performed in a narrow sense in such a manner that the disk surface 1A is cut into the surface to be polished at a predetermined angle with the outer peripheral edge 6 of the disk as a tip, a groove is formed. Such tasks and cutting work in a narrow sense can be easily performed. In a normal grinding operation using only the disk surface 1A, the grinding performance is the same as that of a conventional diamond disk.
- the central part 1b is a part where the letters 27 are drawn stippled in the circumferential direction
- the peripheral part 1a is a part where the diamond particle fragment group unit A is functionally arranged. Will be mixed in series in harmony.
- These diamond grain pieces 2 themselves are the same as the peripheral part 1a and the center part 1b, but the total number of the diamond grain pieces is fixed to the center part 1b. Is smaller than the number stuck to the peripheral part 1a.
- the central portion 1b is a location that is less contributive to normal grinding work, and thus contributes to auxiliary grinding.
- the central portion 1b has a lower density and is relatively spacious compared to the dense diamond particle piece group unit A seen in the peripheral portion 1a.
- the stippled letters 27 are easily noticeable.
- the grinding diamond disk according to the present invention configured as described above is useful not only for grinding work, but also functions as a kind of rotary cutting blade to increase the versatility of the grinding diamond disk. I can do it.
- the manufacturer name and model can be seen by stippled characters or figures, which is preferable for the user.
- the portion where the above-mentioned characters or figures are drawn is a portion that is hard to be worn even with the passage of time, and thus can be read even when the diamond disk itself is disposed of. Also, the portion where the characters or figures are drawn has a small number of diamond particles, thereby reducing waste of resources. it can.
- the outer edge of the base 1 of the diamond disk is configured to be flat, and the outer edge is rounded toward the rear.
- a configuration may be adopted in which a protruded round-shaped expanded portion 1D is formed, and the diamond particle pieces 2 are arranged on the outer edge of the base 1 including the expanded portion 1D.
- the arrangement of the diamond particle pieces 2 around the expansion section 1D may be continuous, but may be intermittent as shown in FIG. With such a configuration, a grinding operation in a narrow sense can be performed as a cutting operation in a narrow sense.
- the arrow R indicates the rotation direction of the diamond disk.
- a configuration in which the inflated portion 1D is formed may be a diamond disk dedicated to cutting or groove processing in a narrow sense.
- the entire diamond disk body 1 is flattened. It may be a discoid shape.
- an arrow R indicates the rotation direction of the diamond disk.
- FIGS. 11 to 16 the same reference numerals are given to main components common to or corresponding to FIGS. 1 to 10.
- the diamond according to the present invention includes concrete, stone, and tile. Alternatively, it can be used for grinding various kinds of workpieces, such as peeling off a coating film applied to a steel plate or their surface.
