In FIG. 4 (b), the hard particles 1 are bonded to a binder 3 such as resin.
In FIG. 4C, the concave rectangular body 10 is adhered onto the base material 7. The size of the composite abrasive grains 8, 9 and 10 is usually about 1 mmφ. Abrasive grains formed by simply combining the conventional hard particles 1 with the resin 3 have a low degree of bonding and a low grinding ratio, and thus have poor grinding performance.
In the case where this is bonded on the base material 7 with a close gap (A >> B), since there is no chip pocket for taking in and discharging grinding dust, it is difficult to discharge the cutting chips and the clogging occurs early and the grinding is performed. It is difficult to supply the liquid to the grinding point, the grinding resistance is increased, and the sharpness is poor.

[Operation] In the abrasive material according to the present invention, the composite abrasive particles obtained by mixing super-abrasive grains of diamond and cBN of almost the same size with super-hard particles and bonding and forming the mixture with a binder are Since the surroundings of the superabrasive grains are hardened and held strongly by the superhard grains for backup, the bonding strength is high and the superabrasive grain holding power is improved. For this reason, the forced cutting by the superabrasive grains is sufficiently performed, and the grinding ratio and the grinding speed can both be increased by the synergistic action of the superabrasive grains and the superhard particles.
Further, since the cemented carbide particles that reinforce the periphery of the superabrasive grains fall off as the binder is consumed, the cutting edge is rich in autogenous action, there is no problem in maintaining the sharpness, and the grindability is extremely improved. Further, in the composite abrasive grains, superabrasive grains and superhard particles are present in multiple layers, so that the life is greatly improved.

When such composite abrasive grains are bonded and fixed on the base material by a binder, the composite abrasive grains are bonded at intervals of at least 3 to 5 times larger than the particle diameter of the composite abrasive grains. By doing so, the chip pockets are sufficiently formed, whereby an excellent abrasive having improved grindability and sharpness can be easily obtained.

In the grinding process using the abrasive material according to the present invention constructed as described above, the abrasive grains themselves mix the fine particles of the superhard particles 1 and the fine particles of the superabrasive particles 2 and combine them with the binder 3. Since it is a composite abrasive grain formed by mechanically bonding and shaping, the surface shape of the composite abrasive grain is rich in undulations, and co-abrasive grinding of superabrasive grains with high wear resistance of the cutting edge and superhard particles that reinforce and back up them. By the action, it becomes possible to carry out a grinding process with extremely good grindability.

That is, since the super-abrasive grains 2 are firmly held and backed up by the surrounding super-hard grains 1, the super-abrasive grains 2 have a high holding force, and the superabrasive grains forcibly cut into the workpiece. This also improves the grinding speed. In this case, the grinding process is not limited to the superabrasive grain 2 but the superhard grain 1
These synergistic grinding actions significantly enhance the grinding performance. Further, since the fine superabrasive particles 2 are firmly held by the superhard particles 1 and the bonding material 3, they do not drop off and wear, and the grinding ratio can be made extremely large. Further, since both the superabrasive grains 2 and the superhard grains 1 use fine particles having a particle size of 5 μmφ or less, highly accurate grinding can be performed with high efficiency. In addition, super hard particles 1 which intervene around the super abrasive grains 2 to reinforce
Is removed as the binder 3 is consumed, so that the cutting edge is rich in autogenous action, and good sharpness is maintained for a long time. Further, since the superabrasive particles 2 and the superhard particles 1 are present in multiple layers in the composite abrasive particles 4, the life is extremely long.

The effect will not be obtained unless the mixing ratio of the superabrasive grains 2 to the superhard grains 1 is at least 1% or more. In addition to super hard particles 1 and super abrasive grains 2, graphite, WS 2 , MoS 2
It is also possible to mix a lubricant such as the above, and by providing lubricity, it is possible to reduce the frictional resistance and enhance the grindability by the abrasive grains. Then, such a composite abrasive grain 4 is applied to the base material 7
Since it is possible to bond the above with a sufficient space B and to grind these gaps as chip pockets, it is extremely easy to discharge the cutting chips, and clogging does not occur with good grindability. Become. The height H of the composite abrasive grains 4 protruding above the base material 7 is 300 μm at maximum depending on the abrasive grain size.
Since it is φ, preferably 100 μmφ or less, the grinding resistance is also small, and the fine finish polishing with fine particles can be efficiently performed in a state where the sharpness is enhanced.

The base material 7 having a sheet shape, a belt shape or a string shape can be wound around a tool or a pad to be used for grinding wood or plastics. In this case, it is convenient to apply a velcro tape or an adhesive to the back surface of the base material so that winding and sticking can be strengthened. The tool sheet includes a vibration sander with a rectangular pad, a hand sponge pad, a rotary sander with a pad for a disc, a belt sander for a belt, and a lier for a flap. Disc pads of various diameters are used. Further, of course, the composite abrasive grains may be directly adhered to these tools and pads for use. When electricity is applied for metal working to utilize the electrolytic action, metal may be used as the binder, or conductivity may be imparted by mixing metals or mixing metal fibers or carbon fibers. When a band-shaped, string-shaped, or sheet-shaped metal is used as the base material, the bonding strength can be increased by dulling the surface in advance and adhering the abrasive grains. Further, as the base material, a mixture of resin, fiber resin, metal and the like can be used.

Since the composite abrasive grains solidified to a size of about μmφ to 300 μmφ are used, the composite abrasive grains have superabrasive grains dispersed throughout and exhibit high grinding performance, and cemented carbide particles to back up these grains. By virtue of the synergistic effect with the above, the superabrasive grain holding property is strong and the forced incision can be sufficiently performed, and the grinding process with extremely good grindability can be performed. In addition, since the super-hard particles that reinforce the super-abrasive particles fall off as the binder is consumed, the cutting edge is also rich in autogenous action, and good sharpness can be maintained for a long period of time. Also, the ultra-hard particles enable grinding with an extremely long life.
