2か得られないという問題点があった。Incidentally, in both the polishing methods shown in FIGS. 7 and 9 above, the arrangement distribution of abrasive grains is irregular as shown in FIG. 8. As a result, the abrasive grains enter the metal film, which has relatively low hardness.
When polishing the magnetic hesode gap forming surface, differences in strength tend to occur between the metal film and other materials.

As a result, there is no difference in level between the metal film and other materials.

プコア15を得る。An embodiment of the method of polishing a composite material according to the present invention is shown in FIGS. 1 to 6. In order to obtain the magnetic held tip core 15 having the gap length 12 with no step between the magnetic alloy film 10 and the non-magnetic substrate 9 shown in FIG. 6, first, the mesh sheet 1 is placed on the silver disk 2 as shown in FIG. A paste-like diamond abrasive liquid 14 previously attached to the rubber roller 3 is spread onto the upper surface of the sawing machine 2 through the mesh sheet 1. That is, the diamond abrasive liquid 14 passes through the abrasive through holes 13 of the mesh sheet 1 shown in FIG. 5 and is deposited on the silver disc 2. When the mesh sheet 1 is then removed, the paste-like diamond abrasive grains 14 attached to the silver disk 2 are positioned in the through holes 13, so that they are regularly distributed as shown in FIG. For attaching the workpiece, the magnetic head block core 5 before gap formation attached to the jig 4 is placed and polished to obtain the polished magnetic head block core 8 shown in FIG. 3. Thereafter, a butting, welding, and slicing process is performed to obtain a magnetic head chip core 15 with a stable gap length of 12 and no steps due to different materials as shown in FIG.

ある。Discovery B Kuto As explained above, the abrasive grains are applied onto an extremely thin mesh sheet made to match the precision of the abrasive grains, and the abrasive grains are placed evenly and regularly on the surface plate. By preventing this movement, it is possible to obtain a metal-in-gap head or a metal laminated head with a stable gap length, and at the same time, it has the excellent effect of improving the yield of gear and knob length.
