2 and FIG. 2, 2 is a cylindrical grindstone core,
The grindstone chip 1 is bonded to the outer periphery by an adhesive 11.
Fit the inner diameter of the grindstone core 2 into the boss 4 of the fixed flange 3,
The inner diameter of the movable flange 5 is fitted into the boss 7 of the fixed flange 3 so as to sandwich the grindstone core 2, and the whetstone core 2 is clamped and clamped between the movable flange 5 and the fixed flange 3 by the tightening bolt 6. The fixed flange 3 is taper-fitted to the grindstone shaft 9, and is fixed to the grindstone shaft 9 by a tightening nut 8.

複数本形成する。The fixed flange 3 and the movable flange 5 are made of a material harder than the grindstone core 2, for example, when the grindstone core 2 is S48c (carbon steel), the fixed flange 3 and the movable flange 5 are SCM435 (chrome molybdenum steel), SK-9 (tool steel). ) And further quench the surface. After that, a plurality of grooves 10 are formed in the circumferential direction on the contact surface between the fixed flange 2 and the movable flange 5 with the grindstone core 2 by etching.

る。Next, the operation will be described based on the configuration described above. The grindstone core 2 is fitted to the boss 4 of the fixed flange 3, the movable flange 5 is fitted to the boss 7 of the fixed flange 3 so as to sandwich the grindstone core 2, and the grindstone core 2 is tightened with the tightening bolts 6 to form the flange 3, By tightening with 5, the grindstone core 2 becomes a flange.
Grooves 2 are fixed in cooperation with fixed flanges 3 and movable flanges 5. Next, the fixed flange 3 is taper-fitted to the grindstone shaft 9, and is fixed to the grindstone shaft 9 by the tightening nut 8. Next, when the grindstone shaft 9 is rotated at a high peripheral speed, centrifugal force acts on the whole grindstone core 2. Since the grindstone core 2 is strongly fixed on the contact surface with the fixed flange 3 and the movable flange 5, the flanges 3, 5 of the grindstone core 2 are fixed.
Expansion of the contact portion with the radial direction is suppressed, expansion of the contact portion of the whetstone core 2 with the flanges 3 and 5 is suppressed in the radial direction, and expansion of the entire whetstone core 2 in the radial direction is suppressed. .

防止する。<Effects of the Invention> As described above, according to the present invention, the fixed flange and the movable flange are made of a material harder than the grindstone core, and a plurality of circumferential grooves are formed on the contact surfaces of the fixed flange and the movable flange with the grinding stone core. As a result, when the flange is tightened, the grindstone core is softer than the flange, so the grindstone core bites into the groove of the flange and suppresses the radial expansion of the contact portion of the grindstone core with the flange, thus suppressing the radial direction of the whole grindstone core. The expansion of the grindstone is suppressed and the grindstone tip is prevented from coming off from the grindstone core.
