摘要： PROBLEM TO BE SOLVED: To provide a grinding wheel and a method of manufacturing the grinding wheel in which the arrangement pattern of abrasive grains, a binding agent and pores is always uniform. SOLUTION: A binding agent layer 12 comprising the biding agent 2 is formed on the surface of the abrasive grains 1 and then granulated together with a binder 4 to produce a spherical granulated material 8 with the abrasive grains 1, the binding agent layer 12 and a binder layer 14 formed in concentric spherical structure. The spherical granulated material 8 is put into a rotating die 5 by a conveyor 7 fed at constant speed. At this time, the feed speed of the conveyor 7 and the circumferential speed of the die 5 are synchronized to laminate the spherical granulated material 8 regularly layer by layer. The laminated spherical granulated material 8 is pressurized and sintered to manufacture the grinding wheel.

摘要： PROBLEM TO BE SOLVED: To facilitate temperature control for obtaining favorable wetting with abrasive grains by forming a vitrified bond of crystalline glass and amorphous glass, and taking β wollastonite glass as the crystalline glass. SOLUTION: As a binder, borosilicate glass powder which is amorphous and β wollastonite glass powder mainly composed of Si2 O3 and CaO which is crystalline are mixed at a raio of 7 to 3. A caking additive is added with CBN abrasive grains to the above mixed powder and simultaneously kneaded to be granulated, and a metal mold is filled with granulated material to create a grinding wheel chip 10 through heat baking, and the chip is made adhere to the periphery of a metallic support 11 to manufacture a grinding wheel. The mixing ratio of amorphous glass and crystalline glass is 6:4-8:2. The abrasive grains of baron nitride are bonded by a vitrified bond to make a grinding wheel, so that the bending strength can be improved so as to increase the grade with abrasive grains.

摘要： PROBLEM TO BE SOLVED: To enable even rough finish polishing by dry barrel polishing by sintering a mixed material of argillaceous particulates, abrasive particles and aluminium hydroxide particulates as a small grain shape. SOLUTION: In dry barrel polishing inorganic media by sintering a mixed material of argillaceous particulates and abrasive particles as a binding material, aluminium hydroxide is added to and mixed in the mixed material. By the aluminium hydroxide, the media can be formed not only as a cutting quality maintenance preferential type and but also can be formed as a wear-tear restraint preferential type by adjusting its adding quantity, but when 5wt.% or more is contained, a shape of the media largely collapses by sintering, and since the media having a desired shape is hardly obtained, it is desirable that 5wt.% or less be contained for a general use.

摘要： PURPOSE:To reduce the thermal energy by obtaining the amount of wear of a grinding wheel from the dimensional information from an inlet side dimension detector and an outlet side dimension detector, and providing a wear amount-following controller to move the grinding wheel toward the center in the radial direction of a work according to the wear to grind and remove the surface defect of a slab in the hot condition. CONSTITUTION:When a body of revolution is rotated by a driving device 4, and a surface defect is detected by an inlet side defect detector 8i on a work W moving through a stock passage of an inner cylinder, the grinding wheel is moved by the rotation of a grinding wheel driving device in the direction of the work by the attraction of an electromagnet M by a grinding wheel position controller based on the defect information from the inlet side defect detector 8i after the period of time to be obtained from the distance between the inlet side defect detector 8i and the grinding wheel and the moving speed of the work W, and the surface of the work W is spirally ground. The grinding wheel is worn, the grinding quantity is reduced in comparison with the specified value of the grinding by the inlet side defect detector, and the dimension of the work W is increased. This is detected by an outlet side dimension detector 8o, and a wear-following controller is actuated thereby.

摘要： PURPOSE:To make it possible to lessen the dropout and wear of abrasive grains, prolong the service life of a grindstone, and keep it's grinding ability well by using phosphoric acid or phosphate as abrasive binder. CONSTITUTION:A grindstone whose abrasive grains are strongly bound is obtained by mixing mineral fiber or glass fiber with phosphoric acid or phosphate binder, adding abrasive grains to the mixture, press-forming the resultant and then only drying it without high temperature treatment. As a result the dropout and wear of the abrasive grains are lessened, and the service life is prolonged, which allows the grindstone to keep good grinding ability for a long time.
