摘要： PROBLEM TO BE SOLVED: To improve the truing property and the dressing property by using a bond member with a good processability, as well as increasing the holding protpery by compound abrasive grains. SOLUTION: A main abrasive grain 11 which consists of a cubic crystal boron nitride(CBN) or a diamond, and consists of a relatively large grain; and auxiliary abrasive grains 12 which consists of grains smaller than the main abrasive grain 11; are combined by a bond member 15 which consists of a bitrified bond member and the like, so as to form a compound abrasive grain 1. Such compound abrasive grains 1 are held by a bond member 3 which consists of a resinoid bond member. Consequently, the parts of the auxiliary abrasive grains 12 exercise the role of the anchor in the bond member 3, to prevent the early removal of abrasive grains. And the turning property and the dressing property are improved by using this resinoid bond member 3 with a good processability.

摘要： PROBLEM TO BE SOLVED: To set a distribution condition of abrasive grain installed on a grinding wheel base metal in a uniform condition. SOLUTION: Abrasive grain 1 comprising diamond or cubic boron nitride(CBN) is mixed with grain 2 having a roughly similar specific gravity to that of the abrasive grain 1 and a roughly spherical form. Mix of these in a uniform condition is installed on a grinding wheel base metal 6 of metal, and they are temporarily attached to each other by an electroplating means (temporarily attaching plating layer) 3. The grain 2 is removed from that in a temporarily attached condition, and the abrasive grain 1 left is enclosed with metal binding agent 5 comprising a plating means. Metal bond grinding wheel in which a distribution condition of the abrasive grain 1 is uniform can thus be formed or manufactured. A uniform distribution condition of the abrasive grain 1 can be formed, and a uniform abrasive grain interval condition can be provided, thereby grinding oil can be smoothly supplied.

摘要： PURPOSE:To improve substantially antiwear property, sharpness, economy and operability by forming a load concentration portion of a grinding wheel of vitrified bond super grain grinding wheel layer. CONSTITUTION:A strip portion of end edge 21 at the workpiece feeding side (cutting side) of a super grain grinding wheel layer 2 in a grinding tool can be formed of a vitrified bond super grain grinding wheel layer 22 to reduce the wear of this portion and improve the life of the whole grinding wheel. The other portions are formed of a resin bond super grain grinding wheel layer 23 having binder including organic polymer as the base material. Since the vitrified bond super grain grinding wheel layer 22 is thus a part of the whole grinding wheel layer 2 and has a limited narrow width, cracks are not generated in sintering said layer 22 so that the grinding tool provided with a faultless uniform vitrified bond super grain grinding wheel layer is obtained.

摘要： PROBLEM TO BE SOLVED: To provide a proper abrasive grain space, also prevent early fall out of an abrasive grain. SOLUTION: In a vitrified grinding wheel comprising an abrasive grain 1 consisting of super abrasive grain of cubic system boron nitride (CBN) grain or diamond grain and a binding agent 3 binding and holding the abrasive grain 1 to consist of vitrified bond material, inside the binding agent 3, between itself and vitrified bond material forming the binding agent 3, is charged with aggregate 2 composed of chrome oxide (Cr2 O3 ) having good affinity. A grain size of this aggregate 2 is 5 to 50 μm. These grains are accumulated in a condition of a particle group 22 with size thereof having a value about 1/3 or more the brasive grain 1, so as to interpose the particle group 22 thus accumulated in the binding agent 3. In this way, the vitrified grinding wheel ensuring a prescribed abrasive grain space is formed, improvement of grinding efficiency is attained, also by reinforcing the binding agent, early fall out of the abrasive grain is prevented.

摘要： PROBLEM TO BE SOLVED: To improve precision of e shape forming surface of a grinding wheel by a method wherein a distance (y) between abrasive grains arranged in the direction orthogonal to the direction having a specified inclination angle or the direction deviated in a range of a specified angle is increased to a value higher than a distance (x) between abrasive grains arranged in the direction having a specified inclination angle with a shape forming direction. SOLUTION: In an A-zone having a given length A in the peripheral direction, diamond abrasive grains 1 are arranged so that a given distance (x) is provided in the direction (an X-direction) having an inclination angle (a cross angle θ) of a given value, being 45 deg. or less, with a shape forming direction. In this state, an X-direction is the direction different in the direction in a 90 deg. arc, namely, in the Y-direction being the direction orthogonal to the X-direction, the diamond abrasive grains 1 are arranged at intervals of a distance (y). In this case, a relation formula of x

摘要： PURPOSE:To reduce grinding resistance and improve durability by using porous particles as a filler to be contained in the binder of a polishing material consisting of super abrasive grains of diamond particles or cubic system boron nitride particles. CONSTITUTION:In a grinding wheel layer 2 after truing, super abrasive grains 4 of cubic system boron nitride, etc. are retained while porous silicon nitride particles 5 as a filler are dispersed in a vitrified binder 3. And, a chip pocket 6 is formed on a grinding wheel face with a filler 5 the top of which is shattered and filler particle pieces are projected out of this part in a cutting-edge form, and a gas cavity 7 is formed in the vitrified binder 3. Thereby, the grinding resistance of a grinding tool can be reduced while improving durability due to the existence of the chip pockets. Also, grinding resistance at the time of truing can be reduced, greatly facilitating cutting.
