摘要： PURPOSE:To enable abrasive grains mixedly contained in a metal bond layer to be uniformly distributed, and also to be constant in density in a carbide abrasive grain edger which is used as a truer truing a grinding wheel for grinding works or as a grinding stone. CONSTITUTION:Adhesives 22 are adhered on the printing plate of a stamp impression 14 furnished with a surface on which irregularities in a given pattern are disposed. The adhesives 22 of the stamp impression 14 is then transferred onto a metal base 34 in a ring shape, so that carbide abrasive grains 5 are thereby bonded onto the adhesives 22 so as to be sintered together with metal powder 40 within a metal mold.

摘要： PURPOSE:To obtain an electro-deposited grinding wheel taking into consideration the adhesion of a grinding wheel shoe and grinding wheel layer and the grinding wheel shoe surface hardening simultaneously. CONSTITUTION:An abrasive grain 4 is held by a nickel bond layer 5 on the surface of a steel-made shoe 1 for an electro-deposited grinding wheel in which nickel is subjected to ion implantation. Nickel is subjected to ion implantation in the steel-made shoe, so the surface thereof is hardened, and no abrasive grain is pushed into the steel made shoe by the grinding pressure, and also the adhesive force of the nickel bond layer and steel-made shoe is increased and the grinding wheel layer is not fallen.

摘要： PURPOSE:To finely crush abrasive grains without their falling, by rotating a disk like roll that a diamond grain is held by a bond or a disk like roll consisting of ceramics of high hardness in the reverse direction each other at the peripheral speed almost equal to the peripheral speed of an electrodeposited grinding wheel, and bringing the electrodeposited grinding wheel and disk like roll into contact each other. CONSTITUTION:An electrodeposited grinding wheel 11 held with a diamond or CBN abrasive grain 14 via an Ni plating 13 on the outer periphery of a core 12 is rotated, the rolls held with the diamond grain via a bond on the outer periphery of the roll or a roll 21 consisting of a high hardness ceramics are rotated in the reverse direction each other with the peripheral speed almost equal to the peripheral speed of the electrodeposited grinding wheel 11. This electrodeposited grinding wheel 11 and roll 21 are approached each other, the abrasive grain 14 is crushed, the grinding resistance at grinding a work can be reduced, and the finishing face roughness of the work is improved.

摘要： PURPOSE:To shorten the time for correcting the shape of a tooling device, by providing with a correcting device for shaping the peripheral surface of said tooling device approximately in a circular shape without eccentricity, bringing the correcting tool of said device into contact with said tooling device. CONSTITUTION:A super abrasive grain grindstone wheel 16 is axially supported by a grinding stone table through a grinding stone shaft 17 and driven by a motor 18 by means of a belt 19 and pulley. Meanwhile, a correcting device 30 is slidably installed on a tooler table in the P direction crossing the tooler shaft 2. Here, a tooling device 21 is mounted on a tooler shaft 22 according to the conventional way and driven rotatingly, then the correcting tool 32 of a correcting device 30 is brought into contact with the peripheral surface 21a of the tooling device 21, thus the peripheral surface 21a is shaped approximately in a circular shape without eccentricity. This time, appropriate material can be selected for the correcting tool 32 as used exclusively for correction, therefore the time for correcting the tooling device 21 can be reduced.

摘要： PURPOSE:To make effective dressing of grinding stone corners which will be the grinding points of the grinding stone for groove grinding or end part grinding. CONSTITUTION:Free abrasive grain of dressing liquid supplied through an upper nozzle 9 between a dressing roll 3 and a grinding stone G in contraposition is held by being received by a shielding plate 11 without immediate escape to a lateral side. Therefore, bond lapping at a corner part of the grinding stone G to form a clearance t1 which is smaller than the size of the free abrasive grain is effectively done, and dressed for a short lapse of time. And, since the lateral side of the grinding stone G covered by the shielding plate 11 has a clearance t2 formed rather larger than the size of the free abrasive grain, the free abrasive grain passes through the lateral side of the grinding stone G without dressing, resulting in giving no change on the size of the groove width at the time of grinding a groove of the work. Besides, for extending the life of the roll 3, if the same width of an escaping groove 14 in contraposition to an escaping groove 13 on the side of the grinding stone G is formed on the side of the roll 3, the life can be multicatively increased.
