摘要： PROBLEM TO BE SOLVED: To provide a grinding wheel with extra-abrasive grain and a method of manufacturing this grinding wheel with dimples dotted on the outer peripheral surface and with extra-abrasive grains such as diamond abrasive grains or CBN abrasive grains fixed by electroforming. SOLUTION: A method of manufacturing a grinding wheel with extra-abrasive grain comprises a process of attaching a gel adhesive in a dotted state to a conductive ring-like matrix peripheral wall to form protursions, a process of arranging extra-abrasive grains 6 on the matrix peripheral wall by a filling method, a process of temporarily fixing the extra-abrasive grains to the matrix peripheral wall by electroplating, a process of removing excess extra-abrasive grains not temporarily fixed, a process of covering the extra-abrasive grains with a plated layer 8 until all the extra-abrasive grains are covered with plating so as to fix the extra-abrasive grains, a process of filling a fused alloy 10 between the plated layer 8 and core metal 9 inserted in the center of the matrix, and a process of removing the matrix.

摘要： PROBLEM TO BE SOLVED: To easily apply a grinding wheel, and to maintain high accuracy over a long period by scattering dimples on the surface of a diamond dresser in a range of a specific area rate. SOLUTION: Core metal 9 being a main body of a diamond dresser is inserted into the center of a matrix, and a molten alloy 10 such as a tin alloy is poured between the core metal 9 and an elactrocasting layer 9 to form the diamond dresser integrally formed with the core metal 9. Next, a matrix 1 of graphite is removed by cutting and grinding to complete a diamond rotary dresser. Since a sticking projection adhered/fixed to the matrix wall surface is also simultaneously removed by removing the matrix, the trace is automatically formed as a dimple 12 of the dresser surface. An area rate of the dimple 12 of the diamond dresser surface is set to about 7 to 70%. Since a diamond abrasive grain is not fixed to this dimple 12, the diamond abrasive grain can be saved.

摘要： PURPOSE:To follow the change in the diameter of a work with excellent responsiveness, less number of the parts and simple and inexpensive constitution. CONSTITUTION:A work rest follows the change in the diameter of a work by the elastic force of a leaf spring 44. The work rest is brought into point- contact with the work W by mounting a tip 45 of projecting form on the tip of the leaf spring 44, leading to immediate following to the change in the diameter of the work W.

摘要： PURPOSE:To make a tip of the whole abrasive grain be accurately trued to the specified projection height uniformly even if the projection tip height of abrasive grains from a plating layer on an electrodeposited grinding wheel is ununiformity. CONSTITUTION:As for a truing method of an electrodeposited grinding wheel, first of all, a grinding wheel 2, whose whole circumference of one part in a cross direction on a peripheral surface of a disk 3 is formed as a reference peripheral surface, and attached tight with abrasive grains 51 through a plating layer 52 onto the peripheral surface of the other most part of width, is rotated, and then each tip of detectors 31, 32 relatively positioned as being shifted as far as the specified size L in the radial direction to the peripheral surface of a truing wheel 15, is opposed to a reference peripheral surface of the grinding wheel. In addition, the truing wheel and the grinding wheel are relatively approximated, detecting a contact position between both of then, and making the contact position as a reference position, a peripheral surface of the truing wheel and the reference peripheral surface of the grinding wheel are relatively separated as far as the specified value H in the radial direction, and the truing wheel and the grinding wheel rotating together are relatively displaced in the axial direction, making both peripheral surfaces contact with each other, thus truing takes place.

摘要： PURPOSE:To easily correct the circumferential face and end face of a grinding wheel, by forming a peripheral edge end face of a cup like body with a metal bond layer orthogonal to the inside, outside both surfaces, and a diamond layer embedded in parallel to the inside, outside both surfaces at the peripheral wall part between the inside, outside both surfaces of the metal bond layer. CONSTITUTION:In the case of correcting the circumferential face of a grinding wheel W, the grinding wheel W and grinding wheel correction tool 5 are moved with their relative traffic in the axial direction of the grinding wheel W in the range of the axial length of the grinding wheel W. In the case of the end face of the grinding wheel W being then corrected, the grinding wheel W and correction tool 5 are moved with their relative traffic in the radial direction of the grinding wheel W in the range of the radius of the grinding wheel W. Thus, the whole peripheral face and end face whole face of the grinding wheel W are corrected by the diamond layer 7 of the correction tool 5.

摘要： PURPOSE:To improve the break away strength of a segmental chip, by sticking to at least one part of the side end faces of the segmental chip the reinforcing plate solidified by resin arranging concentrically or spirally of plural wirings of different diameters that the fiber direction of a resin system coincides with the grindstone circumferential direction. CONSTITUTION:The stress in the tangential direction applied on the layer of an adhesive 5 with the centrifugal force at the time when a grondstone is rotat ed at high speed is received by the wiring 7 of a reinforcing plate 6 sticked to the side end face of a segmental chip 2. The wiring 7 disperses the stress with its extension in the peripheral direction because of a resin fiber coinciding with the circumferential direction of the grindstone and improves the break away strength of the segmental chip 2.

摘要： PURPOSE:To strongly join the base layer of a segmental tip to the outer peripheral face of a metal core and to increase safety at high peripheral speed and high load times, by mixing an inorganic fiber with the raw material of a base layer and treating the inorganic fiber mixed on the base layer with its exposition after sintering the base layer and abrasive grain layer with their formation. CONSTITUTION:A base layer raw material and abrasive grains are formed in layers in the specific segmental shape, sintered at the temperature by an ordinary method and made in a segmental tip 2. After this sintering the exposition treatment of the inorganic fiber 6 mixed on the base layer 3 of the segmental tip 2 is performed. The base layer 3 thus treated is exposed at its inorganic fibers numerously on the surface thereof and becomes in the state of the so- called fiber being disclosed. Then, the base layer 3 side is sticked by an adhesive 5 to the outer peripheral face of a core 1 by degreasing the oil sticked with the exposition treatment. The base layer 3 sticked to the outer peripheral face of this core 1 becomes in the shape of the exposed inorganic fiber 6 being imbedded into the layer of the adhesive 5 in addition to the joint face of the base layer 3 itself and the adhesive strength is increased more.
