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 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： PURPOSE:To reduce an amount which has to be ground by the straight part of a grinding wheel and minimize a heat generation amount by connecting plural steps tapered part for rough grinding to the straight part for finish grinding in parallel to a work rotational axis, in the case of the peripheral surface of the grinding wheel for grinding a work. CONSTITUTION:Rough grinding on a work periphery is carried out by the front step tapered part 19B and the rear step tapered part 19A of a grinding wheel 16 and then finish grinding on the work periphery is carried out by a straight part 18. In this case, as the grinding wheel 16 is shifted from the position shown by two dots chain line to the position shown by a full line when the work is rotated by one turn, a place ground by the tapered parts 19A, 19B in the previous one turn has to be ground by the straight part 18 of a dull grinding wheel 16, but the amount of an oblique line part H which has to be ground by the straight part 18 is extremely reduced by the existence of the rear step tapered part 19A with a small taper angle thus a heat generation amount is reduced.

摘要： PURPOSE:To minimize a maximum value of a load acting on a cutting edge tool, and prevent shortening of the tool service life by calculating a notching quantity with every notch corrected from the relationship between adjacent maximum loads among maximum loads in the respective notches and a notching quantity at this time. CONSTITUTION:After a notching start position and a notching quantity of respective notches are determined from a machining allowance quantity of a work W, the work W is installed on a grinder, and grinding work is started according to NC data. That is, a grinding wheel stand is advanced and retreated, and a grinding wheel G notches the work W, and when a notching quantity of the grinding wheel G to the work W reaches D1, notching is carried out up to a notching start position S2 of the second process so that the notching quantity becoms D1 and constant thereafter. Hereafter, though notching of the second to the fourth processes is carried out similarly, in this case, a maximum value of a load with every notch is detected, and a notching quantity to equalize values of maximum loads of respective adjacent notches is calculated with every notch from the relationship between adjacent maximum loads and a notching quantity at this time.

摘要： PURPOSE:To complete the grinding in a short time by providing a control means to move the table so that grinding wheel is relatively moved in the direction of a tapered part when the constant signal of the specified means. CONSTITUTION:A first control means 6 cuts a part of the circumferential surface of a work W with a straight part 2 the constant signal of a specified means 5 is outputted, and then, a second control means 8 grinds the work by moving a table 7 so that a grinding wheel 3 is relatively moved in the direction of a tapered part 1. Then, after a wheel spindle stock 4 is advanced in the radial direction of the work W by the specified amount at the end of the circumferential surface by defining the position of the wheel spindle stock 4 as the reference when the constant signal of the specified menas 5 is outputted by a third control means 9, the table 7 is moved so that the grinding wheel is relatively moved in the direction of the tapered part 1, and grinding is executed. This constitution allows the grinding of the circumferential surface of the work W to be completed only by moving the grinding wheel 3 once along the circumferential surface.

摘要： PURPOSE:To hamper burying of a grinding grain, and to improve cooling effect by forming a grinding grain layer out of a small grain body that is distributed and retained in a matrix, and whose grain size is smaller than that of the grinding grain composed of the same material as the grinding grain, and of a grinding grain that is distributed and retained, being in contact with small grain bodies, in a matrix on the upper surface side of the small grain body. CONSTITUTION:When an electrodeposition grinding stone is used to grind an object to be ground, at the time of grinding, the pressure works on a grinding grain 33, at first works on a matrix 31 by which the grinding grain 33 is held, and finally works on a substrate 1. As the matrix 31 is formed of a hard nickel, movement of the grinding grain 33 in the matrix 31 is small. In the matrix 31 between the grinding grain 33 and the substrate 1, a diamond harder than nickel, or a small grain body 32 composed of cubic system boron nitride, which is harder than the matrix alone of the nickel between the grinding grain 33 and the substrate 1. The grinding grain on which grinding force works is held in the small grain body 32, and the pressure is distributed.
