摘要： PROBLEM TO BE SOLVED: To provide regular uneven streaks in the back relief face of a cutting tool with a cutting tip made from a super abrasive sintered body. SOLUTION: A cutting tip 1 is made by sintering a plurality of sintering material using super abrasive grains made of diamonds or CBN(cubic crystal boron grins) as sintering material. This cutting tip 1 is connected to a shank 2 by a connecting means 3. The cutting face 12 and the back flank 11 of the cutting tip 1 are mirror-finished. A cast rotary disk is attached to the back flank 11, and the back flank 11 is polished by always pouring abrasive power comprising diamond powder with specified particle diameter and olive oil mixed between the cutting face 12 and the back flank 11 from a fixed direction. Through such operation, infinite number of regular and uneven streaks parallel with each other are formed from the back flank 11 to the ridge line of a cutting edge.

摘要： PROBLEM TO BE SOLVED: To heighten the strength of a binder and increase the retaining force of abrasive grains. SOLUTION: Powder of one of titanium (Group 4A in Periodic Table), vanadium (Group 5A) and chromium (Group 6A) is mixed with a powder of a metal belonging to Group 1B, whereto an organic binder is added to prepare a paste- form material. This is applied to a base of metal 6 for a grindstone (grinding wheel), and from above it, abrasive grains 1 consisting of diamond or CBN are attached. The resultant is baked at a certain temp. and subjected to provisional fixation (primary baking process). A paste form mixture prepared by using paste-form material as matrix and filling it with particulates 3 consisting of diamond or CBN is applied to the inside of each pocket 5 produced in the primary baking process. The object obtained is subjected to a secondary baking process at a specified temp. Accordingly the abrasive grains 1 are retained by a binder 4 reinforced by the particulates 3, and precluded from premature fallout.

摘要： PURPOSE: To reinforce the holding force of an abrasive grain by arranging plural small grains around a main abrasive grain. CONSTITUTION: Main abrasive grains 1 having relatively large diameter and composed of diamond or cubic boron nitride(CBN) and assistant abrasive grains 2 smaller than the main abrasive grain 1 are prepared beforehand. The abrasive grains 1, 2 are bonded with a bonding material 3 consisting of an alloy (a soldering material) composed of a group 1B metal of the periodic table (e.g. copper, silver or gold) and a metal selected from among titanium (group 4A element of the periodic table), vanadium (group 5A element of the periodic table) and chromium (group 6A element of the periodic table) to form a composite abrasive grain composed of a main abrasive grain 1 positioned at the center and plural assistant abrasive grains 2 bonded to the surface of the main abrasive grain through the bonding material 3. The assistant abrasive grain 2 plays a role of an anchor in the bonding material to prevent the early falling-off of the main abrasive grain.

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.
