摘要： PURPOSE: To improve the wear resistance and to stabilize the dressing function by forming the dressing face of a columnar diamond on the face with the largest wear resistance, and embedding the diamond in a dresser body with the angle of tiltation relative to the grinding surface of a grinding wheel so that the surface is the dressing face. CONSTITUTION: The vertical faces of a columnar diamond 1 are the face (111) which are parallel to each other, and the side faces are the faces (211) parallel to the other, and the end face is cut with the angle of about 60 deg. to the longitudinal direction of the column and with the angle of 23 deg. to the perpendicular plane to the side to form the face (111). The columnar diamond is embedded in a dresser body 3 so that the dressing face is the face (111) which is most difficult to wear. As a result, the wear resistance of the dressing face is excellent, the service life of the dresser is improved, and the stability of the dressing function can be increased.

摘要： PURPOSE: To manufacture an Al sintered alloy base with low coefficient of thermal expansion and high Young's modulus by an ordinary sintering method, by using Al as a main part and sintering Si or alloy powder formed by adding more than any one of Fe, Cu, Mg and the like to Si onto the Al. CONSTITUTION: This grinding wheel is a super adrasive rotating grinding wheel of not less than 200mm in diameter, and a base 2 optimum to a large grinding wheel such as a cam grinding wheel whose grinding is carried out at a peripheral speed of more than 60m/s employs an Al as a main part and is manufactured by sintering Si or alloy powder formed by adding more than any one of Fe, Cu, Mg, Mn, Zn, Ni and Cr to Si onto the Al. In this manufacture, after alloy powder is filled into a base-shaped mold at least, it is heated to a temperature within eutectic point temperature ±80 deg.C to be sintered. By fixing a vitrified abrasive grain layer 3 onto the outer peripheral end of the base, the super abrasive grinding wheel is formed.

CONSTITUTION: This grinding wheel is composed of a pedestal 11 and projections 13 for polishing having numerous chips 12. The chips are buried in the projections 13. This burying is accomplished by placing chips 12 in a molding form D, a systhetic resin 13 is filled, the synthetic resin 13 is pressed by a die d, and the projecting amount of the chips 12 from the surface of the synthetic resin layer 13 is set 0.0025mm, for example. This synthetic resin layer 13 is not limited to cover the projections, but also can make into a synthetic resin layer 13 to cover almost all the surface of the pedestal 11. On the synthetic resin layer 13, liquid exhaust grooves 14 are provided adequately. The liquid exhaust grooves 14 are formed between the projecting form of systhetic resin layers 13, for example.

摘要： PURPOSE:To reduce the adhesion of plating and improve molding precision, by constituting the part position of a tool which abuts against electronic member by using base material whose coefficient of thermal expansion is smaller than or equal to a specified value, and forming diamond or a diamond type carbon film on the base material surface by a vapor phase synthesis method. CONSTITUTION:Base material 6 having fixing holes 5 is formed by using material, like Si3N4 material, whose coefficient of thermal expansion is smaller than or equal to 5.5X10 . Diamond or diamond type carbon film is formed on the upper part of the base material which part contains an upper surface 22 turning to an abutting surface, by a vapor phase synthesis method. By constituting the abutting surface of a tool made of material whose adhesion to plating is very low, the adhesion of plating is reduced, and molding precision can be improved.

摘要： PURPOSE:To provide a grinding wheel by which destruction caused by rotatation at high speed can be prevented by reducing stress caused by inertial force of rotation to an abrasive grain layer formed by baking or sintering. CONSTITUTION:An abrasive grain layer 2 is arranged on the outer peripheral surface of a base 1, and this abrasive grain layer 2 is formed of plural segments 3 becoming independent in the circumferential direction by means of slit grooves 4. In this structure, since the slit grooves 4 absorb deformation of the base 1 and mass of the respective segments 3 is small, stress caused by inertial force of rotation can be reduced.
