摘要： PROBLEM TO BE SOLVED: To provide a multistage reamer which prevents deterioration in the working accuracy of a hole caused by chips produced by cutting of a blade in another stage. SOLUTION: Because the injecting direction of coolant injected from a coolant hole 8b opening on the working surface 6b of a second blade 4b is set opposite to the injecting direction of coolant injected from a coolant hole 8a opening on the working surface 6a of a first blade 4a, the chips produced through cutting of a cutting edge 5b of the second blade 4b can be discharged toward the direction opposite to the tip side by the coolant injected from the coolant hole 8b opening on the working surface 6b of the second blade 4b. Thus, a flaw on a finishing surface caused with the chips, which are produced at cutting of the cutting edge 5b of the second blade 4b and enter into the gap between the adjacent first blade 4a and the finished surface finished by the first blade 4a, can be prevented, securing the required working accuracy of the hole.

摘要： PROBLEM TO BE SOLVED: To obtain a lubricating oil composition for automobile shock absorbers keeping pleasant traveling comfort on running in a wide range of temperatures, exhibiting optimum damping force for long time and capable of continually holding driving stability. SOLUTION: This composition is obtained by compounding (A) a base oil consisting of a mineral oil and/or a synthetic oil with (B) 5.0-20.0 wt.% (based on the total composition) of a distributed polymethacrylate having an average molecular weight of 30,000-60,000 and (C) 0.1-10 wt.% (based on the total composition) of an amine salt of an acid phosphate. Preferably, the kinetic viscosity at 20 deg.C is 20-24 mm2/s, and the Brookfield viscosity at -40 deg.C is 1,500 mPa.s or less.

摘要： PROBLEM TO BE SOLVED: To measure the shape of a shaft having a twisted blade, at a high speeds and highly accurately. SOLUTION: A work 14 is rotated about an axis and registered to a prescribed rotation position, while one end part and the other end part are supported. A stylus of a touch probe 26 is pressed into contact with a surface of the work at this position. A rotation angle of the work, when the stylus is pressed in contact with the work surface, and the position of the touch probe 26 in the axial direction of the work and in a direction perpendicular to the axis are measured. Any of the blade outline of a twisted blade part, position/run out of the longitudinal reference surface of a shaft part, a position/a run out of a step part formed to the shaft part, and position/diameter/width of a groove part formed on the shaft part is obtained, on the basis of the measured values.

摘要： PURPOSE:To carry out hole finishing with high accuracy without being clogged by chips by a rotating tool, grinding works while oscillating the tool at a low frequency from 5Hz to 500Hz, and cutting long and narrow grinding chips which have been cut by hard abrasive grain. CONSTITUTION:The shank 8 of a reamer 6 where hard magnetic abrasive grain is stuck to a cutting edge part 7 is held by a chuck 9 which can rotate and travel in a vertical direction, and a work 1 is placed on the installation surface of a work supporting plate 3 where a tool relief hole 4 is drilled. Next, the hole 2 of the work 1 and the axial center of the reamer 6 are made to meet each other, and the reamer 6 is made to face the hole 2 of the work 1. Then the reamer 6 is rotated at a rotational speed 10m/min to 300m/min to start cutting process, and at the same time, low frequency oscillation is applied to the work 1 with amplitude of 0.1mm to 3.0mm and at frequency from 5Hz to 500Hz in the axial direction of the reamer 6 to finish material with high rigidity.
