摘要： PURPOSE: To improve the strength of a part of a jig except for a cutting blade part by setting the blade tip working quantity of the cutting face, which forms a cutting blade ridge line, larger than the blade tip working quantity of the flank side. CONSTITUTION: A control board 10 is arranged outside of a work 1 so as to three-dimensionally control the working quantity of a barrel polishing to be applied to the work 1. Change rate of the working quantity can be freely set by changing the ratio of the inner diameter of the control board 10 in relation to the minimum circumscribing circle of the work 1. The ratio of the working quantity of the cutting face side 21 and the working quantity of the flank side 22 of the work 1 can be controlled by changing the thickness J of the control board 10 and the thickness D of a spacer 2, and as the thickness J of the control board 10 is increased and as the thickness D of the spacer 2 is increased, the working quantity of the cutting face side 21 is increased. Consequently, working quantity of a nose R part can be reduced than the working quantity of each side, and at the same time, the working quantity A2 , B2 , C2 of the cutting face side 21 can be set larger than the working quantity of the flank side 22.

摘要： PURPOSE: To uniformly and finely mix hydrocarbon of methane series in a slurry and to prevent the occurrence of coarse particles by adding a specified amt. of the hydrocarbon having a specified m.p. to hard powder, mixing and pulverizing them under cooling. CONSTITUTION: Hydrocarbon of methane series having 20-80 deg.C m.p. is added by 0.1-5 pts.wt. to 100 pts.wt. hard powder of stock such as cermet or ceramics and they are mixed and pulverized in lower alcohol while cooling a prepd. slurry to a temp. below the m.p. of the hydrocarbon by >=10 deg.C. The resultant slurry is passed through a >=200-mesh screen. The cooling is carried out, e.g. by circulating temp.-controlled cooling water through a mixer having a jacket system. The melting and recrystallization of the hydrocarbon in the slurry can be prevented, and When the slurry is passed through the screen, the rate of passing is not reduced and blocking is not caused.

摘要： PURPOSE: To prevent the deposition of a hard powder on a mold and to form a green compact excellent in dimensional accuracy by pressing the hard powder filled in a mold and controlling the temp. of the obtained green compact or the mold to be below a reference temp. CONSTITUTION: A hard powder mixed with an appropriate lubricant is filled in a mold consisting of an outer die 1, an upper punch 2 and a lower punch 3, pressed and continuously compacted to obtain a green compact 6. In this pressing method, an IR thermometer 7 and an analyzer 8 are used to measure the temp. of the green compact 6 discharged from the mold or the mold. Further, the measured temp. is compared with the preset reference temp. in a press controller 9, and an outer die driver 4 and an upper punch driver 5 are controlled so that the temp. of the green compact or mold does not exceed the reference temp. Consequently, the lubricant in the hard powder is not softened or liquefied, the hard powder does not deposit on the mold, and the green compact is not burred or chipped.
