摘要： There are disclosed herein a method and an apparatus for manufacturing tubes or tubular bodies by means of hydrostatic extrusion, which tubes or tubular bodies have axially running holes therethrough having cross-sections of irregular shapes. The method and apparatus utilize a mandrel of novel construction which comprises a conical tip portion having a smooth peripheral surface, a cut or grooved intermediate portion with a sloped groove starting at a peripheral edge and a body portion formed with a flange and adapted to move longitudinally of a pressure chamber, as necessary. The conical tip portion is specifically intended to seal against the conical end of a metallic billet. Unless there is such a provision, there would be leakage of a fluid through the grooved portion because of direct contact of the grooved edge with the inner end surface of the billet. Thus, this method and the apparatus for performing the method enables one-step extrusion of tubes or tubular bodies having inner fins or inner walls having irregularly shaped cross-sections, with the accompanying advantages of providing complete sealing among the die, the billet and the mandrel, particularly in the inital stage of the extrusion.

摘要： PURPOSE:To enhance the productivity of a cutting tool whose crystal orientation is selected in its tip section to prolong the life thereof, for machining a disc made of non-ferrous metals or the like with a high degree of accuracy, by inclining the rake face of the cutting tool with a high degree of accuracy. CONSTITUTION:With a diamond cutting tool a rake face Ra is inclined at an angle alpha with respect to the (111) plane A, which is set within a range of 30+ or -5 deg.. That is, since the rake face Ra is inclined at an angle of 25-35 deg., it is inclined sufficiently in the direction of action of its cutting resistance. Further, as to the surface (1-1-1) plane B having a risk of cleavage in relation to cutting, simultaneously with the (111) plane A, since the (1-1-1) plane B is inclined with respect to the (111) plane A, crystallographically at about 70 deg., the inclined angle betawith respect to the rake face Ra is about 155-145 deg.. Thus, the direction of the cutting resistance F is greatly inclined so that it is possible to lower the possibility of occurrence of cleavage.
