摘要： This invention is a structure and process of truing piston cylinders. The structure consists of a main mandrel support means to hold a mandrel member therein including (1) a support base means; (2) a piston cylinder support means mounted on the support base means; and (3) a power supply means connected to the support base means and the piston cylinder support means. The piston cylinder support means includes a stationary headstock and a movable tailstock, both supported on the support base means. The stationary headstock and the movable tailstock are operable to hold a piston cylinder to be trued therebetween plus each having a mandrel receiving member. The power supply means is operable to supply fluid under pressure to the stationary headstock and return fluid to a reservoir tank through the movable tailstock. The mandrel member resembles a miniature barrel member having a main body member; a plurality of spaced sizing ring sections about the main body member; a central fluid channel in the main body member and a plurality of fluid bleed holes leading from the central fluid channel to areas between the sizing ring sections. The diameters of the sizing ring sections progressively diminish from the center to outer ends. The pressure fluid is forced through the main channel and the fluid bleed holes to force the mandrel member the length of the piston cylinder to achieve accurate sizing thereof to a desired constant diameter.The process of truing piston cylinders consists of the steps of (1) holding a piston cylinder to be trued at opposite ends in a fluid sealed manner; (2) placing a mandrel member at one end of the piston cylinder; (3) applying fluid pressure to one of the mandrel member; (4) moving the mandrel member longitudinally of the piston cylinder; and (5) expanding the diameter of the piston cylinder to maximum diameter of the mandrel member.
