Said machining device comprises a clamping mechanism (12, 12', 14, 14') for mounting the plasticizing cylinder (20, 20') that is to be machined as well as a machining unit (40, 100) for machining the conical screw-type bore. According to the invention, the clamping mechanism (12, 12', 14, 14') is rotatably driven and is configured for eccentrically accommodating the plasticizing cylinder (20) that is to be machined such that the plasticizing cylinder (20) is made to gyrate in a wobbling manner about the axis of symmetry thereof when the clamping mechanism (12, 12', 14, 14') rotates, the future centerline of the conical bore forming the axis of rotation. The machining unit (40, 100) is provided with a turning chisel (46, 106) which can be linearly moved back and forth in the direction of the axis of rotation.

摘要： A cutting method in which, in cutting an inner circumferential face or an outer circumferential face of a work based on turning of a main shaft around a predetermined position serving as a center, control is enabled to make a cutting velocity constant accurately. To achieve the object, a cutting method is provided for an inner circumferential face or an outer circumferential face of a work, using a cutting tool projecting from a main shaft which turns around a predetermined position serving as a center and for which a turning radius is adjustable, wherein, in the case that a turning angular velocity of the main shaft is represented as ω, a distance from a turning center to a tip of the cutting tool is represented as R, and a cutting velocity of the tip of the cutting tool is set to a constant value C, making the cutting velocity of the cutting tool is made constant by performing control such that ω changes in association with a change in the distance R so that ω = C 2 − R ˙ 2 1 2 / R is formulated (where Ṙ denotes a time differential of the distance R), thus providing an even cut face.

The cutting method allows a summation to the cutting velocity under simple control.
