    • 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.
    • 本发明提供一种切削方法,该切削方法在将以规定位置为中心的主轴的旋转作为中心对工件的内周面或外周面进行切削加工时,能够进行正确的切削速度控制。 为了实现该目的,使用从以预定位置为中心转动的主轴突出的切削工具对工件的内周面或外周面进行切削加工, 其中,在主轴的转动角速度被表示为ω,从转动中心到切削工具的尖端的距离被表示为R,并且切削工具的尖端的切削速度 被设定为恒定值C,通过进行控制,使ω与距离R的变化相关联地变化,从而使切削工具的切削速度恒定,从而形成ω= C2-R·212 / R(其中 Ṙ表示距离R的时间差),从而提供均匀的切割面。

    • A spindle assembly for machining a cast workpiece includes a fixture that provides rotational movement to the workpiece around a fixture axis. A first spindle provides rotational movement to a cutting tool around a first spindle axis and a second spindle provides rotational movement to a second cutting tool around a second spindle axis. The first spindle axis and the second spindle axis are transverse to the fixture axis. The fixture is disposed between the first spindle and the second spindle. The pivotal movement of the fixture provides access to opposite sides of the workpiece to the first spindle and the second spindle enabling the cutting tools to simultaneously cut opposing sides of the workpiece. The first cutting tool and the second cutting tool are replaceable by a third cutting tool and a fourth cutting tool to cut an alternative or different aperture into the workpiece.
    • 用于加工铸造工件的主轴组件包括固定装置,该固定装置围绕固定轴线向工件提供旋转运动。 第一主轴围绕第一主轴轴线向切割工具提供旋转运动,并且第二主轴围绕第二主轴轴线向第二切割工具提供旋转运动。 第一主轴轴线和第二主轴轴线横向于固定轴线。 夹具设置在第一主轴和第二主轴之间。 该夹具的枢转运动提供了到达第一主轴和第二主轴的工件的相对侧的通路,使得切削工具能够同时切割工件的相对侧。 第一切割工具和第二切割工具可由第三切割工具和第四切割工具替换以将替代的或不同的孔切割成工件。
