    • The invention provides a machine tool capable of facilitating a switching between a guide bush mode and a non-guide bush mode. A machine tool 1 comprises a headstock 10 provided with a main spindle 12 for gripping a workpiece W1, a rail 200 extended along a main spindle axis AX1, a first bearing 110 fixed to the headstock 10 and guided on the rail 200, a second bearing 120 fixed to the headstock 10 on the front side of the first bearing 110 and guided on the rail 200, a supporting bed 30 on which a guide bush 32 is removably mounted to slidably support the workpiece W1 on the front side of the main spindle 12, and a guide 40 mounted on the supporting bed 30 to movably support the headstock 10 in a direction of the main spindle axis when the guide bush 32 is removed. The rail 200 provides a larger play on the second bearing 120 when the headstock 10 is supported by the guide 40 than when the headstock 10 is not supported by the guide 40.
    • 本发明提供一种能够容易地切换导套模式和非导套模式的机床。 机床1包括:头架10,其设置有用于夹持工件W1的主轴12;沿主轴轴线AX1延伸的轨道200;第一轴承110,其固定到头架10并在轨道200上被引导;第二轴承 120,其固定在第一轴承110的前侧的主轴台10上,在轨道200上被引导;支承台30,其以能够装卸的方式安装有导向衬套32,以能够滑动地支承主轴12的前侧的工件W1 以及安装在支承台30上的导向件40,以在拆卸导向衬套32时沿着主主轴轴线的方向可移动地支承主轴箱10。 当主轴箱10由导向件40支撑时,轨道200在第二轴承120上提供比当主轴箱10不由导向件40支撑时更大的间隙。

    • The invention provides a machine tool eliminating the need of keeping the removed feed-mechanism-protection cover outside the machine. The machine tool 1 comprises a headstock 10 provided with a main spindle 12 for gripping a workpiece W1; a driving unit 20 provided with a feed mechanism 22 extended along a main spindle axis AX1 to move the headstock 10 in a main spindle axial direction D1; a supporting bed 30 provided with a guide bush 32 in a removable manner, the guide bush 32 slidably supporting the workpiece W1 on the front side of the main spindle 12; a first cover 40 mounted on the headstock 10 to protect a portion of the feed mechanism 22 with respect to the main spindle axial direction D1; and a second cover 50 removably mounted on the headstock 10 on the front side of the first cover 40 to protect another portion of the feed mechanism 22; wherein, the second cover 50 is detachably attached to the first cover 40 when removed from the headstock 10.
    • 本发明提供了一种机床,该机床无需将取出的进给机构保护罩保持在机器外部。 机床1具备:主轴台10,其具有用于把持工件W1的主轴12; 驱动单元20,其具有沿主主轴轴线AX1延伸的主轴机构22,以使主轴箱10沿主主轴轴向D1移动; 支承台30,其以可拆卸的方式设置有导套32,导套32在主轴12的前侧可滑动地支承工件W1; 安装在主轴箱10上以保护进给机构22的一部分相对于主轴轴向方向D1的第一盖40; 以及可移除地安装在第一盖40的前侧上的头架10上的第二盖50,以保护进给机构22的另一部分; 其中,当从主轴箱10移除时,第二盖50可拆卸地附接到第一盖40。
