    • PURPOSE:To realize mass production, by so constituting that a plurality of identical kind works is mounted simultaneously on a machining table of a base unit, drilling processing of the works is performed continuously in order from the same drilling position and replacement of cutting tools is enabled according to a kind of drilling. CONSTITUTION:At the time of working, after works A... have been held on a machining table 2 through chucks 3..., drilling positions of the works A... are positioned simultaneously by moving the machining table 2, to begin with. Then a main spindle 10 of a cutting tool is revolved by a motor 11, a main spindle bracket 9 is lowered by a revolution of a ball screw 32 through a motor 33 for ascent and descent and the main spindle 10 is connected, for example, with a cutting tool holder 15 provided with a cutting tool 14 for forming a prepared hole for reamer hole. The works A... are drilled by the cutting tool 24 simultaneously further by lowering the main spindle bracket 9. Then the cutting tool holder 15 provided with a cutting tool for reaming is divided by controlling a turret plate 13 through a revolution and the reamer hole is finished by a similar action after that.
    • 目的:为了实现批量生产,通过这样构成,将多个相同类型的工件同时安装在基座单元的加工台上,从相同的钻孔位置开始连续地执行工件的钻孔加工,并且更换切削刀具是 根据一种钻孔启用。 规定:在工作时,在加工工作台2上通过夹头3 ...将工件A ...保持在工件A ...的钻孔位置之后,通过移动加工工作台2同时进行开始 用。 然后,切割工具的主轴10由马达11旋转,主轴托架9通过滚珠丝杠32的旋转通过用于上升和下降的马达33而下降,并且主轴10例如连接在主轴10上。 具有设置有用于形成用于扩孔器孔的预定孔的切割工具14的切割工具保持器15。 通过下降主轴支架9同时进一步由切割工具24钻出作品A ...。然后,通过旋转控制转盘13和铰刀来分割设置有用于铰孔的切割工具的切割工具夹具15。 之后,通过类似的动作来完成孔。

    • PURPOSE:To replace a gang head rapidly in a short time by simultaneously interlocking the operations of positioning of the head in a turret and holding of a clamp and the head by the action of cams on the side surface of a transport passage. CONSTITUTION:When cutting work by a gang head is completed, the head is turned by 180 deg., and indexing is performed after the replacement to a new gang head. A turret unit is retreated and positioned at a head changing position, and the rollers 36a and 36b installed onto the both side walls of the gang head roll along cams 14a and 14b, and a shaft 37 is shifted along the direction of axis line, and shafts 48a and 48b are rectilinearly shifted in the direction perpendicular to the shaft 37 by the action of a plate cam 49, and shafts 41 and 43 are turned by the action between the rack of the shaft 37 and the pinion, and a clamp lever 50 is clamped, and the head is positioned and held.
    • 目的:通过同时将头部定位在转台中的操作和通过凸轮在传送通道的侧表面上的作用保持夹子和头部的操作来在短时间内快速地更换组头。 构成:当组合头的切割工作完成时,头部转动180度,更换新组合头后进行分度。 转塔单元退回并位于头部更换位置,并且安装在组头的两个侧壁上的辊36a和36b沿着凸轮14a和14b滚动,并且轴37沿轴线方向移动,并且 轴48a和48b通过板形凸轮49的作用在垂直于轴37的方向上直线偏移,并且轴41和43通过轴37的齿条与小齿轮之间的作用转动,并且夹紧杆50 被夹紧,并且头被定位和保持。
