    • A stopper head for a CNC lathe is provided to absorb an impact and prevent noise by allowing a material fed from a bar feed to a machining chuck to contact the stopper head before the material reaches the chuck. In a stopper head for a CNC lathe, the structure of a piston(7) inserted into a cylinder(2) has a multi-step layer. A linear bearing portion is inserted into a tip end layer having the thinnest diameter. The linear bearing portion has a cylindrical shape and has a through-hole portion at a central portion thereof. A plurality of oil passages are formed on the outer peripheral surface of the through-hole portion. A plurality of ball bearings are formed lengthwise on the inner peripheral surface of the through-hole. A spring is inserted into a middle layer of the piston. A snap ring(12) is inserted into a snap ring groove(4).
    • 提供用于数控车床的止动头,以在材料到达卡盘之前通过允许从料斗供给到加工卡盘的材料接触止动头来吸收冲击并防止噪音。 在用于CNC车床的止动头中,插入到气缸(2)中的活塞(7)的结构具有多级层。 线性轴承部分插入具有最小直径的末端层。 直线轴承部分具有圆柱形形状并且在其中心部分具有通孔部分。 在通孔部的外周面形成有多个油路。 在通孔的内周面上沿长度方向形成多个滚珠轴承。 弹簧插入活塞的中间层。 卡环(12)插入卡环槽(4)中。
