VERTICAL LATHE WITH DAMPED VIBRATION ABSORBER

The invention relates to a vertical lathe with a damped vibration absorber, which comprises: a ram (5) that having accessory (6, 6') at the free end thereof, the ram (5) being movable between a retracted position and an extended position in which vibrations are produced in at least two main bending directions (D1, D2) of the ram (5); a movable mass (7, 7') disposed in the accessory (6, 6') or in the ram (5); guide means (8, 8') designed to guide the movable mass (7, 7') in at least one of the main bending directions (D1, D2) of the ram (5); and at least one first pair of elastic stops (9, 9')disposed in the main bending direction (D1, D2) of the ram (5), between the movable mass (7, 7') and the accessory (6, 6'), or between the movable mass (7, 7') and the ram (5). 一种具有阻尼的振动吸收器的立式车床，其包括：柱塞(5)，其具有在其自由端上的辅助件(6，6')，柱塞(5)可在缩回位置和伸出位置之间移动，其中在柱塞(5)的至少两个主弯曲方向(D1，D2)上产生振动；布置在辅助件(6，6')或柱塞(5)中的可运动质量块(7，7')；适于沿柱塞(5)的主弯曲方向(D1，D2)中的至少一个方向引导可运动质量块(7，7')的引导装置(8，8')；以及至少第一对弹性止挡件(9，9')，其在柱塞(5)的主弯曲方向(D1，D2)上设置在可运动质量块(7，7')和辅助件(
