X5036立式铣床价格汉中X5036立式铣床等幅周期振动2012/07/19
铣床在金属切削过程中,即使没有周期性外力的作用,由于系统内部激发及反馈的相互作用,工件和刀具之间常常会发生强烈的振动,称为震颤。震颤属于自激振动的一种。震颤不仅对加工表面粗糙度、加工精度产生不利影响,也产生恶化环境的噪声,而且还会破坏刀具与机床设备,使生产效率下降。因此,山东天河数控装备有限公司长期以来不断研究改善铣床机械加工震颤理论,以求揭示其机理,掌握其规律,从而加以控制。

1.自由振动:由切削力突然变化、冲击引起,一般可迅速衰减,危害小;
2.强迫振动:在外界周期力的作用下产生,维持一定振幅,危害大;
3.自激振动:有系统内部激发反馈产生的周期振动,危害大。

Mechanical processing in the vibration and classification
1freedom vibration: by cutting force, caused by sudden changes, generally can be rapidly decaying, small damage;
2: in the forced vibration of external periodic force generated under the influence, maintain a certain amplitude, harm;
3: a self-excited vibration system of internal excitation feedback generated periodic vibration, great harm.钻床摇臂钻床数控车床
