    The effect of dynamic behavior on surface roughness of

    May 30, 2010 The dynamic behavior of a ball screw under a moving grinding force and the resulting ball screw surface roughness are investigated. The system includes a ball screw, a headstock, a tailstock, a steady rest, a grinding wheel, and a wheel head. Equations of motion of the system are derived through Lagrangian approach combined with global assumed mode method in this study. The

    Effects of the friction coefficient of a barrel on the

    May 31, 2018 We investigated the effect of the friction coefficients of a barrel on the grinding performance of multi-layer ceramic capacitors MLCCs in a planetary ball mill. We formulated the motion equation of the MLCCs, including gravitational force, interactive force due to collisions and the drag force in a planetary ball mill, using the three-dimensional discrete element method.

    Aug 30, 2019 The wear of drop steel ball is related to its impact force. The wear of grinding steel balls is related to the surface area of steel balls. In general, the steel ball in the grinder has both impact and abrasion effects, so the wear is proportional to the n power of the diameter of the steel ball, and the value of n is between 2 and 3.
