Mill Vibration Phenomena during Cold Rolling Innoval

The simplest type of mill vibration is found in all mills. It is a forced vibration due to roll eccentricity and so occurs at roll rotation frequencies. These frequencies are usually lower than any of the resonant frequencies of the mill stand. Therefore, gauge variation is a result of the stiffness response of the mill and the material on the mill. In some cases, at higher speeds, it is

A Closer Look at Vertical and Horizontal Milling Machines

In vertical mills, the spindle axis is vertically oriented. Milling cutters are held in the spindle and rotate on its axis. Typically the spindle can be extended, or the table raised or lowered to produce the same effect, allowing for plunge cuts and drilling. The two kinds of vertical mills are bed mills and turret mills. Vertical turret mills have a stationary spindle and the table is moved
