Metal Rolling

The three high rolling mill utilizes the principle of passing the work back and forth to achieve a series of reductions. Unlike the two high reversing mill, the three high mill has three rolls that always spin in the same direction. An elevator mechanism lifts and lowers the work so that it can be passed back and forth through the rolls.

Basic Principles of Refrigeration

May 21, 2007· In refrigeration work, inches Hg (inches of mercury) is used to measure negative pressures, called vacuums. A vacuum is a negative pressure (pressure below zero) and is indicated by the word vacuum, such as, 4.5 inches Hg vacuum (or Hg vac). The principle of a negative pressure is shown in Figure 4:

On Vertical Mills, the 4th Axis is frequently parallel to X or Y, and is laid down. On a Horizontal Mill, the 4th Axis is also parallel to X or Y, but it is standing up. Both methods work great, but the horizontal mill's standing 4th axis frequently has more clearance available since the work is never trapped between the table and the axis.

Introduction to the Mill

Work on a milling machine is most often held in a vise clamped onto the bed. To make features aligned with the edges of the stock, it's neccessary to align the vise with the feed axes of the mill. To do this, mount the vise on the bed and secure it with T-bolts, but only lightly so as to permit adjustment of the orientation of the vise.
