Vertical 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.

The jet velocity v (m/s) was calculated as v = 2 g H (Santolin et al., 2011), thus assuming that head losses before the turbine are 19% of the total losses are already included in the global efficiency value of 70% for the Turgo turbine. The value 19% is quite high for a standard impulse plant, but it is herein justified due to the very small size of the plant and the partial ...

The strategy was a great success. In addition, Carnegie Steel bought up its sources of raw materials and shipping (in a strategy called vertical integration) and bought out and absorbed its competitors (horizontal integration) to dominate the steel industry. By the 1890s, it was the largest and most profitable steel company in the world.
