The vertical milling machine is again sub-divided in two types (a) Bed Mill In bed mills, spindle always moves parallel to its own axis while the table moves perpendicular to the axis of the spindle. (b) Turret Mill In turret mills, spindle is in stationary position and table is moved in such a way that it will always perpendicular and parallel to the axis of the spindle during the cutting ...
newer milling machines or machines with minimal spindle wear. Rigidity is critical when using carbide tools. Carbide end mills may require a premium price over the cobalt end mills, but they can also be run at speeds 2 1/2 times faster than HSS end mills. The choice of tool material depends on the material to be cut as well as on the maximum
Vertical and Horizontal Commu-nication in Formal Organizations Traditional theory holds that communication in organizations should, and does, move vertically throughout the hierarchy, rather than cutting across the lines of authority. In order to test this assumption, interviews were carried out among supervisors in a textile mill. Com-
