May 21, 2018#0183;#32;The vertical milling machine is again subdivided 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
the associated maintenance and operational problems. Roller mills are also more sensitive to instantaneous changes in the feed rate than are other pieces of process equipment. Feeding a roller mill directly from a screw conveyor or bucket elevator will cause surges in the feed rate that the roller mill sees instantaneously unless
