Vertical lathe machine configuration. Vertical lathes can machine components within a diameter range from 1 meter to over 20 meters ( inch). A gantry design with a RAM is the base of the construction. Vertical lathes deliver very high metal cutting efficiency. However, the machine utilization can be a disadvantage, due to tool ...

How do you calculate speed and feed? Speed (RPM) = (Surface Feet per Minute x ) / Diameter of the Tool. Feed Rate = RPM x Chip Load x Number of Teeth. RPM = Of the tool or workpiece. Chip Load = The amount of material removed, per revolution per cutting edge. Number of Teeth = The number of edges, facets, or flutes.

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.
