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 most commonly used milling machine is a vertical machine, but there are two main styles: turret mills and bed mills. In both, the cutting tool is mounted vertically. On a turretstyle vertical machining center (VMC), the bed moves while the spindle remains in place. Bed mills have the workpiece slide along the bed.

Size restrictions of a desktop cnc mill. The big advantage with this type of mill over a gantry type mill is the available z axis movement. The disadvantage is usually in the amount of y axis travel, this is reduced due to the design. To get more movement in the y axis, the spindle would have to overhang the table by a longer distance.

Climb milling is when the direction of cut and the way the cutting tool rotates combine to try to "suck" the mill up over (hence it's called "climb" milling) or away from the work. It produces the best surface finish. Here is a diagram showing climb milling versus conventional milling for a number of orientations:

The old Vactra oils are now labelled "Vacuoline". Lathe ways are typically Vactra #2 (old)/ Vacuoline 1409(new). Mills often use the heavier oil because of the vertical waysyou want maximum cling time to those vertical dovetails. The lathe oils are typically ISO 68 weight. My mill uses ISO 220 weight which I think used to be called Vactra #4.
