Large surfaces are generally face milled on a vertical milling machine with the workpiece clamped directly to the milling machine table to simplify handling and clamping operations. Angular surfaces can also be face milled on a swivel cutter head milling machine (Figure 8-31).
A vertical milling machine is more suitable for end milling operation. Saw Milling Saw-milling is the operation of producing narrow slots or grooves on a workpiece by using a saw-milling cutter. The saw -milling also performed for complete parting off operation.
Here you can see the vertical slide and the new vise in operation - i.e. milling on the lathe. In order to fit the vise to the top slide, I had to modify the toolpost tightening screw and clamp to clear the vise - now, the screw is attached to the handle, and the nut is in the slide - protruding a bit, but not so much as to interfere with the vise.
Milling Machine Definition: The milling machine is a type of machine which removes the material from the workpiece by feeding the work past a rotating multipoint cutter.The metal removal rate is higher very high as the cutter has a high speed and many cutting edges. It is the most important machine in the tool room as nearly all the operations can be performed on it with high accuracy.
a vertical mill correctly takes more skill and experience than is required for lathe operation because of the additional axis (vertical) and the more varied type of work which can be performed. For those wanting to learn more, we have written a 350-page color book called Tabletop Machining (P/N 5301) that covers the subject in much greater detail.
