The milling machine removes metal with a revolving cutting tool called a milling cutter. With various attachments, milling machines can be used for boring, slotting, circular milling dividing, and drilling. This machine can also be used for cutting keyways, racks and gears and for fluting taps and reamers. b. Types.
Read: Understanding lathe machine. Milling head: The milling head is the upper part of a vertical mill machine. It consists of spindle, driving motor and other controlling mechanisms. Ram: The milling machine part can move transversely (in and out) on the column by a hand level.
The machine has only a hand feed mechanism for feeding the tool into the work piece. This enables the operator to feel how the drill is cutting and accordingly he can control the down feed pressure. Sensitive drill presses are manufactured in bench or floor models, i.e., the base of machine may be mounted on a bench or floor. The main operating ...
