the hedstock is very important because, in this part, we can fAInd the mein spindol, the change ghiars and the workholding devais the tailstock is a Tul holder òpposit the hedstock the cherrieg holds the tul bit that is muvd by the operator perpendiculary or longitudinally; the bed is linked to hedstock, and alaiGNes carrieg and teilstock, in parallel wey to the exis of spindol.

Different kind of lathe CNC Lathe uses CAM process Turret lathe can performs many machining operations like boring and drilling Multi-spindle lathe can use simultaneously twelve spindles.

Milling

Turret type is also called ''Bridgeport'' and it has small dimensions and versatility, bed type is suitable for mass production the Universal type is a development of the horizontal one and it has a very freedom table and the cutter can be oriented both vertically and horizontally. In vertical one There are turret Type and bed type Insted in horizontal one There are iuniversal TAIp
8
Drilling We can create holes or alter them to specific dimensions we can also bore holes to enlarge them.

The difference among drilling machines is linked to their sizes and their functions radial arm drill is a drill that can be moved away from its column along an arm bench drill is a fixed style of drill, and it is made of a table, base, column, spindle and drill head usually driven By an induction motor.
10
Grinding This process is used to obtain pieces with very good surface
11
surface grinders surface grinders, grind flat surfEISIs and they use table, that, are mUVd forth and back, or rotEItid slowly, as the uil is being lowred ontu the workpis In Centerless grinders the workpiece is muvd and roteitid while it is bing driven egheinst the wheel Centreless grinders internal grinders the workpiece is held by a rotating chuck and muvd egheinst a smoll wheel internal grinders centre type grinders the workpis can be held between two senters and then rotated, these machine are suiteibol for grinding very large parts.
