- BED : Base of the machine . all parts are located in it.
- guide ways way be flat and inverted v.
- automatic chip disposal is an advantage in inverted v guide ways and ensures accurate alignment.
- made of Grey cast iron alloyed with nickel or chromium.
2. HEAD STOCK : secured permanently on the inner ways at the left hand end of the bed . it provides multiple speeds.
- lathe speeds are arranged in geometric progressions.
- back gear arrangement is used to provide minimum speeds to the spindle.
- spindle of the HEAD stock is made of carbon or nickel-chrome steel.
3. TAIL STOCK : Located on the inner ways at the right hand end of the bed.
- it supports the other end of the work when job is machined between centers.
- it holds the tool for performing operations like drilling,reaming,tapping,counter boringetc
4. CARRIAGE : it supports, move and control the cutting tool,and consists of
- saddle: H shaped casting and carries cross slide & tool post.
- cross slide : it is used to move the tool in a direction perpendicular to the axis of a lathe.
- compound rest : used for obtaining angular cuts & short tapers.
