The machining operations generally
carried out in centre lathes are :
- Facing
- Centering
- Rough and finish turning
- Chamfering, shouldering, grooving, recessing etc
- Axial drilling and reaming by holding the cutting tool in the tailstock barrel
- Taper turning by
- offsetting the tailstock
- swivelling the compound slide
- using form tool with taper over short length
- using taper turning attachment if available
- combining longitudinal feed and cross feed, if feasible.
- Boring (internal turning); straight and taper
- Forming; external and internal
- Cutting helical threads; external and internal
- Parting off
- Knurling
In addition to the aforesaid regular
