Centres

Headstock and tailstock centres come in a number of different forms:

  • Dead center - A centre that does not rotate; commonly found on the tailstock of a lathe.
  • Half male centre - A dead center that has a portion of the 60 degree cone cut away to allow tool access so that you can turn the end of the part.
  • Live centre - A centre that revolves with the work, for example the ball bearing type tailstock centre.
