The demands imposed on the ring when operating on the machine

Index

These are the requirements for a good ring:

  • the best possible raw material as starting material
  • good, but not excessive surface smoothness
  • flat surface
  • precise ring roundness
  • good, uniform surface hardness, higher than that of the traveler
  • perfectly run-in rings (optimum running-in conditions)
  • long service life
  • correct ratio of ring diameter to tube diameter (2:1 to 2.2:1)
  • exact horizontal position
  • exactly centered relative to the spindle.
