How to True and Dress Your Wheel

Truing your Diamond and CBN Wheels

  • Examine wheel flanges and spindle with care, and make sure flange surfaces are flat, clean, smooth, and contain no damage.
  • Check your machine spindle for run-out. Ensure it is less than 0.0002”.
  • Mount your wheel
    • Mark edge being trued with a sharpie marker if desired. The wheel is not true until all marker is removed.
  • Using a brake truing device/brake dresser:
    • Start the diamond wheel at normal RPMs
    • Tap the brake dresser wheel so that it is spinning with the diamond wheel.
    • Bring the 2 wheels together until they touch – make sure the truing wheel is spinning when contact is made.
    • Traverse the truing wheel back and forth at a comfortable speed
    • In-feed no more than 0.0005”/pass
    • Continue until wheel is true
      • Marker will be removed; if any still shows, this is a low spot in the wheel and the wheel is not true.
