CNC grinders have multiple set-ups requiring wheel location repeatability. To hold this constant wheel position, Sopko adapters are ground to a precision BALL LOCATION, which establishes a constant relationship between the adapter taper and wheel face.

We’ll Help You with CNC Grinding!
  • BALL LOCATION for CNC REPEATABILITY.
  • GROUND external threads for SAFETY you can count on.
  • PRECISION internal taper for RELIABLE spindle mounting.
  • CONCENTRIC and SQUARE surfaces for a BETTER WORKPIECE FINISH.
  • BLACK OXIDE finish and completely HEAT TREATED for years of use.
