What is moving clockwise and counterclockwise of metal polishing machine

What is moving clockwise and counterclockwise of metal polishing machine? Clockwise and counterclockwise rotation refer to the two running directions of the polishing barrel driven by the magnetic base. Clockwise rotation makes magnetic pins roll inward tightly, delivering intensive grinding for tiny burrs and inner corners. Counterclockwise rotation pushes steel needles to spread out evenly, perfect for surface brightening and large flat workpieces. Alternating two directions regularly prevents pins from tangling, balances polishing uniformity, and avoids dead zones where metal parts cannot get fully deburred.
