The grinding head is the central working assembly on a planetary floor grinder, housing the rotating disc or satellite arrangement that drives the grinding or polishing tooling against the floor surface. It transfers rotational force from the machine's drive system to the tooling, directly controlling cutting pressure, coverage pattern, and finish quality. When the grinding head is worn, damaged, or incorrectly fitted, it causes uneven tooling wear, poor surface contact, and inconsistent results — restoring it with a genuine OEM unit brings the machine back to its designed operating standard.
