The Husqvarna PG 680/820 ﬂoor surfacing machines are
designed for wet or dry grinding of marble, terrazzo,
granite and concrete. Their applications range from rough
grinding through to a polished ﬁnish. The machine is
intended for commercial use, for example in hotels,
schools, hospitals, factories, ofﬁces etc.
Planetary head and grinding heads are run with
separate motors, so called Dual Drive Technology™.
This gives the operator fully control of both planetary
head and satellite heads in regards to speed and
direction of rotation.
A triple-head grinder gives more downward pressure
and power to the grinding heads compared to 4-head
machines. It also offers more stable operation over
undulating surfaces than 4-head machines.
Gear-driven planetary head with premium quality belt
for power transmission to the grinding heads.
Industrial strength construction.
Robust steel frame.
Spring steel heads.
