Dual Drive Technology™
• Dual Drive Technology™ – a unique patented twin motor arrange-
ment with separate motors for grinding discs and planetary system,
which enables total control of grinding performance.
1. SATELLITE HEADS – GRINDING BY ROTATION
(a) The diamond grinding tools are attached to the satellite heads.
These heads are grinding by rotation, and can be controlled to oper-
ate with variable speed in both directions.
(b) The satellite heads are working together as a planetary system. This
is achieved by rotating the entire planetary head to which the satel-
lites are attached.
2. SATELLITE ROTATION – BELT TRANSMISSION
(a) Rotation to each of the three satellite head shafts is transmitted by a
belt.
(b) The entire planetary head is rotated to achieve a better controlled
grinding process.
(c) The satellite motor shaft is directly driving the belt. The motor can
operate in both directions.
3. PLANETARY ROTATION – SPROCKET TRANSMISSION
(d) The planetary motor power is transmitted by means of a sprocket
on the motor shaft.
(e) The sprocket drives a chain ring, which is fixed to the planetary
head, which will then rotate. The speed can be adjusted to achieve
optimum grinding results.
