Double-Sided Shaper and Sander
is based on metalworking machine criteria.
The thick steel base has a singlepiece box-type construction with
internally-fitted structure bars.
The sliding surfaces of the carriage and machining units are milled and
The machining units are composed of a
sturdy lower slide on which the main head is mounted, together with the
motor and tool holder supports. The cutter heads shafts are fitted
on supports (spheroidal cast iron) with contact angle bearings.
These produce the finest quality shaping
finish, even during particularly heavy machining operations.
The carriage, constructed in cast
iron, has deep reinforcement ribbing designed to counteract very flexing
created by the workpiece clamps. The flexing recorded at the
points of maximum stress is only 0.03 mm.
The sliding system used for the carriage
and machining heads
consists of STAR slideways in hardened, polished steel which are
mounted along their entire length on the base; the slideways are aligned
with a max. tolerance of + 1/100 mm.

permit shaping and sanding on two faces of a solid wood workpiece ,
without the need for copy templates. The shapes required are in
fact obtained through interpolation along the axes: workpiece carriage
axis and machining head axis. The use of an CNC with
this type of machine has a number of advantages, the most important
- No need for copy templates.
Costs involved in constructing templates are
weighing more and more heavily in the costs of the finished product.
The use of CNC technology eliminate the need of
physical copy systems, thus avoiding friction problems as well as
problems created by dust between copy bearings and templates.
Consistent reproduction of original shape
The memorized program is not subject to wear and allows
compensation of the diameter of the tool after grinding.
Machining of special shapes
Extremely high production output
due to machining speeds previously of and overall
production increases thanks to very short set-up times.
