There 3 speeds of feed
(8/14/18) m/min = 32/48/65 ft/min) can be chosen for
optimal quality and quantity of production. The change
is done in rapid manner by means of belts alteration
on 3-steps-pulley. Output
f. i. about 300 broom handles of 1,30 m in length and
25 mm Ø per hour - feed 8 m/min - incl. manual charging.
On request there also a pneumatic magazine (hopper)
can be mounted, which is changeable for the right working
length (better output through sparing the manual charging).
Construction of the machine:
The upper part of the
steady hollow - casting stand contains the bearing of
the changeable cutterhead by means of heavy ball bearings.
The cutterhead consists of a turning bulk with regulable
curvering, which is fitted with 3 eccentric interior
curves. The 3 cutterholders have swingable bearings
for exact regulation of the diameters. By means of the
curve-ring there the right adjusting of the cutters
is arranged automatically - according to a scale for
reading the diameters.
The cutters of half-round
profile are milling simultaneously as scrubbing and
as smoothing knives. They consist of HSS steel for best
working of timbers of various types. The cutter haven't
any slits, because they are fixed by means of screws
and so can be used till there will be only a small rest.
For machining diameters
less than 10 mm there we can deliver fixed cutterheads
The cutterhead - bonnet
prevents the blowing-out of the wooden chips and also
projecting of knives.
The entering guide
is self-centring at 4 sides and has long guiding ledges
and rippled entering rolls (suitable for all diameters),
the drawing guide is also self-centring,. The drawing
rolls are easily changeable and are graduated in nominal
diameters from 10 up to 50 mm (diameter-steps from 5
to 5 mm) and are delivered according to clients request
(inter-sizes, if required for small tolerances).
In the stand there the worm gearing is running in permanent
oil bath. The motor drives the cutterhead-hollow-arbour
as well as the worm gearing over slender V-belts. The
worm gearing transmits the transport motion to the chain
gears and transport rolls.
