Hess Junior single wood sander
---------------------------------

basic structure:

Stable, heavy welded construction made of thick-walled rectangular hollow
profiles
with additional, statically calculated bracing for optimal
vibration damping.

Staggered grinding units with large dimensioned
Belt drive drums for slip-free belt travel. Two-point suction for direct
and airborne dust extraction with integrated blow-off device. grinding units
in heavy steel plate construction as the basis for vibration-damped,
quiet belt run. All guides as a ball linear set on hardened and
polished waves. Lasting precision thanks to protection against dust and dirt
of the sphere linear sets. Contact roller and sanding pad in a balanced ratio
to the grinding belt grain load. The large dimensioned drive drums
guarantee the full transmission of the 5.5 kW drive power of the
grinding motors on the grinding belt. This means the strongest chip removal
possible. Automatic machine stop triggering if the tape breaks. Optical display
on control panel. Sanding shoe for finish made of special material with optimal
Heat dissipation and additional sliding lining. Easy to use
pad change. Abrasive belt tension over appropriately dimensioned
compression springs. Sanding belt relaxation for belt change by means of
pneumatic
Device for sensitive, distortion-free loading of new tapes. Upper
Grinding unit and brush device (additional equipment) centrally motorized
adjustable.

Timber guide in the entry area for hard guide and guide rails supported on both
sides
pinch rollers. Tilt-proof transport of profiled workpieces
calibrated conveyor belts with continuously adjustable
feed rate.

Automatic machine stop triggering by wood thickness control device.
Optical display of the control panel.

Infeed table via fine, precise threaded spindle for lower
Grinding chip removal manually adjustable via scale (resolution 0.1 mm). The
length
Column table guidance guarantees an absolute parallel adjustment. The
Adjustment of the flight circle to the outfeed table is achieved by adjusting
the height of the lower one
Grinding unit via precise threaded spindle and scale display (resolution 0.1
mm) accomplished.

Clear, user-friendly arrangement of all electrical functional, operating
and display elements on the front of the machine: grinding unit below,
Grinding unit above, workpiece transport device,
Grinding thickness setting, brushing device above/below, belt utilization,
Operating display, fault display. All motors are against overload
electrically secured.
