Hess Junior single wood sanding machine
--------------------------------
Machine in checking process at the moment!

Basic structure:

Stable, heavy welded construction made of thick-walled rectangular hollow
profiles with additional, statically calculated reinforcements for optimal
Vibration dampening.

Staggered grinding units with large dimensions
Belt drive drums for slip-free belt running. 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 tape running. All guides as a ball linear set on hardened and
polished waves. Permanent precision thanks to dust and dirt protection
the ball linear sets. Contact roller and sanding pad in a balanced ratio
for sanding belt grain load. The large-sized drive drums
guarantee the full transmission of the 5.5 kW drive power
Grinding motors on the sanding belt. This results in the greatest chip removal
possible. Automatic machine stop activation in the event of a belt break.
Optical display
on control panel. Sanding shoe for finish made of special material with optimal
Heat dissipation and additional sliding coating. Easy to handle
Pad change. Sanding belt tension over appropriately sized
Compression springs. Sanding belt relaxation for belt changing using pneumatic
Device for sensitive, distortion-free placement of new tapes. Upper
Grinding unit and brush device (additional equipment) centrally motorized
adjustable.

Wooden guide in the inlet area for hard guide and bearings mounted on both sides
pressure rollers. Tip-proof transport of profiled workpieces
Calibrated conveyor belts with infinitely adjustable
feed rate.

Automatic machine stop triggering by wood thickness control device.
