Basic structure:
Stable, heavy welded construction made of strong-walled rectangular profiles
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 flying dust with sealing brushes and integrated sanding belt blow-off
Device to increase the service life of the sanding belts. Grinding units in
heavy steel plate construction as the basis for vibration-damped,
quiet tape running. Absolutely backlash-free guides as ball linear sets
hardened and ground shafts. Height adjustment of the grinding units
via hardened and ground special linear guides as well as pre-tensioned ones
Guide carriage. Permanent precision thanks to dust and dirt protection
Ball linear sets and guide carriages.
Large-sized pre-grinding rollers as contact rollers. Contact rollers and
Sanding shoes in a balanced ratio to the sanding belt grain load.
The large drive drums guarantee full transmission
the 5.5 kW drive power of the grinding motors on the sanding belt. Therefore
Slip-free, stable running and optimal heat dissipation. This makes it the
strongest
Chip removal possible. Automatic machine stop activation in the event of a belt
break.
Visual display on the control panel and via flashing lights on the machine.
Sanding shoes for finish completely maintenance-free and wear-free made of
oxide ceramic
with optimal heat dissipation.

Grinding belt tension via appropriately sized compression springs.
Sanding belt relaxation for belt changing using a pneumatic device
sensitive, distortion-free placement of new tapes.
Upper grinding unit and brush device centrally motorized
Height adjustable with digital display in the control panel for the motorized
Grinding thickness adjustment.

Brushing and finishing device, for better surface finish, integrated into
the basic machine. Two special brush rollers 150 mm Æ arranged one above the
other
in synchronous function for advance
thrust. Separate height adjustment of the brush rollers on precise
Carriage guides for post-correction of wear. Additional transport roller for
Removal or further transport of the workpiece from the automatic grinding
machine
with the conveyor belt.
