at the bottom/top Ø With 2 offset grinding units each (bottom and
top) Ø Grinding units (bottom and top) connected in series
according to the Dressing principle Ø Pre-sanding with coarse
grit (calibrate) Ø Regrinding with fine grit (finish) Ø
Central motorized height adjustment of the lower grinding units Ø
Central motorized and synchronous height adjustment of the entire
upper Grinding and brushing units including the upper transport
units Ø Oscillating sanding belt utilization (during the sanding
process) Ø Absolute power connection thanks to 5.5 KW motors and
large dimensions drive drums Ø Oxide ceramic grinding shoe
for - exact surface geometry - no adjustment work -
permanent dimensional accuracy - completely maintenance and
wear-free 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.
Wooden guide in the inlet area for hard guide
and bearings mounted on both sides pressure rollers. Safe
transport of profiled workpieces on calibrated ones Conveyor belts
with infinitely adjustable feed speed. Automatic machine stop
triggering by wood thickness control device. Visual display on the
control panel and via flashing lights on the machine.
Inlet
table via fine-running, precise threaded spindle for
lower Grinding chip removal via digital display in the control
panel (resolution 0.01 mm) motor adjustable. The long column
table guide guarantees absolute Parallel adjustment. The flight
circle coordination to the exit table is carried out
by Height adjustment of the lower grinding units via precise
threaded spindle Scale display (resolution 0.1
mm).
Oscill setup. Utilization of the sanding belt to
increase service life Sanding belts and improvement of the surface
finish through motorized sanding and brush unit transverse
displacement.
Clear, user-friendly arrangement of all
electrical functions and operating and display elements in the
control panel: Grinding unit below (pre-grinding regrinding),
grinding unit on top, (pre-grinding-regrinding), automatic.
Star- Triangle start control of the grinding motors, belt
utilization oscillation, brushing and finish device (bottom =
top), central height adjustment with digital Dimension display,
height adjustment of the infeed table with digital dimension
display, Operating display, fault display. Stop and G512123
emergency stop button.
2 potential-free contacts for
pre-machine feed stop in the event of a
malfunction. Electrical protection of all motors against
overload
