Description

Single wood grinding machine Hess Junior

With inlet roller conveyor 2600 mm and outlet roller conveyor 1600 mm

Basic structure:
Sturdy, heavy welded construction made of thick-walled rectangular hollow
sections
with additional, statically calculated stiffeners for optimal
Vibration damping.

Offset arranged grinding units with large dimensions
Belt drive drums for slip-free belt travel. Two-point suction for
Direct and exhaust dust extraction with integrated blow-off device.
Heavy steel plate grinding units as a basis for
vibration damped, quiet tape running. All guides as ball linear set
on hardened and ground waves. Permanent precision through
Dust and dirt lock of ball lens sets. Contact roller and sanding pad
in balance with the grinding belt grain load. The
large drive drums guarantee full transmission of the
5.5 kW drive power of the grinding motors on the grinding belt. Thereby
strongest chip removal possible. Automatic machine stop triggering at
Bandriß. Optical display on operator panel. Sanding pad for finish off
Special material with optimal heat dissipation and additional
Gleitbelagauflage. Easy handling when changing pads. Sanding belt tension
via appropriately sized compression springs. Sanding belt relaxation for
Band change by means of pneumatic device for sensitive, distortion-free
Laying new ribbons.
Upper grinding unit and brush device (additional equipment) central
adjustable by motor.
Wooden guide in the inlet area for hard, both sides mounted guide and
Pressure rollers. Non-tilting transport of profiled workpieces
calibrated conveyor belts with infinitely adjustable
Feed speed.

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

Infeed table via finely detailed, precise threaded spindle for lower
Abrasive chip removal via scale (resolution 0.1 mm) manually adjustable. The
long pillar table guide guarantees absolute parallel adjustment. The
Circuit tuning to the outlet table is by adjusting the height of the lower
Sanding units 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 machine front: grinding unit below,
Top of the loop unit, workpiece transport unit,
Sanding thickness adjustment, brush direction top / bottom, tape usage,
Operating display, fault indicator. All motors are electric against overload
hedged.
