The sanding units as modular elements

Contact roller unit

Kontaktwalzenaggregat

  • Precise steel roller with vibration-free run for heavy calibration works

  • Surface of the steel roller with spiral embeddings in order to guarantee aggressive attack and good cooling

  • The stock removal depends on the grit of the sanding belt, the feed speed, the power of the drive motor and the quantity of the roller units

  • Heesemann achieves a perfect surface after the calibration by means of contact rollers by one or several following fine sanding units

  • For certain applications rubber rollers in all different shores and different diameters are also available


Cross sanding unit

Querschleifaggregat

  • the sanding belt runs cross against feed direction - so the wood fibres are cut off optimally and cannot raise up again after the lacquering process.

  • Pressure of the sanding belt onto the workpiece is effected by means of a segmented pressure beam with CSD®-System

  • Due to the following cross sanding unit behind a roller unit an important grit graduation is possible


Longitudinal sanding unit

Längsschleifaggregat

  • Longitudinal belt executes a final sanding in grain direction

  • Elastic belt tensioning guarantees a high adaptability of the sanding belt

  • Pressure of the sanding belt onto the workpiece is effected by means of a segmented pressure beam with CSD®-System


Longitudinal sanding unit with pressure segment belt

Längsschleifaggregat mit Drucklamellenband

  • For an optimised finish of the wood and lacquer intermediate sanding the execution of the longitudinal unit with a pressure segment belt on the last longitudinal unit is possible

  • The pressure of the sanding belt only takes place in the area of the segments - consequently an interruption of the sanding belt traces and a harmonious surface quality


Longitudinal sanding unit with CSD Plus double pressure beam

Längsschleifaggregat mit CSD Plus

  • The CSD® Plus double pressure beam ensures a finer sanding surface

  • The CSD® Plus system works with two independents controllable CSD® pressure beams

  • By that it is in fact not possible to replace two successive units with graded sanding belt grits, but for different applications a finer surface is produced.

  • Also the combination of pressure segment belt and CSD Plus double pressure beam for the last longitudinal sanding unit is possible and once again leads to a finer surface


Brush roller units

BürstenwalzenaggregatBürstenwalzenaggregat

  • For the treatment of the surface after the sanding process Heesemann uses brush roller units and offers the following different units:

  • For cleaning: Fibre or horsehair

  • For smoothing: Vlies or Anderlon

  • And also for structuring in order to produce desired structures in the wood

  • For the edge chamfering and the sanding of frame parts with fillings sanding brushes with a large diameter can be used. The mounting is effected in view to the feed direction cross , inclined or adjustable in the angle


Orbital Sander

Schwingschleifer

Especially on frame parts with different grain direction the longitudinal traces of the cross veneered upper and lower parts of the frames have to be minimized. This is done by two orbital sanding units which make the total impression of the frame surface more harmonious.
