• High precision counters;
• The ability to automatically reconfigure the traverse to the size set on the control panel using an encoder has been implemented.
• A locating ruler with a digital counter guarantees quick and accurate setting of the required removal on the part during milling at the jointing unit.
• Individual frequency converter for each working unit;
• Workpiece end heating lamp;
• Lighting in the protective cabin;
• Limit switches on the doors in the protective cabin;
• The workpiece feed dispenser rod prevents damage to machine components during operation;
• A pneumatic curtain on the glued application roller prevents it from becoming dirty;
• Adjustment of front and rear edge overhangs from the control panel;
• Execution according to CE standards.
• The machine has two liquid application units:

1. The first unit for applying the separating liquid: using 2 nozzles in front of the unit for preliminary milling (jointing) of the workpiece. This is when a special release liquid is applied; any remaining glue that protrudes outward does not come into contact with the workpiece.
2. Second unit for applying polishing liquid: using 2 nozzles in front of the polishing unit. This is the cleaning fluid that is applied. The main task is to remove the release agent (release liquid) applied at the beginning and any loose adhesive residues. And also to add shine to the processed edge of the part.

Design advantages

Edge banding of panels with narrow frames and routed panels.

The bed of the edgebanding machine has the shape of a rigid box with the necessary stiffening ribs, which guarantees the exact location of all components throughout the entire service life.

The machine is controlled using an industrial personal computer based on WINDOWS 10 with the Touch screen system. The on/off icons for components and assemblies on the display are intuitive and do not require special skills to operate the machine.

Sensor for edge band roll end warning.

Possibility of programming technological breaks in heating the glue bath.

The minimum width of workpieces to be processed is 30 mm and the minimum thickness is 8 mm.

Premilling unit is equipped with two high-frequency motors, which ensures high-quality processing of the end of the material before gluing the edge. Pre-milling copes with the “step” from the scoring saw and chips. The premilling unit is equipped with diamond cutters with a height of 40 mm (65 mm is an option).

Preheating of the workpiece end for better adhesion.

The pressure unit consists of 5 rollers with scrapers to remove excess glue and are driven by pneumatics, which guarantees uniform distribution of forces on the edge during gluing.

OPTIONAL! PUR adhesive pre-melting station.

The sealed adhesive unit for PUR glue prevents the ingress of moisture from the environment and eliminates subsequent hardening of the glue, which significantly reduces the time for servicing the adhesive unit and the influence of the human factor.

The machine is equipped with a top quick-change glue pot with a 5-liter capacity and a glue pre-melting function. The adhesive is supplied in a controlled manner and does not overheat during machine downtime. A viewing window allows easy monitoring of the glue level. The heating time and readiness for operation are only 15 minutes.

The machine is equipped with automatic pneumatic loading of granular glue . A large 12.5 kg hopper is installed at the bottom of the machine frame, from which, through an air flow, the granules are transported to the upper hopper with pre-melt.

The horizontal facing unit ensures precise processing of edge overhangs at the ends of the workpiece and allows you to reduce the distance between workpieces at a speed of up to 30 m/min. Automatic saw angle adjustment. Maglev movement system.

The milling unit consists of two high-frequency electric motors equipped with diamond radius cutters , which allow processing edge material with a thickness of 0.4 - 3.0 mm. The part is tracked using two large round tracers (on each motor) mounted on a floating unit, this design prevents defects during milling. The first milling unit is equipped with cutters with a radius of 2 mm, the second milling unit is equipped with cutters with a radius of 1 mm. Each milling unit is adjusted to two edge thicknesses and switched from the control panel.

The rounding (contouring) unit is equipped with four high-speed motors and operates successfully at a speed of 26 m/min. The unit is equipped with diamond radius cutters. There are four possible operation schemes for the unit.

The first and second scraping units are equipped with two carbide radius knives, which, after milling the edge, remove a thin layer from the milled part of the edge and remove the kinematic wave, as a result we get a smooth processed surface. At the first unit the knife radius is 2 mm, at the second unit the knife radius is 1 mm. The units are switched on from the machine control panel.

Radius scraping units are equipped with mechanisms for pneumatic adjustment from a remote control to another thickness of edge and a mechanism for dividing edge residues along the length for more efficient removal.

The direct scraping unit is equipped with four carbide straight knives (glue scraper), which process the edges at the joints with the part. This operation removes excess glue and micro-irregularities on the seams where the edge is glued to the part.

A double polishing unit polishes the processed part of the edge; high quality is achieved through an oscillation system driven by pneumatic cylinders. To impart a final shine to the edge, a unit for applying polishing liquid is installed.

High-precision adjustment counter on machine components.

Electronic control system for pneumatic aspiration valves.

The steel clamping beam with V-shaped clamping belt guarantees precise and reliable positioning of the workpiece during all stages of edge processing at a speed of 30 m/min.

Additional pressure rollers guarantee reliable fixation of the workpiece.

The encoder on the mechanism for raising/lowering the clamping beam allows you to automatically position the crossarm to the thickness of the part set on the control panel.

The centralized lubrication unit automatically lubricates the guides of the trimming unit.

Electrical components are made in accordance with CE standards.
