Distinctive features

• Feed speed 12-20 m/min;
• Shop for edging material;
• Programming of technological interruptions of glue bath heating;
• Individual frequency converter for each working node;
• Lighting in the protective cabin;
• For safety, the machine is equipped with an electronic cab door locking system;
• The lifting/lowering mechanism of the clamping traverse is equipped with an electric drive, which ensures quick and accurate installation to the required thickness of the part;
• The base ruler with a digital counter guarantees a quick and accurate setting of the required removal on the workpiece during milling at the milling unit;
• Pneumatic shutter on the glue roller, prevents it from getting dirty;
• Adjustment of front and rear overhangs from the control panel.
• The machine has two units for applying liquids:

1. The first unit for applying the separating liquid: with the help of 2 nozzles in front of the pre-milling unit (milling) of the workpiece. This is done by applying a special separating liquid, so that the glue residues that come out do not come into contact with the workpiece.
2. The second unit for applying polishing liquid: using 2 nozzles in front of the polishing unit. This is a cleaning fluid. The main task is to remove the anti-adhesive applied at the beginning (separating liquid) and free adhesive residues. And also to give shine to the finished edge of the part.

Design advantages

The bed of the edge banding machine has the form of a rigid box with the necessary stiffening ribs, which guarantees the exact location of all nodes during the entire period of operation.

The machine is controlled using a special remote control equipped with an industrial display with a “Touch screen” system. The on/off icons of units and assemblies on the display are intuitive and do not require special skills to operate the machine.

Possibility of programming technological interruptions of glue bath heating.

The workpiece feed dispenser rod controls the minimum distance between workpieces, preventing damage to machine components during operation.

The two-roll edge feed magazine simplifies and speeds up the process of changing edges and switching to a different thickness, width, color.

The jointing unit is equipped with two high-frequency motors, which ensures high-quality processing of the end face of the material before gluing the edge. Pre-milling copes with the “step” from the scoring saw, chips. The pre-joint joint is equipped with 40 mm high diamond cutters (65 mm optional).

The pressure unit consists of 4 rollers, which are driven by pneumatics, which guarantees an even distribution of forces on the edge during gluing. Of the 4 rollers, 2 rollers have a different cone, which ensures the distribution of the clamping force over the thickness of the part. 2 cylindrical rollers apply pressure throughout the thickness of the part, and 2 conical rollers are concentrated on the lower and upper parts of the part. The powerful pneumatic cylinder of the pre-cutting knife handles the thick edge well.

Upper glue bath with pre-melted glue, capacity 5 litres. Glue is dosed and does not overheat during machine downtime. The viewing window allows you to control the presence of glue. Warm-up time and readiness for work 15 minutes.

The end trimming unit is equipped with two high-frequency electric motors, and the movement of the saw units is carried out along special linear guides. The unit is equipped with an automatic lubrication system for the guides.

The milling unit consists of two high-frequency electric motors equipped with radius cutters, which allow processing edge material with a thickness of 0.4 - 3.0 mm. The part is tracked by two large round cams (on each motor) mounted on a floating assembly, this design prevents scrap during milling. The machine is equipped with two pairs of milling units - 2 roughing units and 2 units for fine milling of overhangs.

The contouring unit (rounds) is equipped with two high-speed motors and successfully runs at a speed of 20 m/min. Four schemes of work are possible.

Radial scraping with two carbide radius knives, which, after milling a 2.0 mm thick edge, remove a thin layer from the milled part of the edge, as a result we get a smooth machined surface.

The direct scraping unit is equipped with two hard-alloy straight knives (adhesive scraper), which carry out edge processing at the joints with the part. This operation removes excess glue and micro-roughness on the seams in the places where the edge is glued to the part.

The grooving milling unit is equipped with a carbide-tipped grooving saw for milling the groove under the back wall. One of three options for positioning the milling unit is possible: for milling a groove from above, below or at the end of the part.

The polishing unit polishes the processed part of the edge. For safety, the unit is equipped with additional protective covers.
