बोर्ड और लकड़ी के लिए बेल्ट सैंडर

GUANDIAO CNC GD1300

A high-performance wide belt sanding machine designed for processing wood-based panels, solid wood, plastics and metal. Suitable for both rough sanding and final finishing, ensuring excellent surface quality and stable, repeatable results.

The machine is equipped with two independently controlled sanding belt units, allowing the use of two different grit sizes at the same time. Each belt has individual speed control, which prevents surface scratches, overheating and clogging of the abrasive paper.

The conveyor belt table, combined with precise height adjustment, enables sanding of materials up to 100 mm thick. Thickness adjustment is controlled via a digital control panel, ensuring accuracy and ease of operation.

Each sanding drum features independent speed control via frequency inverters and belt position sensors. These systems prevent belt misalignment and automatically stop the machine if improper belt tracking is detected, protecting both the machine and the workpiece.

The sander includes a central dust extraction system, ready to be connected to industrial dust collectors or vacuum systems via Ø100 mm outlets. In addition, each sanding belt is equipped with a pneumatic belt cleaning system, continuously removing dust during operation.

Abrasive belt replacement is quick and easy – a single clamp release allows the belt to be removed from the machine. The sander is compatible with standard abrasive papers available on the market, joined with adhesive tape. No special or proprietary abrasives are required.
