Machine Overview

The 630mm 2-Belt and 1-Polishing Wheel Sanding Machine is engineered to handle a variety of surface treatment tasks with high accuracy and efficiency. It is primarily used in industries that require high-quality metal and wood finishing, such as automotive, aerospace, metalworking, and woodworking.

  1. Sanding Belts: The machine utilizes two powerful sanding belts for efficient material removal. The first sanding belt, equipped with 15 kW of power, is typically used for coarse sanding and material removal, while the second belt, powered by 11 kW, provides a finer finish. With the ability to adjust the sanding pressure and speed, the machine can handle a wide range of materials, including steel, aluminum, and wood.

  2. Polishing Wheel: The polishing wheel is designed to provide a smooth and glossy finish after the sanding process. Operating at 11 kW, it delivers fine polishing and deburring, ensuring that the workpieces meet high-quality standards. The integration of the polishing wheel also reduces the need for manual finishing, improving production efficiency.

  3. Precision and Accuracy: With a feed power of up to 2.2 kW, the machine can handle a variety of materials and thicknesses with exceptional precision. The system ensures smooth and consistent processing of the material, reducing defects and enhancing the overall surface quality.

  4. Variable Speed Control: The machine features adjustable settings for both sanding and polishing wheels. This gives the operator full control over the speed, pressure, and other parameters to tailor the process to specific requirements. The oscillating motor also contributes to the even distribution of sanding and polishing action across the material.

  5. Ergonomically Designed Worktable: The sanding machine features a robust worktable that ensures a stable platform for the workpiece. The height and angle of the worktable can be adjusted to optimize the sanding process, ensuring that workpieces are held in the correct position for efficient treatment.

Applications

  • Metal Finishing: This machine is ideal for applications in metalworking, including deburring, polishing, and fine sanding of metal surfaces. It is particularly suitable for automotive parts, aerospace components, and machinery parts where precision and surface finish are critical.

  • Calibration: The 2-belt configuration ensures consistent thickness reduction and surface flattening, making it suitable for calibration tasks in both metalworking and woodworking industries.

  • Woodworking: Though it is optimized for metal, the machine can also be used for sanding wood and other materials, particularly for finishing furniture or cabinet components. The polishing wheel provides an ideal solution for smoothing and enhancing the finish of wood pieces.

  • Aerospace and Automotive Applications: Given the high precision required in these industries, this machine is invaluable for the polishing and deburring of small and large components used in cars, airplanes, and other high-precision machinery.

Benefits

  • Enhanced Efficiency: The combination of two sanding belts and a polishing wheel ensures that the machine can process materials in a more efficient and less time-consuming manner. This significantly reduces production costs and increases throughput.

  • Superior Surface Finish: The fine polishing capabilities of the machine ensure that workpieces not only achieve the desired dimensions but also possess a smooth, high-quality finish. The result is a product that meets both aesthetic and functional requirements.

  • Versatility: This machine is highly versatile, capable of working with a variety of materials including ferrous and non-ferrous metals, wood, plastics, and composites. Whether for rough sanding or fine polishing, it adapts to meet specific finishing needs.

  • Customizable Settings: The adjustable speed, pressure, and oscillation settings enable the machine to be customized for specific tasks, allowing operators to fine-tune the machine to suit their unique production requirements.

  • Reduced Labor Costs: By automating key sanding and polishing tasks, the machine reduces the need for manual labor, allowing businesses to streamline production processes and reduce labor costs.

  • Precision and Reliability: The powerful motors and advanced design ensure that the machine operates reliably with minimal maintenance. The precision of the machine allows for consistent, high-quality results, ensuring that every workpiece meets stringent requirements.
