RR4240 Wide Belt Wet Sanding Machine High-Efficiency Metal Surface Grinding & Deburring System
Product Description
RR4240 Wide Belt Wet Sanding Machine
High-Efficiency Metal Surface Grinding & Deburring System
The RR4240 is a high-performance wet wide belt sanding machine designed for precision surface grinding, deburring, and finishing of metal sheets and parts. Equipped with a wide 400mm sanding belt and powerful motor system, this machine is ideal for processing stainless steel, carbon steel, aluminum, copper, and other non-ferrous metals.
The RR5240 Wet Wide-Belt Sander is a high-performance industrial grinding and finishing machine designed for the deburring, slag/dross removal, oxide skin removal, edge rounding, and surface finishing of metal sheets and parts. With a 400mm working width, this machine features two sanding heads working under a water bath system, which provides effective cooling and dust suppression during processing.
This model is especially suitable for heat-sensitive materials like stainless steel, thin metal sheets, aluminum, and mixed metals, preventing deformation and discoloration during grinding or polishing.
✅ Key Features & Advantages
✅ Two High-Powered Sanding Stations: Equipped with two sanding heads, the RR5240 delivers superior deburring and surface conditioning in a single pass.
✅ Water Bath Process: Full water circulation reduces heat, prevents workpiece distortion, and minimizes dust and sparks.
✅ Ideal for Heat-Sensitive Materials: Excellent for processing stainless steel, thin metals, and soft non-ferrous alloys without risk of burning or warping.
✅ Heavy-Duty Industrial Design: Robust frame structure ensures stable and vibration-free operation, improving processing precision.
✅ Consistent Finishing Quality: Achieves uniform surface textures from coarse grinding to fine graining finishes.
✅ Minimal Consumable Cost: Wet grinding reduces abrasive belt wear and extends consumable life.
✅ Optional Magnetic Worktable: Securely holds magnetic materials during processing, allowing for precise handling of small or thin parts.
✅ User-Friendly Operation: Intuitive controls, adjustable conveyor speed, and easy maintenance access reduce labor training requirements.
✅ Machine Functions
Deburring: Efficient removal of burrs left after laser cutting, punching, or shearing processes.
Slag & Dross Removal: Effective in removing slag and dross from plasma or flame-cut components.
Oxide Removal: Strips oxide layers and discoloration from cut edges, improving further processing like welding or painting.
Surface Conditioning: Prepares surfaces for downstream processes such as coating, welding, or assembly.
Edge Rounding: Light edge rounding effect with fine abrasive belts to improve part safety and coating adhesion.
Brushing Finish (Optional): With additional brushing units, the machine can achieve decorative finishes like satin or hairline textures (if required in customized configurations).
