Advantages of Thickness Sander
Higher Productivity
Wide belt sander machine are capable of quickly sanding large areas of wood. Using a wide belt sander can Produce more, flatter boards in less time. While portable sander is fine for smaller jobs, but if your woodwork shop needs to sand a lot of boards, wide belt sander is better for you.
Customized Machines According To Production Requirements
Wide belt sander machine are configurable, so they have a lot of options. You can choose to change out the belts to achieve a different finish on the material you are using. After changing the abrasive belt, you can use various grit from fine sandpaper to coarse sandpaper. Finer sandpaper will give you a shinier finish. Changing the abrasive belt also allows you to process hard and soft materials at the same time. For example, some woods are softer than others and require more careful sanding, and the ability to adjust wear will benefit your production.
More Consistent Results
A wide belt sander will give you more consistent results than a portable belt sander. It’s easy to accidentally oversand with hand sander, this can seriously affect productivity in high-volume jobs. Because wide belt sander are not affected by manual handling, it is easier to achieve consistent results. This makes wide belt sander ideal for mass production.
Application of Thickness Sander
The machine is mainly used for solid wood panels, flooring, solid wood panel, brush the surface of groove, wire drawing, natural wood brush, and the wood board, synthetic materials, textures, nap etc..After processing the wood surface has a natural wood grain concavo-convex, main and collateral channels clear, effect of the follow-up processing more prominent.
Mainly used for pseudo-classic embossed floor, drawing the floor, furniture board, surface texture and other decorative plate processing; surface wood veneer processing or sheet; threads wood-plastic board synthesize plate surface (straight) processing etc.

Why Choose a Thickness Sander Instead of a Planer Sander?
While both machines aim for thickness consistency, the Thickness Sander (Wide Belt Sander) offers distinct advantages for finishing and precision that a Planer Sander cannot match. Here is why it might be the better investment for your workshop:
- Superior Surface Quality for Finishing: Unlike a Planer Sander which uses blades that can leave “knife marks” or “tear-outs,” a thickness sander uses abrasive belts to provide a glass-smooth surface ready for staining or painting.
- Safe for Thin and Delicate Materials: Thickness sanders are ideal for processing thin veneers and brittle wood species that would likely shatter or crack under the aggressive impact of a planer’s cutter head.
- Precision and Tight Tolerances: The sanding process allows for micro-adjustments, ensuring that your panels achieve a uniform thickness with much tighter tolerances (down to ±0.1mm) compared to the heavy-duty removal of a planer.
- Reduced Risk of Wood Grain Damage: Planer blades often struggle with figured wood or changing grain directions, leading to surface defects. A wide belt sander grinds the surface evenly regardless of grain orientation.
- Versatile Material Compatibility: Beyond solid wood, a thickness sander is suitable for sanding MDF, plywood, and even some composite materials where a planer would be ineffective or damaging.
- Longer Tool Life for Fine Work: While planer blades dull quickly when hitting glue lines or hard knots, high-quality sanding belts are designed to handle these challenges while maintaining a consistent finish.

FAQ of Thickness Sander
Q1: Which kinds of material is suitable for the ELA-SR-RP650 thickness sander processing?
A1: This kinds of thickness sander includes 650, 1300 and 1600 fro 3 models, which is very suitable for furniture making and woodworking machinery industry, especially processing solid wood panel board, composite board, MDF and wood veneer board. Due to its high RP structure, i.e. roller and padding, it can ensure that different kinds of hardness material wood can get an better and very beautiful surface evenness for flatness.
Q2: Compare with the single roller sanding frame structure, what’s the advantages of this kinds of RP structure?
A2: RP means the first sequence is thicken for fixed height by roller to remove the deviation of panel board, and the second sequence is polished by sanding pad for fine smoothing surface. This kinds of structure shows that once you needs one time pass, it can finish fixed size for thickness and fine sanding two processes so as to improve the working efficiency rapidly.
Q3: What’s the most thin and thick scope can ELA-SR-RP650 thickness sander process?
A3: The processing scope is ranging from 2.5mm to 150mm. So no matter it is for deal with the ultra thin decorative wood veneer laminating for profiling, or the furniture leg material, it can easily be controlled by the PLC controlling system through the adjusting lifting system.
Q4: How to prevent from the burning scar during using process?
A4: It is related with the feeding speed or/and dust collection system. Please ensure that there is the standard 3500m³/h vacuum air system to keep the sanding belt cool. Besides, ELA-SR-RP650 provides 22m/s and 18m/s two kinds of sanding speed, so you can also choose the suitable speed according to your wood material hardness and wood oil content.
Q5: Why there is the requirement for raw material length during feed?
A5: To ensure a stable and safety processing, this machine requires the workpiece shortest length is no less than 400mm. For this is to protect the workpiece can be pressed by the roller for a stable situation from the begin to end during the sanding area, in case of belt jumping or even worn out.
