SR-7SL-1300 Wood Polishing Sanding Machine 1300mm Wide For Wood Surface Smoothing
Description
Our SR-7SL-1300 industrial wood polishing sanding machine is designed to provide consistent ultra smooth surfaces for solid wood, medium density fiberboard, plywood, and primer panels. This heavy-duty machine is equipped with 7 independent lifting sanding machines and touchscreen controls, replacing manual sanding machines and reducing labor costs. The working width reaches 1300mm, which is very suitable for handling large workpieces, avoiding thickness errors and polishing marks caused by multiple processing, and stabilizing the mass production quality of medium and large woodworking factories.
Features
- Intuitive touch screen control with encoded parameter storage saves frequent processing settings, allowing for quick switching of tasks and reducing operator setup time.
- Seven sand rollers support independent vertical lifting or overall synchronous adjustment, which can adapt to uneven wooden boards, with completely uniform polishing and no missing edges.
- Fully sealed dust-proof and noise reducing structure, equipped with a 12 × 100mm large dust cover, meets environmental requirements, and can keep the workshop clean and low-noise.
- The complete CE certification, combined with the built-in grinding wheel safety cover, can effectively prevent operational injuries and comply with factory safety standards.
- Wide and adjustable working range: maximum width of 1300mm, thickness of 80mm, variable brush speed of 80-450rpm, conveyor speed of 5-20m/min, suitable for various wooden materials.
- Heavy duty integrated steel frame, with a total power of 18.82kw and a total weight of 6000kg, ensuring low vibration and long-term continuous production.
- A stable conveyor feeding system can prevent panel deviation and avoid excessive grinding or workpiece damage during large-scale continuous processing.

Frequent asked questions
Q: What types of wood materials can this SR-7SL-1300 machine process?
A: This polishing machine is suitable for most mainstream wooden boards, including solid wood, medium density fiberboard, plywood, particleboard, veneer, and wood boards coated with primer. It can handle both thin veneers and solid wood up to 80 millimeters thick. You only need to adjust the roller speed and feed rate according to the hardness of the wood to avoid surface burns or excessive polishing, and provide a uniform and smooth surface treatment for all qualified wood workpieces.
Q: How long is the official warranty, and do you provide overseas after-sales support?
A: We provide a standard 1-year factory warranty for the entire machine, covering all main motors and core mechanical parts. Our professional technical team provides remote online guidance for installation, parameter debugging, and daily troubleshooting through WhatsApp or email. If necessary, we can also collaborate with local mechanical service providers for on-site maintenance.
Q: Can each sanding roller work separately, and what benefits does independent lifting bring?
A: All seven sanding rollers not only support overall lifting, but also support independent up and down adjustment. When polishing uneven or micro arc shaped wooden boards, you can lower the specific sanding roller to fit the contour of the workpiece surface, thereby avoiding the problem of insufficient polishing of raised areas or excessive polishing of depressed areas. This flexible design can significantly reduce the rate of defective wood and improve the consistency of wood surface flatness in mass production.
Q: How much production efficiency can this polishing machine improve compared with manual sanding?
A: This automatic wide polishing machine can complete the processing of the entire 1300mm wide plate in seconds. One operator can manage two devices at the same time, which is 3 to 5 times more efficient than traditional manual polishing and significantly reduces labor costs. In addition, constant mechanical pressure ensures a smooth and even surface of the wood, which can reduce the occurrence of non-conforming products caused by uneven manual operation and further save raw material costs.

Three months ago, we purchased the SR-7SL-1300 polishing machine for our cabinet production line. The touch screen memory function saves us a lot of time to switch between different panel processes, and the independent roller lifting solves our long-standing problem of uneven primer polishing. We are very satisfied with the stable operational performance and after-sales technical guidance.
