S660MW Industrial Wet Finishing Sander
This belt machine is built for busy labs and shops. The cooling system keeps your work cool, clean, and flat while you grind, sand, and polish. You can use it as a finishing sander to smooth gates and edges. It also works as a stone sander for prepping edges on stone and composite materials. People use it for finishing stainless steel projects.
If you want a compact and strong polishing machine with simple controls and serious rigidity, this is a good choice. It is perfect for metal polishing.
- Wet process controls heat and captures swarf, delivering cleaner air and longer belt life during metal polishing and edge blending.
- Tall, rigid frame and cast‑iron work table give you chatter‑free accuracy for a true finishing sander result.
- Flood system and adjustable nozzle focus coolant where you need it—ideal when finishing stainless steel and other heat‑sensitive alloys.
- Quick‑release lever and one‑knob tracking make belt changes fast; spend more time sanding, less time setup.
- Horizontal or vertical operation adapts to your workflow—from platen work to contact‑wheel shaping—so one machine can serve as a precision polishing machine when you need controlled wet grinding.
- Quiet V‑belt drive and magnetic controls increase operator comfort and uptime.
- Made in America
