25" Woodworking Belt Sander Machine

25" (630mm) is a mostly widely used belt sander. 630mm (25") is the maximum width size of work piece it can process. Customer can choose correct sander size according to work piece length. Regular available sizes are 420mm, 630mm. 1000mm and 1300mm.

What Does Pneumatic System Do In A Sander?

Belt sander is configured with an advanced pneumatic automation system and work with an air compresser. This air compresser produces and supplies compressed air to the system. This system controls and ensures sanding to perform correctly and flexibly.

Main Involved Electrical And Mechanical Parts For This System

--Photoelectrical Switch (or substitute for electronic approach switch).

--Air Compresser produces compressed air.

--Oil Water Seperator to filter impurities of compressed air and lubricant air.

--Electromagnet Valve sends off signal and controls air cylinder.

--Air Cylinder performs certain motion.

1. The Photoelectrical Switch feels motion of the belt and sends signal to the Electromagnet Valve, then Electromagnet Valve supplies air to air cylinder. Air cylinder controls belt to swing at uniform speed.

2. When Conveyor belt touches Mechanical Control Valve, it gives signal to air cylinder, and air cylinder expands, then it will automatically adjust conveyor belt and make it place in the middle, do not off track.

3. Each sanding frame is equipped with a big cylinder. A manual valve controls supply air to the air cylinder to expand belt, which makes install or uninstall sanding belt much more convenient.

4. Optional. For eccentric rollers in case of emergency, Electromagnet Valve receives emergency signal, air cylinder can automatically lift the eccentric roller and avoid sanding belt and work piece to be damaged.

5. Pneumatic braking. After sanding belt off track, it contacts travel limit switch, travel limit switch gives signal to Electromagnet Valve. And Electromagnet Valve brakes the machine and machines stops.

Machine body is made in high quality national standard iron plate and soldiered, heavy, no shaking or moving in running, good stability. With heat treatment conditioning process, eliminate interior stress, not easy to deform and shake during running to guarantee precision. Beam is made in high quality Mn-steel, no breaking, anti bending to ensure sanding rollers work stably. Powder coat finish, bright and clean, paint powder not fall off, no scratch. Marble conveyor table in mirror treatment surface and high temperature aging treatment, no deforming, high precise and stable. Press roller can be adjusted up or down to different position or pressure depending on different wood plate material, which guarantees wood plate in correct direction during sanding.
