Sanding machine is a commonly used working tool in woodworking, which refers to the general term for the tools used for sanding wood. In fact, woodworking sanding machines are divided into three categories: drum type, belt type, and disc type, each of which is suitable for different types of wood.
Disc woodworking sanding machine
The disc type woodworking sanding machine uses sandpaper closely attached to the end face of the rotating disc to sand the workpiece, which can be divided into vertical and horizontal, single disc and double disc. The workpiece is manually or mechanically fed and used for flat sanding, suitable for manufacturing industries such as carriages, furniture, and wood molds.
Drum type woodworking sanding machine
The drum type woodworking sanding machine adopts a drum sanding wood material wrapped with sandcloth, which is available in two types: single roll and multi roll. During processing, the drum can not only rotate but also perform axial reciprocating movement to reduce the surface roughness of the workpiece. Single roll sanding machines often use manual feeding, while multi roll workpieces are fed by pressure rollers, upper and lower feeding rollers, or conveyor belts. This type of sanding machine is suitable for sanding the surface of laminated boards, plywood, particleboard, and fiberboard.
Belt type woodworking sanding machine
The belt type woodworking sanding machine tightens the endless circular sand belt on 2 or 3 pulleys, driving the sand belt to move continuously. One tensioning wheel also makes a small amount of warping, causing the sand belt to move laterally. Sanding machines used for flat machining have fixed or mobile workbenches; The sanding machine used for surface machining utilizes the flexibility of the sanding belt to process workpieces under the pressure of the template. The broadband woodworking sanding machine has the advantages of high efficiency, ensuring processing accuracy, and easy replacement of sand belts. It is suitable for sanding large artificial boards, furniture boards, decorative boards, or painted front and rear boards.
