Long Belt Sander Best in Sanding

The basic construction of this machine is a worktable, a sanding belt and a sanding shoe. The workpeice is placed on the work table, which is generally adjustable both lengthwise and along its width. The sanding paper, which runs over rollers, is pushed onto the material using a sanding shoe. The surface quality is determined through the choice and texture of the sanding material, and the speed of the sanding belt. The pressure of the sanding shoe is adjusted via a lever and plays an important roll in the surface quality of the end product. The other possibility is to press down the sanding belt using a pneumatically-controlled sanding shoe. This ensures a constant pressure and is best used for continuous high surface quality. Modern machines are fully automatic. This includes guiding the workpiece and controlling the pressure and rotation speed of the sanding belt on the material and the area that is to be sanded. For semi-automatic machines, the sanding shoe has to be manually pressed onto the sanding belt and pulled over the length and width of the workpiece. A measuring device or visual examination is used to check when the material has reached its desired surface quality. Once the desired results have been reached, if it is determined that more work needs to be done, then this process needs to be repeated. Very course sanding paper is used for processing metal surfaces. This process is used, for example, to remove welded seams and then to ensure that the surface is uniformly course. Metal has a higher heat resistance than wood, and so the sanding belt machine can be used at a higher speed. Large safety precautions are not needed on these machines because there are no components that pose a high level of risk. However, an emergency switch is installed onto a long belt sander to stop the machine in the case of an emergency.

Working efficiently with a belt sander

There are many possibilities for sanding, polishing or shaping surfaces, and just as many tools and machines available to undertake these processes. Hand tools are not suited for industrial production, because large workpiece surfaces cannot be processed quickly or accurately enough. Long belt sanders are great machines for woodworking and metalworking facilities because the sanding belt and sanding shoe can be quickly and easily replaced. It is also efficient and affordable for industrial production. Because the construction of a belt sander machine is very minimal, there are rarely components that get worn out. However, the sanding belt and beld disc sander need to be regularly replaced in order to achieve the the desired results.

Manufacturers of belt sanders

New industrial belt sanders are difficult to obtain because the production of these machines has decreased, even though they are required in a lot of different facilities. Manufactures of used belt sanding machine are JOHANNSEN, HÖFER, WINTER and HOLZMANN.
