Wide Belt Sander

Wide Belt sander Introduction

A wide belt sander has the following parts: a base, a driving device, a driving axle, a driven axle, an axle bracket, an automatic adjustment device and a belt. The bottom has the central axis and axle is mounted rotatably on it. The base also has the driving device mounted on it and it is connected to the axle (driving). Along a longitudinal axis that is perpendicular to the central axis of driving axle, the axle (driven) is also mounted on it. Along the rotating axis and parallel to the central axis of axle (driving), the axle (driven) is mounted rotatably. And around both the kinds of axles, the belt is fastened endlessly. There is an automatic adjustment that is mounted between the driven axle bracket and the base in order to swing in a harmonic motion.

To achieve a desired finish on the particle board or wood, large belt sanders are often used for commercial sanding operations. They come in many shapes and sizes and also have minor variations from machine to machine. Some are simple with single contact roller with circumferential sanding belt to very big and complex ones to carry continuous belts of varying lengths. The surface of the belt loads or fills with materials abraded from the subject during the sanding operations and becomes glazed. The glaze eventually inhibits the sanding operations because smooth surfaces are considered unfit for such operations.

The usual practice is to dispose the glazed belt. This is considered a waste and expensive too. This not only increases the expenses but also the downtime of the machines while changing the belts. All belt sanders have many safety features like belt tracking limit switch, emergency stop button, safety bar and most often these machines switch off automatically when the power is cut off. These machines are also available in different series. The sander is used mostly for easily and quickly removing and leveling.
