Sanders and Sanding Machines

Sanders and sanding machines are used to finish wood, plastic or composites through the application of abrasive belts, discs or sheets. There are many different types of products, including two main types of belt sanders: contact-wheel and edge. Contact-wheel belt sanders consist of a driven contact-wheel and a tensioning idler wheel or pulley. Abrasive belts are mounted on both the contact wheel and the idler wheel. Workpieces are then ground or sanded against the abrasive belt. Contact wheels vary according to the degree of aggressiveness or finishing required. Edge belt-sanders (edge sanders) combine a driven contact wheel and tensioning wheel or pulley with an intermediate platen behind an abrasive belt. Platen types vary by operation and are constructed of smooth, low-friction materials that reduce heating and limit thermally-induced belt damage. Edge sanders or sidestroke sanders are a type of edge belt-sander. These sanders and sanding machines are usually stationary and feature a long, flat platen behind a horizontal belt-sanding surface.
