Woodworking sander

A woodworking machine that sands the surface of a workpiece with abrasive belts and abrasive cloth (paper). Woodworking sanders are divided into three types: drum type, belt type and disc type.

The drum type woodworking sander adopts the roller sanding wood which is wrapped with abrasive cloth (paper), and has two types of single roll type and multi roll type. In addition to the rotation, the drum can also be axially reciprocated to reduce the surface roughness of the workpiece. The single-roller sander is mostly fed manually, and the multi-roller workpiece is fed by the press roll and the upper and lower feed rolls or the conveyor belt. This type of sander is suitable for sanding surfaces such as sheet metal plywood, plywood, particle board and fiberboard.

The belt type wood sanding machine tensions the endless ring belt on two or three pulleys to drive the belt for continuous movement, and a tensioning wheel also makes a small amount of tilting to cause the belt to move laterally. Sanders for surface machining have fixed or moving tables; sanders for surface machining use the flexibility of the belt to machine the workpiece under the pressure of the template. The wide-band woodworking sander (Fig. 1) has the advantages of high efficiency, guaranteed machining accuracy, and easy replacement of the belt. It is suitable for sanding of large-scale wood-based panels, furniture panels and decorative panels or before and after painting.

Woodworking sander

The disc wood sander uses a sandpaper (cloth) that is placed against the end surface of the rotating disc to sand the workpiece (Fig. 2). There are vertical and horizontal, single and double discs. The workpiece is fed manually or motorized for flat sanding and is suitable for use in the manufacturing of cars, furniture and wooden moulds.
