Description
The 4S4H4W uses a continuous feeding process. The wooden workpiece is fed through the machine while different sanding heads perform surface processing at different positions.
The sanding heads can be arranged and adjusted according to the workpiece profile. Depending on the required finish, the machine can combine sanding belts, sanding wheels and other abrasive tools.
During operation, the pneumatic pressing system helps stabilize the workpiece, while variable-frequency feeding allows the operator to adjust the processing speed according to the material, abrasive and sanding requirements.
The 4S4H4W is designed for linear solid wood components with a processing width of 50–150 mm, thickness of 15–100 mm and minimum length of 680 mm. Typical applications include wooden strips, door frames, picture-frame moldings, furniture components and decorative wood trim.
