I、Brief Introduction

A sander is a power tool used to smooth surfaces by abrasion with sandpaper. Sanders have a means to attach the sandpaper and a mechanism to move it rapidly contained within a housing with means to hand-hold it or fix it to a workbench. The automatic turning sander is widely available on Veneer production process, the production of standard parts, toys and crafts industry, decoration and furniture industry, floor wall panel building materials industry, etc..

II、Technological requirements 

Knob down（drivers start）→Start grinding wheel→Starting conveyor belt→Conveyor belt up or down→ Device fully activated

III、Characteristics

Woodworking sanders are usually powered electrically, and those used in auto-body repair work by compressed air. There are many different types of sanders for different purposes. Multi-purpose power tools and electric drills may have sander attachments.

1. Simple operation
2. High degree of automation
