Disc and Disc Belt Combination Sanders

The disc sander consists of a reference table and a circular plate mounted to a motor shaft. A cloth or paper-backed abrasive disc is cemented to the plate. The diameter of the disc indicates the size of the machine, commonly 12”. The combination sander includes a vertical belt sander as part of the machine.

1. Hold the work securely.

2. On the disc sander, always sand on the downward-traveling side of the disc.

3. Do not sand stock that puts your fingers within 2” of the abrasive.

4. Apply moderate pressure to the stock against the abrasive and keep it moving. Excessive pressure can overheat and damage the abrasive.

5. Keep the stock moving to avoid overheating the abrasive material.

6. Be sure the work is held firmly against the table.

7. Use the disc/belt sanders only for sanding straight edges or outside (convex) curves.

8. Do not use the sanders for joinery, squaring stock, or other similar applications.

9. On the disc sander, make sure the disc is secured properly. Notify the instructor if the disc is loose or worn.

10. On the belt sander, make sure the belt is tracking properly. Notify the instructor if the belt is loose or worn.
