| 2. | Cutting tool too small. | 2. | Use larger cutting tool and slower feed rate. |
| 3. | Cutting tool getting too hot. | 3. | Use coolant fluid or oil for appropriate application if |
|
|
|
| possible. |
| 4. | Taking too big of a cut. | 4. | Lessen depth of cut and allow chips to clear. |
| 5. | Spindle extended too far down. | 5. | Fully retract spindle and lower headstock. This |

|
| slower feed rate. |
| 2. | Using dull or incorrect cutting tool. | 2. | Sharpen cutting tool or select one that better suits |
|
|
|
| operation. |
| 3. | Wrong rotation of cutting tool. | 3. | Check for proper cutting rotation for cutting tool. |
| 4. | Workpiece not secure. | 4. | Properly clamp workpiece on table or in vise. |
