What speed should a deburring
|
||||
|
|
||||
| If you choose to use a machine (lathe, pillar drill, jig borer) to deburr the workpiece, the correct speed and feed rate must be selected. | ||||
Feed rate |
||||
 |
Feed rate is the speed at which the cutting tool travels across the workpiece being machined. It can also be the speed at which the material is fed to the cutting tool.
The feed rate is measured in SFM (surface feet per minute), this is how quickly the tool or material moves over the bed surface of the machine (lathe, pillar drill). |
|||
Speed |
||||
 |
The speed of a cutting tool is measured in RPM (revolutions per minute). This is the rate at which the workpiece or tool rotates. | |||
 |
||||
Finding the correct feed rate and speed |
||||
 |
To obtain the correct RPM (revolutions per minute) or SFM (surface feet per minute) for deburring, use this formula. | |||
| Below is an approximate guide to the feed rates of commonly used materials which may need deburring. | ||||

Brass / bronze |
Cast iron (soft) |
Cast iron (medium) |
Plastics |
Mild steel |
