|
1 |
Choose the right tool (Diameter & Style) |
|
2 |
Make sure your machine meets the tool requirements for
speed and power. |
|
3 |
Assemble the tool holder correctly |
|
4 |
Insert the Formdrill into the tool holder and tighten the nut very tightly |
| 5 |
Insert the tool holder in the machine spindle |
| 6 |
Clamp your work piece securely |
| 7 |
Make sure the distance between work piece and drill bit is limited |
| 8 |
Set the correct spindle speed for the tool |
| 9 |
Set the correct drilling depth |
| 10 |
Set the correct feedrate (between 0.1mm/rev. and 0.15mm/rev. or spindlespeed
divided by 10) |
| 11 |
Lubricate the tool |
| 12 |
Perform the drilling operation in a constant downward motion (no dwelling!) |
| 13 |
When depth is reached make sure to retract the tool as fast as possible |
| 14 |
Observe cycle time and drill color |
| 15 |
Adjust when needed the speed and feedrate (Step 8 &
10). To much heat: Lower
Rpm or increase feedrate or both |
| |
| |
|
Working with Flat style drills |
| Attention:
A hot chip is produced - use a guard to protect machine operator and
surroundings |
| When
a Flat style Formdrill is used you need to accelerate the feedrate
just before the cutting starts: See
video |
| This
acceleration will increase tool life of the cutters significantly |
| The
length and shape of the produced chip is a good indication: See picture |
