1 | Choose the right tool (Diameter & Style) |
2 | Make sure your machine meets the tool requirements for speed and power |
3 | Make sure your machine meets the requirements in axial force |
4 | Assemble the tool holder correctly |
5 | Insert the Formdrill into the tool holder and tighten the nut very tightly |
6 | Insert the tool holder in the machine spindle |
7 | Clamp your work piece securely |
8 | Consult our wizard page for machining depths and feedrates |
9 | Lubricate the tool |
10 | Perform the drilling operation |
11 | When depth is reached make sure the tool retracts as fast as possible (no dwelling!) |
12 | Observe cycle time and drill color |
13 | Adjust when needed the speed and feedrate (Step 8). 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 |
