热熔钻安装

Drilling manually (Operating by hand)
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 Lubricate the tool
11 Perform the drilling operation in a constant downward motion (no dwelling!)
12 When depth is reached retract the tool as fast as possible
13 Observe cycle time and drill color
14 Adjust when needed the speed (See step 8 & 11)
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 Fdrill is used you need to accelerate the feedrate just before the cutting starts:
This acceleration will increase tool life of the cutters significantly
The length and shape of the produced chip is a good indication:See picture
