Hello guys
That may sound a bit weird now but I need some advice about drilling with a 3,5mm VHM Spibo.
I am working on a boring machine and the normal machine are more than 30mm plus.
We need to make through holes with a 3,5mm Spibo into a plate t=15mm.
IKZ is not available, only an external cooling.
The time doesn’t matter-the processing only needs to be safe.
What can you recommend? VC, Fu, chip breaking? Air?
Oh and S max are 2500 rev/min
Frohe Grüsse Stefan<br /><br /><div align='center'><!--fonto:Comic Sans MS--><span style='font-family: "Comic Sans MS"'><!--/fonto--><!--coloro:#FF0000--><span style="color:#FF0000"><!--/coloro--><!--sizeo:6--><span style="font-size:24pt;line-height:100%"><!--/sizeo-->Ein Tag ohne lächeln ist ein verlorener Tag<!--sizec--></span><!--/sizec--><!--colorc--></span><!--/colorc--><!--fontc--></span><!--/fontc--></div>
