i know this has been answered already and this might be annoying but i just have to be clear on this for my specific machine. but will a sandvik corochuck 930 hd big plus ct 40 work in a 2012 haas vf-2 CT 40 spindle? and will any problems come from tool changes., it has a magazine style tool holding system.

Looks correct to me he said 5/8 Counter Bore using a 3/8 endmill. Do you have a specific question you need help with?

I completely missed the c/b  and also misinterpreted the answer, i was thinking of something at the time, my bad.

I have been playing with 1.5 to 3 degrees and it seems like the sweet spot. Its just to bad you can't input 3 degrees into the Helic bore operation, "Set it and forget it!", but instead I do the math. But I may have found a quicker way to get rough pitch,

Center of cutter diameter divided by 6 will give me roughly 3 degrees, as opposed to getting circumfrence and multiplying by 3 degrees.

 

.625-.375=.250

.250/6=.041

 

 

As far as feedrate, my coworker suggested using,

c/b diameter minus tool diameter divided by c/b diameter multplied by normal feedrate

 

5/8 diameter c/b, 3/8 endmill. normal feedrate would be lets say 12. IPM

 

.625-.375=.250

.250/.625=.4

 

12 x .4= 4.8

 

4.8 IPM adjusted feedrate

 

These may not be optimal, but I am looking for more consistency than anything, so operators will at least know what to expect.

hey just wondering if you meant .625-.3125  not .375. unless i read your comment wrong.
