[kccadcam]

Did somebody say Plunge Milling????

 

 

Matsuura MAM72-63V PC2 Vertical 5-axis Machining Center

 

Seco 2 inch Plunge Rougher in Cat40 extended shrink-fit holder......

12.150 Gage length

5000 RPM - 50 IPM - .125 stepover - Sweet!!!

 

Part was turned inside before hand,

2 inch Mitsubishi Facemill pocketed both sides partway in,,

then Dive!! Dive!! Dive!!!

Absolutely Scary to watch it tool change!!!

Max tool length in the machine is 350mm!!

 

(No,,, I can't tell you what the part is....so don't ask)

Wheres the video!

 

BTW, no need to be secretive, it's obviously a flux capacitor charge head.

Looks like you could have been better off wiring out a majority of the part.

 

Sweet job though. Did you get much chatter with it hanging out that far?

Wire EDM would take too long.....

(if we even had one...)

At those speeds and feeds we had no chatter at all.. was really sounding sweet!!!

Great example of where directing the cutting forces axially along the spindle really helps.

 

What brand of heat shrink? Is that a Bilz or Haimer?

Actually, it's a Briney V40SF-125-600 that we had

to skim off about .020 from the OD.

(was the same dia. as the cutter)
