Hello,
I have two questions, and was hoping someone would have some advice.
- 6061 Aluminum
- Haas VF4-SS with TSC
- Mounted to HRT-160 and 2x 5th Axis Picatinny Rail Mounts
You can probably guess what I'm making, but I need to drill a 1.000" hole 7 3/4in deep in 6061 Aluminum (later perhaps 7075). I have bought the bar and insert, and my machine is equipped with Through Spindle Coolant.
I suppose I'm a little nervous about this cut and was hoping someone could tell me if I'm crazy or not! (At least in concern to this one cut!) I am worried that my fixture isn't stiff enough, my machine not strong enough, or this cut too aggressive to accomplish my goals. I try to run my machine as conservatively as possible, since I own it myself and don't have a boss with a checkbook who will pay for mistakes.
I was thinking a starting at 600 SFM and .010 to .012 feed/rev. That translates to 2291 RPM and 22.9 IPM. Seems really fast to me. I am planning to plunge with no chip breaking.
Here is the tool:
Here is the part and fixture:
Datasheet for the tool:
Better image for my workholding (this isn't the correct orientation)
Am I overdoing it? It is highly desirable not to have to make another fixture as I plan to mass produce these, but is that necessary?
Thanks!
