Let's see some machine work

[mklotz70]

Comic book?  I must be old or one of my two brain cells is asleep.  Crossover?  Like in the movies where the two guys switch?

 

You want to be a short, old, fat guy?  Sure...I'll trade you :)

 

If you want to visit.....I'm cool with that too :)

[Mattndew76]

Lol I will stop by to see the shop.

[mklotz70]

Guess I'm stuck being a short, fat guy.......crap! lol

 

Let me know when you're going to be up here.  It's small and there's not much to look at, but I enjoy other guy's shops, regardless of size/shape.  Maybe I'll have the mill running when you come up. :)

[Mattndew76]

I will do. Your shop..by watching your Mill assembly vids is larger than the current building housing my CNC

[mklotz70]

Cool.

It's barely a car and a half garage.  At least you are using yours! lol

[Mattndew76]

When I first got my CNC mill it sat for 6 months because I had no clue how to hook up the power

Crossover... Like when Superman and Batman team up in the same comic book for one book or maybe a short series.

Blue Hands, Blue Balls?

[Mattndew76]

I'm MD-Machinist not blue balls. Unless the wife forgets me in the morning.

That is a serious amount of adjustment screws! The gibs on most of our machines are just wedge shaped and threaded in each end to push it tight or loose. Lookin good Mr. Klotz!

Just a quick video.  Been working on this for the last week, lot of material that needs to go bye bye.

 

1018 Steel, old ass HAAS VF2.

 

 

[Josh K.]

Plunge milling. Nice way to overcome lack of torque on the vf2. Good stuff. I love cnc :)

 

I have to get our newest 5axis doing full simultaneous 5axis tomorrow. Buying options for a used machine is a bitch!

They're straight gibs instead of tapered gibs.  I'd much prefer linear ways :)

Thanks!!

Lack of torque on the spindle? 

[Josh K.]

Yes. Haas machines and most entry level VMC's have pretty low torque at lower rpm's so doing hard metals can be a challenge. Typically for steel hog outs you would use like an AJX type high feed Cutter. This would take a shallow DOC (Axial Depth of cut) and a High RDOC (Radial Depth of Cut) at a high chip load do to what's called "Chip Thinning". So let's say you would use a 3" cutter (Indexable body) at 350SFM (445RPM), 0.050" DOC, 2.25" RDOC (75% Step Over) and 0.025" FPT (Feed Per Tooth, Appx 50IPM Depending on how many inserts). This would stall out most Haas Machines pretty quick like. This scenario would result in 6.3 Cubic Inches Per Minute of Material Removal. 

 

Now on a lower torque spindle you would normally use like a 0.625" Indexable Endmill running 500SFM, 0.500" DOC, 0.100" RDOC, 0.015"FPT. That's 3056RPM which puts you up in the torque range of the spindle and allows you to go faster. This scenario would result in 4.6 Cubic Inches Per Minute of Material Removal.

 

What he's doing in the video is call "Plunge Milling" which is another great method of removing material when you have the right application. You're basically drilling with a shallow step over but the rigidity of the machine is less important.

[mklotz70]

Thanks Josh!!   I only have a 2hp spindle on the Pro.....I'll have to keep it in mind....maybe I can use it.  I guess that's provided whatever CAM I use can do it.

[mklotz70]

Not impressive at all, but it's steel :)  I'm pretty sure it was a 17" rim!!

 

[Josh K.]

Got 5 axis working sweet!

 

 

[Mattndew76]

I did a couple :15 videos of side milling on a cover.

 

Basic stuff

 

Posted it to Instagram.

[Josh K.]

Here's the part I was making in the video...

 

 

[captaingamez]

What is that?

[mklotz70]

How did you get the square slots on either side of the holes?

[Mattndew76]

Micro woodruff does great square slots.

 

Nice trunnion work. Wish I had one.
