Okuma Horiz.

[SLJ]

We are getting a used (not my choice) Okuma MA-400 Horizontal with OSP-E100 control to move some work off the new Makino A61 we got this spring. I've been going through the book and a sample code file they sent me and getting the generic post tweaked with the dealers help. For those who've used one of these machines, is there anything to watch out for? Special tricks?

Sorry, can't help you, but's wrong with the Okuma? It's used, or the builder?

We have a mx-40ha and a ma-600hb here is some code from our post.

We have an MA-50......works fairly decent......

 

The only issue we have is when using the ID coolant with small drills. After a while of the coolant pressure the seal seems to get a leak and it starts to rot out the spindle. Ours is about 7 or eight years old and we had to have the spindle head removed and repaired twice........And NO there is no limiter to reduce the coolant flow.......we did try to pit a bypass valve in but when the drill was deep the pressure DID bypass where there was almost/no coolant at the drill.......

Nothing wrong with Okuma that I know of, we're an all Fanuc shop and the controls are different so that is why I was asking.

Thanks for the code Beck, do you use the high speed look ahead? Was wondering how you went about spec'ing the E(tol) value.

[Greg Williams]

In-house have a very nice MP-Master Okuma post. Have your dealer contact them

 

Has your machine got Super Nurbs or Hi-cut pro option?

 

I use these values in Metric G131 J2 E0.025 F10000 for roughing and G131 J1 E0.02 F10000 for finishing.

 

If you have super nurbs there are a few more options

 

Rough G131 J2 E=0.03 D=0.01 I0 F10000.

Finish G131 J0 E=0.025 D=0.01 I0 F10000.

[beck250]

Yes we use it I either set it at the machine or put it in the program the same way greg described but with inch values and I use J2(high speed)for rough and finish the tighter you set the E tolerance the more it will slow the machine down.

[SLJ]

Not sure on which option, the sample code they sent me and the book shows a G187H1FxxxEyyyy with the F being max feed cap, E=tolerance. This machine was transferred in from a sister company to take the load off the A61. I don't know how old it might be, or how tight. They are installing it today. Hoping to cut tombstones Monday.

SLJ,

 

this is how i control my okuma's U100M control.

 

phinca # Super Hi-NC Control Selector

if mi8$ = 1, "G131J0I0", e$

if mi8$ = 2, "G131J1I0", e$

if mi8$ = 3, "G131J2I0", e$

if mi8$ = 4, "G131J0I1", e$

if mi8$ = 5, "G131J1I1", e$

if mi8$ = 6, "G131J2I1", e$

if mi8$ = 7, "G131J0I2", e$

if mi8$ = 8, "G131J1I2", e$

if mi8$ = 9, "G131J2I2", e$

if mi8$ = 10, "G131J0I3", e$

if mi8$ = 11, "G131J1I3", e$

if mi8$ = 12, "G131J2I3", e$

if mi8$ = 13, "G131J0I0K1", e$

if mi8$ = 14, "G131J1I0K1", e$

if mi8$ = 15, "G131J2I0K1", e$

if mi8$ = 16, "G131J0I1K1", e$

if mi8$ = 17, "G131J1I1K1", e$

if mi8$ = 18, "G131J2I1K1", e$

if mi8$ = 19, "G131J0I2K1", e$

if mi8$ = 20, "G131J1I2K1", e$

if mi8$ = 21, "G131J2I2K1", e$

if mi8$ = 22, "G131J0I3K1", e$

if mi8$ = 23, "G131J1I3K1", e$

if mi8$ = 24, "G131J2I3K1", e$

 

i have all the options predefined in the control

then i select the fidelity in need in the operation. at the end of the op it cancels with a G130.
