A Axis Constant Rotation

[1ctoolfool]

Is there a way to make the A axis continuously rotate like a spindle while performing some other xyz operations (I.E. deburring)?
thanks,

Yes, you have to spend some money..... it is an option.

From Haas??? Can you give a link to where it is mentioned on their website.

No, it is not from Haas, I think it was from Matsuki(something like that). I will try find the video link for you.

That is okay thank you. Because this is in the Haas Forum I figured you were referring to a Haas product.

As far as I know, you can not just "turn on" the A axis like a spindle with some sort of M3 like command. However, depending on the age of your machine control, you can input a very large number as the final degree value (in absolute) and thus rotate the A axis a large number of turns, which might be good enough for you... On mine I seem to recall I could get the thing to rotate at least 75 turns. Beware, although I could program or MDI these large values and they would execute, when stopped, after some large value, the handwheel no longer worked to turn the axis. --ch

I think I can do what I need with 10 to 20 turns, I was just curious especially after seeing the Hardinge direct drive rotary products. Their direct drive 5C can go 4500 deg/ sec. (around 750 rpm) vs my HA5C worm drive 360 deg/sec.

Now you really can turn your mill into a turn/mill center only control is still an issue.

Thanks, Joe V.

There is a "super speed" version of the HA5C at 800 deg/sec, obviously nowhere near as fast as the Hardinge... Gear drive vs. direct. I wonder if at some point Haas will bring out a competing product, or you will be able to "plug-n-play" the Hardinge into the Haas control. --ch

1ctoolfool:

With a stand alone external controller that had RS232 input you could use DPRNT commands to run the A axis.

Engraving and other continuous operations that require close instantaneous synchronization of the various axes would not work well with such a setup. But turning or positioning to a fixed location would work fine.

I think Haas do make it too, you have to find out from them.
