[clip]

I have a Cincinnati Saber 750 with an Acromatic 850 CNC Control on it when I try to power it up it has a Z over travel plus the T/C parked in front of the spindle like it want to do a tool change. Tried to hold in on the power button and jog Z down know luck. The machine is new to me. could use some help

My condolences.

The Cincinnati corporations went out of business for a reason. I'm afraid that the British built Saber was part of that reason.

try holding the master start, go to select, them mech/jog and press the mechinachal jog button on the left hand side.

You have to park the carousel before you can jog the spindle off the limit.The machine hasnt been dropped has it?

Cincinnati didn't go out of business, it was purchased by Siemens. The Saber I we have is extremely well built, with 10k rpm chilled spindle, 1000 ipm rapids from AC sinusoidal Fanuc drives, and unlimited program feed, rigid tap, and will hold a tenth all day long when properly setup.

FYI, they'd still be here today but Siemens killed the Acramatic control in favor of the 840D, etc. Many consider the Acramatic 2100 and 850SX to be one of the friendliest, most powerful controllers out there--despite Siemens ending their life.

I have a Cincinnati Saber 750 with an Acromatic 850 CNC Control. I must admit I am not very familiar with this control. I have a question concerning alignment. I am assuming this is like homing the machine with other controls please correct me if I am wrong in that assumption. The book describes witness lines to jog the axis to. On my machine I have a placard in the uppermost Z axis region. I found a pointer on the X axis and a couple of scratches that look like remnants of a witness mark. On the Y axis I have found nothing any Ideas where to look?

I have a 1250 with a 850sx control which should be the same as yours just bigger and to align the machine you need to press the align key to the left of the screen and it will align automatically. as far a witness lines you can for instance do what i do, which is to move the axis right before the limit switch and then press the align button by doing this it shortens the time it takes to align the machine.

Ive had several of these machines over the years. Overall a good machine and the 850 is a good control.

When you turn the machine on you must first use the rapid keys to align manually to the witness marks on all axis. There is a 1" by 3" card at the top of the z axis. If you cant see the "-z-" just center up to the card as best as you can. The x axis is marked on the front bottom edge of the table and if you look over the right hand side edge of the table and down toward the bottom inside the machine you should see some alignment tabs for the y axis. Match them up. When thats done press "align", machine will ask you "align axis", at this time press the align again and the machine will move around slowly and align itself.

Note: if you cannot see the witness marks at all you can try to move the axis' up, back and to the right all the way untill e-stop. Then press and hold the master start button while backing away just a little bit. You may need to try several times to hit the sweet spot but you dont have to be exact either. Make sure you mark that spot for the next time you startup.

Sometimes if you are too far over the overtravel dog, you need to turn the machine off and turn the ballscrew by hand (its easy) to lower it down or out of the overtravel zone.

As far as the tool carosel, you can push it back by hand out of the way if you depressurize the air cylinder. Dont worry, you cant break it. Just disconnect the air and if nec. unplug one of the air supply tubes attached to the cylinder to move it out all of the way back. Then your on your way. BTW I have repaired these air cylinders before, if they leak they wont work so you have to take off machine, dissasemble and replace the seals. $15.00. Or you can call Maintenance Technologies (current supplier of parts and service for cinci) and pay out the ying/yang for a new.

Good luck!

850 control has some really cool automatic milling cycles for pad, pocket and side milling. Have fun, I sure did.

Griz and Monster thanks for your help. I was able to align the machine. Have a great day

Does anyone have a programming manual for the Cincinnati Saber 750 with an Acromatic 850 CNC Control. I have all the manuals but the programming manual would like to find a digital or hard copy of it.

Thanks

[advt001]

ebay normally always has a manual or two

Again guys thanks for the help. I have several questions I am hoping someone can help me with. As I said before this control is completely foriegn to me. My other machine has a meldas control on it and this one seems completely different. First question: There again is no markings on the tool carousel to let me know which one is pocket one. I have moved through them until one of them took on the align button, but I have no real idea if it is number one or not. Any Ideas? Second I have heard that some of these machines rigid tap. How would I know if mine will ? It has a A850 MC control version 3.0 release 5/29/90. Third I am wanting to hook this machine to a serial port on my computer and use hyper terminal to transfer programs. Is this possible through the tape port on the machine? what would be the pin out for the cable? any info etc? 4th if anyone has a program that they would send me it would help greatly in modifying my post. I use visual mill 6.0 for cam. 5th I have no idea how to set up the tools and record the offsets, if anyone has some procedure that would be a great help. Something else that I am curious about is the fixture offsets. If someone can tell me how that works I would be greatful. Any help getting up and running would be great.

Thanks
