Hi all, Just a quick one,.. while i am refurbishing my orac, i have powder coated the guards covers and cross slide apron, they have all turned out great.. does anyone know if 200 deg/c for 20 mins would hurt the bedways?? i.e. would it warp them or would be ok if i kept the frame the right way up ...

Thanks. I am looking to buy some software which would allow me to create a model of what I am hoping to machine, and generate a gcode program that I could then use by saving to a disk, opening in the text editor, and run on the machine. Is this possible, and which software would be applicable? The ...

Have you tried the reset buttons underneath the front panel ? ?

Regards
Rob

Hello All, I have a 1983 Orac with a spindle speed problem. When I start the spindle it reaches a constant speed and I am unable to change the speed using the -ve and +ve buttons. The bleeper is working but no change in speed. Hope somebody may be able to help. Does the machine change speed within ...

Hi all, can anyone tell me what the air demand is to run the atc on a Triac and any recommendations on which compressors do the job nicely, preferably a quiet running type! Thankyou, Rich. I use one of these http://www.machinemart.co.uk/shop/product/details/shhh-air-compressor-524 very, very quiet,...

Hi Rob The problem is actually that the machine will not return all the way home so I can't try any toolchange using MDI. It is falling just short. This does sound like some kind of obstruction but not sure where. I don't think sticking limit switch as that gives the over travel alarm condition. To...

. Have you tried to do tool changes using the MDI ? If not then home your machine and then try and do a couple of different turret positions and then do one for T6 and physically check that the turret has locked back into position correctly. I have had similar issues and it has just been a case of t...

Hi I have been running batch of parts and in the middle of one cycle, the machine has just suddenly stopped on it's way back to toolchange and the control is flashing <Not ready> and the green ON button is flashing continually. I've switched the control (and the machine) on/ off a few times but the...

i think mach turn needs the tool offset added to the tool number. Is this the reason for the repeating tool number? IE: M06T0303 ? cheers, v In addition to "angel-tech" some machines will also have an extra 03 for the TNR (Tool Nose Radius) settings, pretty standard on all the older Fanuc controls ...

The whole Fanuc AC servo setup eliminates any kind of drift, lag, brushes etc, the system uses encoders on the motors not tachos and the encoder signals are fed back directly to the Fanuc main board which gives a full closed loop system which is constantly monitored by the Fanuc, also all the veloc...

the motors may well be 3 phase driven, but the drivers are run off single phase. That's right - the Fanuc drives were always 3-phase Input supply and 3-phase Output to motors. As for the Triac Servo machine - it's possible to get servo drivers which accept step+direction input so if you can find so...

Hi Tom Quite possibly brushless DC motors, if so then yes, the drives would likely be 240V single phase in and and out, also probably runs sinusidal commutation from the motion control card. I have a set of 3 Aerotech DC brushless motors and drives with a 4 axis motion control card, I/O board and Op...

Normally on AC Servo motors the motors themselves are 3 phase, often the drives will accept either single phase or 3 phase in but the output to the motors is normally 3 phase. That would mean changing both the motors and drives, pretty expensive. If memory serves me right the Fanuc control doesn`t o...

I have just got a denford triac and found a supply of new Nikken BT35 tool holders in sizers 5/16 , 1/4 , 3/16 and shell holder is there any body else needing these tool holders so we could share postage cost cheers Mick Just my personal opinion but I think you should try to stick to Metric toolhol...

Bob Have you checked the output of the low voltage power supply, I seem to remember that the 1008 spindle error shows when the low volt control voltage is down, means there are no voltages for the Fanuc to check at the axis limits and it checks things in a specific order. Which can mean that the err...

Hi, Is the neutral actually connected? Three phase motors don't usually need a neutral phase but if there are any single phase loads then one is needed. The neutral is connected to earth somewhere in an electrical supply and yours can't be connect if there is 400volts on it. K Dickinson Keith The N...

Hi Bob It is a pretty big casting that mounts to the 3 machined faces along the front of the main casting and also sits on top of them. Here is a link to photos of a Harrison (Cyclone under another name :lol: )machine that was up for sale a while ago with a tailstock fitted. http://www.wotol.com/1-h...

My 2 cents worth :mrgreen: :mrgreen: You have to set up your machine offsets first, most used method is to "touch off" your piece of stock on both the X and Z axis and input the the offset values to the machine offset screen. "MENU OFSET" key on your top right keypad to get to the machine offset scr...

Saw this auto tool changer for small lathe on ebay, thought it might be of interest to Orac owners.

There is a small video showing it fitted to an Orac Lathe.
