M5 before M52. I ran cross your post somewhere about tapping with live tools. I've only been successful with G33.
Do you understand that with a Mesa card you don't need the AC95 at all? That machine has little beyond the VFD and stepper drives. Most people just thread mill when they can't tap. Do you have...
If the machine runs on the original hardware and software, why switch to Linuxcnc? I guess I don't understand which Emco components you intend to keep. That machine is a basic machine. If you need...
Contact Emco, they will set you up with software and MSD for your machine. MSD are somehow verified by serial number. Any manual edit of the file locks the machine, changes need to be made with...
It looks like the actuator only has one ring of set screws. I'm not sure if anything else is used to balance that spindle. Mine has two rows of set screws. Without sensors to measure vibration and...
If you've already played with the setscrews, you're out of luck. The spindle requires proper dual plane balancing. If you can find someone to come out and do it for a reasonable price, that would be...
If you didn't mark the orientation of the actuator before taking it off, you'll need to rebalance the spindle assembly. Depending on how far you disassembled, you may be able to find the proper...
LOL, my 325-II works with M4, but this isn't a real Fanuc control. Have you ever looked at the spindle drive paramaters? Someone turned off braking in mine. I had to guess at the settings as Emco...
ACC is specific to the machine to some extent, but I don't know details, just what I saw when looking at photos, a mill ACC won't work for lathe. ACC takes a compact flash card with data for the...
Look at page 35 of the electrical documentation for LEDs on the drive. LED1 indicates if the drive is ready. Others indicate faults. If there is no LED, troubleshooting begins by checking the fuse in...
If the machine has ACC any PC will do. Contact Emco with your serial number and they will get you all the documentation and software you need.
The logic for the sensors is pretty simple. One sensor checks that the tailstock extends when commanded, so the machine doesn't try to run without the stock engaged. The second checks for overtravel,...
That's great. Must have 1:1 pulley ratio? Compact 6 is 80%.
This is not the best way to achieve the RPM required. Most certainly the motor can easily handle 120Hz, (check the MFG for max RPM it's probably 6kRPM.) By increasing motor pulley diameter you've...
As these machines are clearly getting old, PCB begin to fail. I had an intermittent connections on a couple boards in a pair of machines. This lead me to reflow solder joints on all connector...
WinNC is not Siemens so probably won't find help here. You must have an older Emco AC95 control and a 325-II? Essentially AC95 is not supported any more and they want you to upgrade to the Concept...
How do you use standard BT30 in the turret? Any pictures of how you're doing it? I'm curious because this would be the main reason I avoid this machine, if one was available.
Emco had a spec in mind and built these machines to that spec. These tabletop Emco are teaching machines. Imagine students crashing every session and the machine needing an axis rebuild. They often...
You can't ignore the torque of the stepper if you've crashed the axis. Emco built all of these stepper machines with the motor not being strong enough to damage the mechanics. The little 8x2.5 ball...
Did you see this machine on Craigslist? https://london.craigslist.co.uk/bfs/d/emco-pc-mill-155-vertical/6378398921.html Make sure it's real. Ask for a photo of the serial number so you can contact...
Can you get the spindle to run at all? It seems to me the control is expecting the spindle to start and is not getting spindle speed response. If you are hearing noise when the spindle should be...
It has four bolts threaded into the frame for feet, You'll want to remove them. It moves with a pallet jack, but most of the mass is on the mill side so pay attention to the center of gravity.
Did you buy that one in Virginia? The biggest pain is that they are wired for 3 phase power. If you are already setup with 3ph, this is no problem. If everything is in order it should power up. The...
I'm struggling with errors with my PC Turn lathe and would like to reinstall WinNC. Some software is available on the Emco site, but not the older AC95 versions predating the Concept control. Emails...
I've started modifying some BT30 holders to fit my PC Mill 125. Turning the flange off is quite a bit of work, especially if it's a quality holder with high hardness and case depth. The pull stud end...
What is the error? M21, chuck must be clamped, and the tailstock prox must be set according to manual. If prox is not set it, will give error about sleeve position, check your pm.
The 120P manuals show a pressure switch between chuck valves and actuator. If pressure fails here, machine errors and stops. This indicates the machine would have pressure to the chuck at all times....
The pneumatic drawbar actuators rotary union is lubricated by oil in the air so there is always pressure to the chuck. Loss of pressure should not release the chuck because there is a safety valve in...
Tsubaki 12x5mm screws in my Compact 6 had nominal 3/32" balls. I bought balls from Baltec when I rebuilt them, 3/32", .093616", and 093413". I ended up using 3/32 and one of the others(X and Z screws...
It's very common in bearings. Emco can be a bit slow, especially if you don't have a part number, hopefully you included a serial number.
