    VDF Lathe Spindle Shutting Off

    We have a 1996 VDF DUS 800 lathe with a Siemens 805 control at work. It’s old, but new to me and nobody else knows how to run it. If I program G96 S500 M3 then G00 WHEREVER in a separate block, the spindle will shut off. If I program the same information in one block, it stays on and works as it...

    VDF DUS 800 Drive Fault Alarm

    Time for an update. When I first started trying to resuscitate this lathe, the backup battery had failed and the first task was to re-initialize the control and re-load the appropriate backup data. After this, it would not come out of e-stop until we tracked down a fault in the rear access door...

    VDF DUS 800 Drive Fault Alarm

    Thanks Peter. I will follow your lead. Would you be the Peter from 600 Group days? So far retirement is good but I stumbled upon a great job so I took it. A few more years of income and benefits won’t hurt me. Glenn

    VDF DUS 800 Drive Fault Alarm

    The company I recently started working for has a VDF DUS 800 that is not functioning. It appears that the backup battery failed. I have replaced the batteries and re-initialized the control and the operator panel boots up properly but the drives will not energize after the boot-up. The Simodrive...

    Torcam Lathe

    I posted this here because I found people on this site looking for the same information that I was. I don’t know if they got their machines running because there was no follow up post. There are a few of these machines around and the information I posted will help people who are trying to get...

    Torcam Lathe

    I was recently asked to get a Torcam lathe operating and like most of the internet posts I could find regarding this brand of machine, it was a lathe and control box that was missing the original computer and operating software. I found most of the information I needed on the internet but not a...

    Poor Surface Finish on Lathe

    ifixcnc; Mechanically included ballscrew play x and y (none)spindle bearings (good) and whatever else they could think of that was measurable in the machine. They also checked backlash compensation. The ball bar test showed several issues that needed correcting. They were corrected but to no...

    Poor Surface Finish on Lathe

    Vancbiker; The regenerative braking unit is not used and there is a jumper on the TH1 and TH2. Any ideas on where the 430 thermal alarm would originate? Glenn

    Fanuc Beta servo motor thermal alarm 430

    The position of the axis is visible on the CNC screen but the System, Diagnostic information which shows motor and encoder temperatures is not displayed. I believe, and I may be wrong, that Beta motors have a "make or break" function to temperature control. If I can find information on encoder...

    Fanuc Beta servo motor thermal alarm 430

    To All; We are having a problem with a Fanuc B2/3000 servo motor in a bar feeder. It runs for a few hours and then stops with a 430 Thermal Alarm. The motor itself is not getting hot, it measures ambient temperature (82 F) when we check it. I believe that the Beta motors and drives are a "low...

    Harrison Alpha 400U For Sale

    Hi Don; I prefer to think in metric but there are still a lot of imperial drawings that come our way. We set the machine up in inch a long time ago and it stayed that way. The fixture on the 3 jaw is bolted to the surface of the chuck to eliminate any run-out issues. The touch screen guard got...
