    How to use a SPEGO bar feeder on Hardinge T-42

    We have a Spego 66-13 hydraulic bar feed that came with the machine we bought a few years back. It advances and retracts in manual mode. Beyond that I have no idea how to use it (in Auto). Our other machines have pneumatic feeders, with air on, open collet, move, close collet. Can anyone...

    Hardinge Servo Retrofit

    I have a Hardinge CHNC II with dead DC servo drives. I would like to replace the drives and motors with AC Drives. I have removed the DC stuff from the cabinet. Wires 47 and 49 come from the GN Fanuc 10TF control with a black/white pair labeled "speed +-" and a brown/white pair labeled "tach...

    Hardinge T42SP Z Axis Jump

    I should have mentioned the machine is new to us, but mid 90's vintage. It got bounced around enroute, but is repeatable to within what we can measure here, and responds to an offset of .00005" Parameter 1851 on the Z is set to 750, others are set to zero.

    Hardinge T42SP Z Axis Jump

    Hi guys, looking to crowdsource some knowledge. Recent purchase of T42SP upgrade from CHNC-II. Part is super high precision with a Zneg Xpos move turning into a Zpos Xpos move, followed by a Zneg Xpos move. These angles result in just a few thou of movement but the angles need to be...

    Bar Feed Program

    That helps a ton! I was not the one from before. My question last week was about a torque reset on the axis drive. I will do another search though in the forum. I was looking at it completely backwards, thinking the CNC passed the length info to the feeder. Now that I understand HOW it works, I...

    Bar Feed Program

    Thanks Oz, and thank you for the help last week with my crash error! There is something that I must not be getting through my head. I thought that you called M61 to check and see if end of bar was reached. If so, it retracted remnant, loaded new bar, ran top cut... just like the three...

    Bar Feed Program

    With a 'new' Hardinge T42SP and LNS mini sprint bar feeder, I am trying to figure out how to program the feed stock step in the program. Until now we had a Hardinge pneumatic ram that shoved the bar out when you opened the collet. There are no programs left in memory to use as a guide except...

    Hardinge T42SP Z torque limiter reset

    Sorry, it was 'z overload'. LSI overflow on chnc. To home, don't you have to first jog Z- and X- ? This is when it pops back out.

    Hardinge T42SP Z torque limiter reset

    RE: Sweet Spot... I am able to hold e-stop reset, and zero return to get it to jog. I can move the X+ and here a bit of a click, if the axis continues to move another click will be heard. I can do the same in the X- until I overtravel ( note: overtravel seems to bee too far X+ ). There is a...

    Hardinge T42SP Z torque limiter reset

    I know this was a few years ago, but I am having the exact same problem on the T42SP. This is a new machine for us, and I crashed the cross slide into the tailstock with a X- move. I followed the procedure to realign the tailstock. Using the jogging info above I have found the sweet spot...
