    304L VAR machining

    Ha!! Free lunch, now you're speaking my language. I'm pretty new to the lead role so my experience with vendors is basically non existent. I'm in Western Washington, just east of Seattle.

    304L VAR machining

    Yea i have muddled around with the speeds and feeds but havent had much luck. The new inserts just came in and im hoping they will help. And yes we have experienced the gravel sound with fresh inserts as well. I am running thru coolant as well as a nozzle. I dont have a walter rep, per say, just...

    304L VAR machining

    Material consistency has been a big part of the problem for us. My production manager is the one that orders all my materials and he swears that only one company make VAR material... I have no idea how accurate that is but hes 72 years old and arguing with him is futile. We are primarily a job...

    304L VAR machining

    The vendor that originally turned us onto this drill said 2500rpm which is about 430sfm. That seemed really fast to me and we were going thru inserts like crazy so I turned it down to 1100rpm, which I got from Walter but you may be right about it being too slow. I just ordered some inserts with...

    304L VAR machining

    Hi guys, I am having some trouble drilling in 304 L VAR. Background: using a Walter B4213 indexable insert drill (.656") in a Mori Sieki SL200 lathe, drilling 1.375" deep hole on center. Currently running 1100 RPM @ .0025 IPR per Walter app. Problem is the inserts deteriorate much much faster...

    Hardinge Conquest CS-42 power issues

    The display is blank. No lights comes on. Nothing at all. The three glass fuses under the top board were good. I replaced them any way for good measure.

    Hardinge Conquest CS-42 power issues

    It is unfortunate. It is what it is though. I'm learning a ton about this machine from working on it. It's frustrating and a bit disappointing but I haven't lost hope yet. It's definitely been a humbling experience so far. It's going to be a real treat when that first chip falls.

    Hardinge Conquest CS-42 power issues

    $3500?! Yikes. I might be screwed. I have been in contact with the previous owner but I mostly just get "wow that's wierd, never seen those alarms before." Not very helpful. And unfortunately the machine was purchased as-is. Which at the time, when I saw it running parts, I was fine with. I...

    Hardinge Conquest CS-42 power issues

    I've been CNC machining for a little over a decade now (not long in comparison to some), but I have zero experience with the electronics involved in CNC machines. I've replaced ball screws, bearings and solenoids, but this is new to me. However, I spent everything I had just getting this far...

    Hardinge Conquest CS-42 power issues

    Hardinge and fanuc support are saying the drive needs replacement. I'll be pulling it out and attempting to repair it myself. I can't afford to replace this unit so it's time for a crash course in servo drives. Hopefully when it's on the bench the problem will be more apparent.

    Hardinge Conquest CS-42 power issues

    I have 3 phase power going to the drive. I checked where the hot lead come from the breaker, to the junction block, and at the board where the power comes in. All check good for power. So the drive is getting power, just not turning on. I also replaced all the fuses and none are blown.

    Hardinge Conquest CS-42 power issues

    After consulting with Hardinge, and sending pictures back and forth, It has been discovered that the spindle drive has no power. Not sure why yet but I am tracing wires and will locate the problem eventually. Hardinge tech said to check all breakers and fuses, which I have done, but I am...

    Hardinge Conquest CS-42 power issues

    Well, I finally decided to contact Hardinge. I should have done that to start with. They sent me all three manuals and all wiring diagrams for the machine. Still working on a solution but the Hardinge service team has been outstanding. Especially for supporting a 34 year old machine. I will post...

    Hardinge Conquest CS-42 power issues

    I agree that it is likely one issue causing them all. The machine traveled roughly 40 miles. I dont know if it traveled on air ride. The riggers are very competent and I have used them before times. Phase is good and hydraulic pressure is good. It took some trial and error to get the power...

    Hardinge Conquest CS-42 power issues

    I manually oved both axis off the limit switches and went through every wire connection I could find and found no loose wires. Neither helped. I am getting 24v. The spindle brake always locks as soon as the hydraulics kick in. I don't know if that's normal. I cannot move any axis, or go into...

    Hardinge Conquest CS-42 power issues

    Ok that makes sense. I will check for the 24v. I am also going to check limit switches and whatnot because it seems that its in an emergency stop state. I don't know. Im really just checking everything at this point.

    Hardinge Conquest CS-42 power issues

    I've seen this 24v mentioned before but am not sure what it is in reference to. Control is Fanuc 0T I did see it running production and working well before I bought it. It was in storage for about 3 months. I wired a buck boost transformer today and it lowered my voltage to a nominal 219v...
