Getting this alarm now..
1008 spindle unit fault and 409 servo alarm on the hardinge..
was running parts fine.. it seems like i am having nothing but power problems in this new shop.. but maybe its just happening because the machine was due..

anyone have an idea .. ? here is a pic..

We are making a new 5MT tapered dead center. Need extra clearance for the tool to get in and cut smaller diameters. What is currently in the tail stock is a live center, but the tail stock also has a bearing. We are getting a .002-.003 movement when we push on the part. We also have this dead center that is much to short and would not be able to cut anything under 4" or so. I was looking for some input on how to go about making one, or any other advice on trying to make this tail stock more rigid. I have included pictures of the two existing centers.

Thank you.

I`m looking at a new small VMC and was looking at the newer MS500 scraper conveyor for it. does any one have any feedback on how they do with small to fine aluminum chips? I searched but cant find info on the newer models after they did away with there wash down drum system.
Thanks

Hello,
I'm trying to improve my positioning accuracy by using the G60 code during a bore cycle. I tested my G60 command using G81 and everything looked fine, but when I use G76 I expected to see the table take-out back lash in the Y axis but it did not. Let me explain further; when I execute my G76 command my boring tool bores to depth, dwells, orientates spindle (M19) and slightly (.0025") vectors the tool away from bore wall in X and Y axis before retracting. Since my Y axis position has been altered why doesn't G60 take out Y axis backlash before it positions on the next in-line hole? It does take out the X axis backlash. I change (increased) the parameter value that over rides the G60 move so that I can see it more clearly.

N2G43H4Z2.

So, here I sit, beverage in hand. Thinking
At the day job, we do a fair bit of 4th axis rough out (square shapes onto turned profiles).
Ive taken to doing some plunge roughing to speed things up, and its fine and all. The thing I hate is "index, plunge, rapid up and over, plunge, repeat". The majority of my travel lengths are spent rapiding up and over instead of feeding.
What I want to do, is to "lock" the tool at say 30 degrees from perpendicular, and plunge rough down, over and along, then performing a helical move longitudinally along the part, while interpolating the rotary axis around the corners. The only time it becomes a full 4 axis move is when wrapping around corners. (think cylindical grinding a square, but plunge roughing instead of z level roughing). This would be done in a VMC.

A vid I took of some programming I did on our Haas Multigrind.



My thinking is that, then, I'm constantly feeding the tool into the workpiece by the helical offset amount.
Anyone here done this with any success? Im trying to do it in Esprit, but its kind of pissing me off, as I dont have the control I want over the toolpath.

Cheers!

This topic about inserts is not a new one I realize but:

I was running some cylinder liners from Darton and the roughing insert lasted 2 parts if I am kind to it. Sparks started flying on the 2nd part. On the start of 3rd part the edge were gone. Should maybe have turned the insert after the first part.
I was running this dry (not doing that again) with a Sandvik CNMG insert for cast iron. I ran about what it said on the box.
150m/min ~500sfm
1mm Ap ~.040"
0,2mm feed ~8thou
The roughing took about 7min, so that is how long the insert was good.
The reason for the shallow cut - Said 1mm on the box and I was worried about the part slipping. Probably not a problem since it did not spin even when the edge had gone.
So: Any good ideas for increasing tool life besides running coolant ? And how much does coolant help in cast ?

How do you make sure that your fancy CNC machines is pumping out good parts?

If you have 2 to 4 guys on the floor and none of them are a dedicated inspector, customers constantly calling about delivery....

Who checks who?

Hi,

For lights out machining, and large programs over an weekend, I'm interested in what systems is out there?

So I figured I would buy some carbide drills just to get used to them a little before the speedio shows up. 25/64 (.3906) 5X 3flute MA Ford series 229 drill designed for aluminum. I set it up in the Fadal, modify the program to the speeds and feeds it tells me but I'm a little cautious. So I run it at 700SFM as stated and rather than .014IPR, I do it at .010 and even add a peck every .50 just to make sure. Hole is only going to be 1.03 thru, but I like to be safe on a spendy drill.

It squeaked a little going in but drilled the hole ok, I figured ok, maybe the chip load needs to be the .012 minimum to better break the chip for clearance. I bump it up to that speed, drill my hole and shatter $78 in nothing flat. I'm so mad I look up the drill data, yup, its good, call up the distributor and :mad5: just get started on my rant when I notice that I programed it for .012 chip load PER TOOTH! :eek: I just told him, yeah, so do you have any more of those on the shelf?

The amazing part is that damn drill did about 10 holes at .030 per rev before I bounced it up to .036 per rev.

Sigh. 30 years machining and fail to notice IPR or IPT. I need a drink

Keeping it grounded here boys!

Seems the oil cup on top of the spindle for the drawbar/pneumatic thing, hasn't used a drop of oil for as long as I've had this machine. Same for the one at the back of the machine from the looks of it.
Any of you guys with a Sharp 2412 notice the same? is that normal?
I'm doing a big cleaning and maintenance on it now, trying to figure out every stop that might need oil/grease and what not. Never really gave it anything other than way oil.
Anything I need to oil inside the carousel? can't find any fittings on that, just gonna throw some grease on the cogs thing for indexing it.


thanks

Our Alpha 550 keeps giving us a spindle fault error, preventing us from turning the spindle on. This has been an issue in the past, but we could always just restart the machine to clear the alarm, but it's finally reached a point where we can't get away with that and it's preventing us from getting work done.

Has anybody had any experience with this machines or had similar issues?

I have a Haas VF4 with gearbox in our job shop setting. There are days that it will get run all day long, and other times that it wont get ran for a few days. I run Haas' spindle warmup, but am curious to see what everyone does for the ways. I remember seeing someone running X Y and Z in their spindle warmup, but come up dry on the search.

I figured making up a warmup program for the ways wouldn't hurt my situation, but looking for some suggestions how to run it

As on the below Brother drill tap center. Note the black "joystick" control to the lower left of the hand pendant MPG. This opens and closes the collet device on the Nikken 5 axis trunion rotary table. I have seen other Brothers where the same thing was accomplished by electric push buttons located in the blank plate below the control. That seems so much "neater"....with the tubing not hanging down in front, etc.

What would I need to convert this one to electric control ? I presume the two N/O push buttons and an electric peumatic solenoid of the same function as the manual one....guess the main PITA would be finding voltage source and running the wires to operate it and presume the actual solenoid would need to be located remote so the potentially oily exhaust air would not matter too much ?

Thoughts ?

Hi guys,

I have 16K RPM spindle. I have a high-quantity production job which has .125", .140", and .238" holes. I've noticed in some folks's programs that they don't run smaller drills at top speed. Just wondering if that's SOP, or just being cautious, or no reason at all? I have 10k parts to run, so am looking to squeeze every second out of the runtime. Right now I'm using Guhring 659's for the smaller holes, and OSG EX-Gold for the bigger hole.

Thanks, and regards.

Mike

We had a Hyundai lathe problem that required replacing some Siemens hardware and reloading the machine files.(NC, PLC and HMI) Files that we had archived on the hard drive in 2010. They contained all the data currently loaded, so I never thought to make new copies.

After the reload, we noticed a bunch of problems with machine offsets, tool table and incorrect spindle speeds.

Hmm...... Maybe the didn't reload properly. Try again.... Nope, still bad data. Somehow those old files got corrupted.:cryin:
Luckily, I have another lathe I could create and transfer all the files I needed to get me back up and running.

I get a lot of help from everyone here and usually don't have much to contribute. So I'm just sending out a reminder in case you haven't done it recently.

Thanks
