I have a 1995 Fanuc Robodrill T10B with 16mb controls. It has a 8.4" LCD that has issues. When I turn on the machine the right side of the screen is pink. The left side looks good. After 5 min or so the right side starts to show text but flickers allot. Another couple minutes and the screen evens out mostly. There is a distinct shading down the middle of the screen and the right side is slightly blurry. Sometimes the Right stays pink. Sometimes it turns black like the left side. Any suggestion of what to look at and how to fix? I re-seated all the cables. The soft buttons seem to work. All seven main screens work. Just the display is wonky. Is it the LCD or the Card above it? Or both? I just sank every penny getting the machine home. I don't have $1000 to change a screen.
I have seen some old posts of people upgrading there old CRTs to LCDs. Is there a cheap way to do this?

Dowel holes reamer or interpolation?

Hello

Thank you for reading my question

I would like to know what is your preferred method to drill dowel holes

On the job I am machining now I have 2 blind dowel holes Ø3 x 8mm deep on aluminium

The tolerance about positioning, is not stated on the drawing, we only have a general tolerance box in which it states +-0.1

These 2 holes are not aligned and they are also on 2 different heights (surfaces) one is about 5 mm higher than the other

Since we do not have a proper tolerance on the positioning, I think these 2 holes are independently from one to an other, I mean I do not think we have a part that fit on it, with the same holes positioning, but this is only my guesswork (deduction).

In my company they always interpolate this kind of dowel holes with a 2.5mm carbide slot-mill, and we drill it 2.8 first, even on holes deeper than 8mm, the reason why they do in this way is because they are worried that with the reamer we will not get the right position.
What is your preferred method to drill dowel holes?

I did drill the same kind of dowel holes, on a steel 14mm deep through.

Even in this case they had programmed with interpolation with 2.5mm slot-mill, and I decided to do it with the reamer instead, and it worked very well, and in this case we also had a proper tolerance on the positioning, 0.02mm circular rad.

I think if you check the run-out of the spot-drill and the reamer, regarding the drill even though it will not run very through, should be ok, since it will follow the spot-drill.

And also make sure the spindle inside and the holders are properly clean, with the reamer should always be ok to machine this kind of dowel holes.
What sort of holders do you use for the spot-drill? Do you use collets?

What sort of run-out would you consider ok to machine this kind of holes?

Any suggestion according this matter will very appreciative

Thank you in advance for your help

I have a Warner Swasey WSC-12 2 axis lathe with Fanuc 11T controls. All functions appear to be working fine except I can not get the spindle to turn, even with the jog button. I get no warnings or error alarms/codes. When I push the jog button, I can hear the clutch. It has a Reliance Spindle Drive. Any ideas what I should check??

Hi frinds,

Look, i have ELB Flachschleifmaschine, old machine and i dont need it anymore, but they have great magnet which i need on my CNC machine to work with it. So, i remove magnet from Surface grinding Machine but still i need AMPLIFIER from ELB machine.

Has anyone know where on the photo is AMPLIFIER for this magnet?

I cant recognize AMPLIFIER in ELB machine.

Ok, thats my idea couse magnet cant work without amplifier thats right.

If someone know how, or have better idea please writte and i appreciate that...

Thanks all!!!

Despite putting in 60-70 hours a week for the past few months I have been trying to study a little macro programming even if it's only a few pages a night.

One of the sections covers the use of a macro for setting work offsets ( user defined with a G10 + P address) that has caught my eye. I have often wondered how work offsets were handles in situations such as a horizontal machine with a pallet pool where when one pallet was loaded with a dedicated fixture if it was probed before machining or if the work offsets were stored in the program or a combination of both for verification.

We have 5 double vises that are located to a sub plate on 7.5" spacing and use dedicated soft jaws that are pined to the vises for location before cutting to insure repeatability when the job is run again at a later date.

I could see where including a macro to define the work offsets would be advantages but wondering if this is a common practice?

I am new to VMC's and new To Fanuc. So this has been harder than I though trying to get the machine to do something. I was able to load tools. Setup the tool library, populate the magazine, jog axis's and turn on and off the spindle and coolent. I have the Fanuc Manuals for the control but not for the Robodrill itself.
I tried to use the Super Cap (conversational) screen to create a tool path. I can't find the screen. It says step 1 enter edit mode. I don't have a edit button anywhere hard or soft. How do I get there? I found a Quick Cap soft button but following along in the 16mb manual for Super Cap I am missing buttons. I have one for drill but not for mill or face. On a similar note I tried to load a endmill and it said no its not a drill. Is there a parameter that locks out all milling operations? There were endmills in the tool library. And there were programs in the list that specified endmills.
There also is no MDI button. How do I get to the mdi screen to enter short programs and m codes?

Maybe there buttons are there and my wonky screen is preventing me from seeing them (see another post) but I don't think so. Its like something is locked out.

Does anyone happen to know where the mains input voltage is measured?

The control system is Fanuc OT.

The machine declined to power up over the weekend, complaining of excessive mains input volts. There are two connections options;- 220v and 230v. It is currently connected to the higher and there are no taps on the input isolation transformer.

It will switch on at 240v phase to neutral but not at 241.

There could be a VSR or the measurement could be electronic. I can find no clues in the circuit diagrams.

I have an adjustable angle live tool for our Doosan lathe. I've never used it before and now have an upcoming job where I'll need it.

The part has some flat bottom 5mm holes at 35° to the Z axis and I'll be doing them on the sub spindle. The holes are located on a taper and are dimensioned to the intersection of the axis of the hole and the surface of the taper.

Those of you that use these, how do you set your X and Z offsets?

TIA, Gregor

I've heard these wear out. Is this true? Seems to me they are fairly simple piece of metal and would last a very long time if not damaged. DO you have to replace these periodically due to normal use? Thanks

I'm getting fed up with trying to keep chips out of my coolant tanks. I have two machines that came with LNS turbo HB conveyors. We are mostly doing aluminum and fines are getting into my tank.

On the first machine I rigged up an air blow off, which works but creates more mist than I want. Now with the second, I am brainstorming some kind of rolling brush to kick the chips that stick past where they should fall.

If I knew of a system I could add to the existing units I would happily spend for it as my time is worth more than rigging brushes to conveyors. Anyone have any leads?

New to the forum and I've found this site very useful for years. First off I'm not a programmer by trade but have been thrown into the role since our engineers at my workplace don't contribute much in this aspect of my job in Maintenance and we don't have a cam program for our cnc lathes. We have a pretty extensive set of duties here including full machining, electrical, repair, building etc. You name it we have to have some knowledge in it.

I've read every post here concerning G76 code programming for my machine which has a Fanuc 21i-TB control. I'll list the program and what it does. I'm trying to turn 1/2-20 threads and I have self taught myself on this machine so far. It's done everything I've programed with other repetitive canned cycles but just won't thread on this portion . Here's what I've got in the part of the program where it stops on 2nd line of G76 and just sits there doing nothing:


N340 T0909
N350 G97 S800 M04
N360 G0 X.550
N370 G76 P020060 Q0050 R.0005
N380 G76 X.404 Z-.90 P0100 Q0472 F.0769
N390 G1X5.0 F.150
N400 M30

It just seems like the machine is waiting for more information as it sits at the starting point of where the threading starts. In running the simulation it appears to only run 2 passes in the threading portion but it does show it threading. Everything else in this program works fine.

Any input or help would be greatly appreciated as I've exhausted every means. Thanks again for this great site!

Hello everybody!

Can you please advise me with this problem I have with my Takisawa MAC V1E from 1990 equipped with a Fanuc O-MC steering?
The following program runs nice but stops after the M29 S400 M03 command (the spil is spinning then):

(Rigid tapping M6, 6 times)

O3004
G17 G21 G40 G49 G80 G94
M06 T08
G90
G54
G00 X-15. Y-15.
G43 H08 Z5.0
/M08
G01 X5.0 Y25.0 F600
G59
M29 S400 M03
G84 G99 R3.0 Z-12.0 F1
Y50.0
Y75.0
X95.0
Y50.0
Y25.0
G80 G94
G00 Z250. M09
G91 G28 X0. Y0. Z0. M05
M30
%

I must do a reset and the machine will not go on with a new program because error 44 PS alarm is in its way.
G80 en M30 manually given solves this.

Parameter 256=29. So OK for M29.

Any help is very welcome!!!
Thanks, Leo

We have a Star SR20 R. We are a microprecision custom job shop that runs small runs at relatively high speeds. Utilize various materials, brass, steels, aluminum, etc. and most of our parts are the held to a quarter of the size of a pinky finger nail (to give a visual) with very tight tolerances, so the 'lid' on the Star gets opened and closed a lot during a run.

We are new to the CNC world and, normally, due to the specialized nature of parts we are asked to produce and smaller quantities we run have no problem with oil mist. However, on larger quantities (10,000 up) we are experiencing the 'fog' from oil mist. We use Hangs Missle Lube-so the stuff is pretty safe from what we have read.

However, we are exploring mist collectors of various types from electrostatic like Tri Mist, centrifugal like Royal and a relative 'newbie' 3nine which uses 'disk stack-centrifugal' type of technology.

The costs of these things are all over the map from about $2,900 for an electrostatic to about $8,000 including install on the 3nine "Lina" type unit that seems to be newest on the marktet.

Have listened to the various salesmen and want to know what experiences there are in the actual use in the field by folks who have been there and done that and know what true operation and effect on the production floor is with these things and what actually works or doesn't. Do you 'really' get what you pay for and what really seems to work? $8,000+ for a mist collector seems like a lot--no?

Thanks, in advance, for any advice/feedback.

Hi guys,

I'm looking for a round-shank (with flats) toolholder that holds VNMG inserts "straight in". Like a face grooving tool for making angled face grooves. Looked through Kennametal's site but didn't find anything.

I have a regular PH Horn face grooving tool but the part I'm quoting has a large but shallow angled-sides face groove, in 304, and my face grooving tool's inserts are pretty spendy so am looking for something that uses commodity inserts. Side clearance might be an issue but I can relieve VNMG inserts pretty easily. Groove large diameter is ~2".

Thanks, and regards.

Mike

Hey guys,

Quick question about Haas Setting 8 which locks out program memory. If this is enabled, you cannot lock programs, but are you able to modify work-sets (G54, G55, etc)? I am looking for a way to lock-out the actual program, but still allow the operator to make adjustments for the work-sets.

Thanks,

Brandan

When loading a program off of a USB, on some programs but not all, I will get a message on screen when trying to "F Get" that reads "DISABLE TO SELECT". I can switch the input over to RS232 and load the exact same program without any issue. Like I said it doesn't happen too often but I can't find anything in the book or online that says anything about the message so any information on what the machine isn't liking would be appreciated.

Hello all,

I have a problem with my Sabre 750 with Acramatic 850 control.

Yesterday when I turned the machine on, all the leds and driver started but no display, I restarted the machine several times but the display did not work.

My display is de ambar monochromatic so the back of the monitor does not have a normal VGA conector for me to use.

Would a XVGA BOX work?

If anyone has another idea or something I should check first please let me know.

Hey guys im hoping someone out there has experience with fabricating retaining/spring clips. We recently had a retaining clip produced for us with a waterjet due to its odd geometry. We called for the clip to be made out of carbon steel and requested our vendor, who is experienced with this kind of stuff, to please let us know what kind of steel is best for the job. .
They did not do that. Instead they cut 200 pcs that when squeezed completely deform in your hand. So after doing some research it looks like we should be using C1074 high carbon spring steel. But then I got to thinking, is possible its not only the material but also the process. Im wondering if its even possible to cut these or do clips like this have to be formed, and is it necessary for hardening/annealing for it to retain these properties. i can provide a picture of the uncommon geometry if that helps anything.
Any insight is appreciated
Thanks in advance

I am new to the Okuma control and cnc lathe programming period. I have an Okuma Cadet I am learning on. I was trying to strip down another simple program that used 1.5" material to make what looks like a little top hat plug. It uses the built in Lap cycle for roughing and finishing.

I tried to strip it down to the bare bones and only use the roughing. I didnt even get as far as adding the part off yet. But here is my error.
