Our shop is looking for a new/newish big bore lathe with live tooling and possibly y axis milling capabilities. 32ish inch air chuck, 13ish spindle bore and 120ish z length. We will need a steady rest or two as well. The top 3 choices are a mazak quick turn or slant turn 550my, doosan 800l and a hwacheon something or other. Anyone have any suggestions? We are located in Alberta Canada and do a lot of small batch machining/repair work of oilfield components. Big API threads are very common in our shop and we also do a lot of deep boring with devibe bars. Any information on brands or opinions on live tooling with or without y axis capabilities would be appreciated.

Frontier L missing threading macro

Hello, first post but have gained lots of help over the years in covered topics. We have a 1994 Mori Seiki Frontier lathe with the MSC 521 control. Apparently this control used a macro program to thread in a G76 fashion, which I don't understand since the T6 in 1980 has G76 threading. My problem is the 9000 programs for OD and ID threading are gone from the control.
This machine was purchased used and I remember at the time the dealer it came from had a issue getting running because of dead batteries, so that's probably when these macros were lost. we have only ever used it as a second operation machine where threading wasn't needed until this week.
I know I still have G92 and that's not a problem, I would just like to have the simplicity of the single line threading, If anyone has the macro programs 9207 and 9208 would be greatly appreciated. Thanks, Steve

As the title says, a copy of the programming manual and parameter listings, etc. About 300+ double sided pages covering all you need to know to run the machine.

This was copied 20 years ago at Kinkos, the receipt says $45 + tax. Today's price is $60 OBO + shipping, that's what Office Depot said it'd cost to copy now.

One copy only available, I'm not interested in getting into the manual sales business. This is a copy I overlooked when I sold my other copy a few years ago.

PM if interested.

Thanks for looking.

I am new to using a VMC and rigid taping and so far the holes I have tapped have been fairly shallow one diameter in thickness. I have a part I am getting ready to program some 1/4" - 20 holes in a 1" thick part the threads will be blind and I want to thread in .500". Should I peck this once or do it in one pass. The material is 6061 T6 the machine has flood coolant. I have been taping my shallow holes at 1000 RPM.
Thanks Mike

Tool changer will not move to spindle
This happens just out of the blue. The machine will be running fine and it show this error. You can let the machine set for a while or continue running it with a manual tool change and it will start working again. I have changed the card out that controls this function, can't locate the problem.

I am ready to pull my hair out. I have been fighting with this for a week.:angry:
I have the cable configured like this:
http://www.machinetoolhelp.com/_Imag...le-pin-out.jpg
I am trying to use NC lite to back up my parameters. I don't get an error on the control. it is flashing "output" The Program gives me a Ack1.err instead of receiving the file and I don't see anything about that in the help. I have tested the computers com port with a loop back connector and it is working. I bought the little Rs232 tester and I have green lights RTS and CTS on the control side, and green light of TXD on the PC side which
seems wrong. The txd side never goes out. For f's sake there are only three wires involved here, how can it be so f'd up?. Ive tried selecting software handshaking and no handshaking. I get the same ack1.err either way 2400 baud 7 bits data 2 stop bits, even, and I think everything is right on the control 232 parameters.

Brother A00 control disabling the 4th axis

Recently I bought a 2006 Brother TC-S2B with a A00 controller. It originally had a 4th axis attached but they took it off before selling it to me. I got everything powered up and I'm getting a 5063. 18 **A Servo (CSE) alarm. I'm assuming that its from the 4th axis being disconnected. I believe I can disable the 4th axis through the Machine parameters. I read in the forum rules that there are to be no machine parameters on the public forum can someone PM me the procedure to unlock the machine parameters.

Thank you for reading any help would be greatly apricated.

Robodrill troubleshooting: first start up

Hey guys,

We just got our 2004 Fanuc Robodrill T21iBL to power up today: used an American Rotary panel to make a converter, which seems to work fine. Otherwise, I have a few error messages that I’m having some trouble troubleshooting.

I only have the operators manual, and I probably wouldn’t make too much head way on this by myself, even with a mAintenance manual.

First alarm: 1003 emergency stop. The E-stop isn’t pressed in, and I heard someone mentioned on another thread that it could be thermal overloading. Thing is, I haven’t moved any of the axes, and we just turned it on today.
.

Next is a door lock alarm: 2001. We closed the door and even locked the button in place, but we still get this alarm. This might just be me needing to figure out how this door lock was set up in the software.

2002 is that air pressure is low: every time I go to hook up the air, 100% of it spits out the other end of a solenoid. No clue why this is. My only theory is that maybe we need another regulator keeping it at 90psi, but it has a regulator so I still think it’s something t else.

Please let me know if you’ve seen any of these simple issues, as more than likely it’s operator error.

What is a "2-part system program"?

This is on a Mitsubishi LT-350 lathe with Navi conversational programming. The manual is telling me how to do it, but not why we're doing it... and I'm not certain. I'm thinking it's a M00 where you would flip the part around, but there are parts that I don't get like why is the 1st and 2nd part kind of woven together instead of 1st part and then 2nd part. I'm just confusing myself more...


Thanks,

Bought my first mill! Supermax YCM-30 with Anilam 5000m controller

I just purchased my first mill, a Supermax YCM-30 3-axis CNC mill with an Anilam 5000m retrofitted controller. It also has a 24-spot automatic tool changer on it.

Does anyone know much about this model? Any information/opinions are much appreciated.

I'm confident I can wire the machine up with a VFD and get it running no problem. I don't foresee the need for the 24-spot automatic tool changer, so I will likely remove that and sell it to recoup some of the money I spent on the mill (and buy vise/tooling/etc) any idea what that would be worth?? I will need to wait till I get it home to get more info about the tool changer.

I bought it from the local University's engineering department. It does not look like it's seem much use, the instructor told me they really only cut wood with it. He said he got tired of the students ramming endmills into steel in rapid mode so he would make them machine all their projects out of 2x4s.

This is my first mill, so I'm fairly excited. This is for hobbyist use in my at-home shop. I have not moved the mill yet (will probably pay to have it moved, unless it's crazy expensive)

I have a little experience running Bridgeports and ProtoTraks about 15 years ago, but that's about it. I'm excited to get started, any recommendations on CAD/CAM software?

Thanks for any help you may provide!

We are looking into high feed cutters for our CNC mills.

Just wanted to get feedback from guys who have experience with atleast 2 or all 3 of these brands.


1. Dijet SKS (3 edge insert type)
2. Sandvik R419 [ R210 takes up too much power in some machines and is harsh in our experience ]
3. Walter F4030

We mostly cut AISI 4140 80ksi or 4330V (30Hrc). Machines vary from 40 taper to 50 taper machines.. will put 1.5" or 2" cutters in the 40 taper and 2.5 or 3" cutters in the 50 taper machines.

Need to select one of the 3 above.

Thanks.

I'm looking for a way to speed up finishing post machining in my one-man shop. I currently put a scotch-brite finish on my product line and am happy with the look, but need something faster. I've been considering a tumbler. But what sort of finish can I expect? I'm hoping for a satin look and not a dull galvanized look. I'm working with aluminum in this instance.

Tool path stopping short

I have a part that I'm running a trace tool path to engrave some lettering on a part. It simulates fine in Fusion, but on the part, it's stopping just short of finishing the path- maybe .005". I don't have an optical comparitor, but with ye olde' naked eye, the tip of the tool looks fine. I can't think of why it'd be stopping short and not finishing each character.

CNC Milling Renshape for the first time ever..

March 18, 2019, 9:59 am

We have just begun a huge project using Renshape material. I've never used this before but all the research I've done tells me to be ready for a mess. That's fine and we are ready to deal with that but I have some other concerns..

The job is mostly 3d milling which is no problem to program but holding the parts will get tough I think. There aren't many square edges to them so holding them in a vise for the most part won't be possible. My plan is to use helicoil inserts to hold the pieces down to a fixture plate so I can machine the 3d contours along the top of the part while also being able to mill the outside shape in the same process. The parts range from 4x4x6 to 36x18x6 so some would require more construction holes than others of course. I've used helicoils to hold down plastic many times with success but being that I have never used this material before I'm worried that they will just pull right out and leave me in a pickle. I also am not sure if I can get away with using a 4 flute end mill to do my rough milling with. Any thoughts on tooling + workholding would be greatly appreciated. Thanks.

Aluminum 6061 T6, thin wall part, rough, heat treat, then finish...?

We have a part that has a machined slot feature on the inside and some features on the outside that result in a thin wall. The specifications on the wall are tight in flatness and we are concerned that stress will warp the thin walls. I understand that a rough machine close, ~.050", to final dimensions, then a stress relieve heat treatment, then a final machine to dimension is the best way to proceed.

Any comments on this method?

My problem: My NL2000 with the MSX-850 control will error out due to interference on blocks 100 and 110.
And yet, a Duraturn with the Oi-Tc or a Haas will run it fine and produces the expected results.

The tool nose is set to Dir 3, and the Nose-R is .0156 in all cases.

The above code is good, and I have finished my parts ( with some finesse ) so this is more for a research and figure out what I can do to
perhaps change some of the parameters on the Mits so it will work as expected.
Please note that even though the geometry is dancing on the razor's edge that's possible with a .0156 rad tool, it IS IN FACT possible and solvable!
The Fanuc does it, Haas does it, I don't see any reason why a Mits shouldn't!
