I have a customer I do work for getting his manufacturing systems set up. The parts are primarily milled out of 39" long pieces of square aluminum tube. The current machine is a milling spindle attached to his ShopSabre plasma table. It works, but it's a pain. I'd like to convince him to upgrade to a better machine for the milling operations.

The guy operating this isn't a machinist. He has a list of instructions and follows them: Press home button, wait, press tool length button, wait, put parts in fixture, open the g-code file, hit the green button, wait.

Requirements:
40" of X
toolholders (e.g. CAT) instead of collets
mist coolant, although that's easy to add
home switches or absolute encoders
2.5D CNC

Would be nice:
ATC
20"+ of Y
high speed spindle
small footprint

My list so far:

Prototrak: doesn't have home switches on the toolroom mills, so they're out. Their VMC has home switches, but for the money I could get a far better machine.

Haas TM-2P or TM-3P: Probably the least expensive option. Good support

Fryer MB or MC series: Siemens 828 w/ absolute encoders.

Are there any other machines that should be on my list?

In the ideal world, he'd have a mill that took in 24' tubes at one end and spat out finished parts cut to length at the other end, but that's an expensive proposition.

I have a 1985 Dawoo Puma 6s that I finally have up and running. I am trying to get it to chamfer corners or radius and am lost on what I am missing. I have posted what I wrote hoping someone can tell me what I'm missing. In this one I am trying a .01 rad. I found a M code for M76 and M77 for chamfering. I have tried inserting m76 and 77s also with C for chamfering but still cant get it to work. Any help would be greatly appreciated

I recently purchased a 96 Cincinnati Arrow 500 VMC. I got it all hooked up to power and turn the disconnect on and everything boots up ok but when I go to turn on the machine with the power button on the controller it throws alarm 39-11 Air pressure failure. I have air going to the machine and what I would think would be enough air and I can hear air coming out of the spindle. I am just at a loss as to what to do. I am not a machine tech by any means. Any help would be appreciated.

Anyone have any experience with placing a sheet of something between your part and vacuum table to allow you to machine thru the part completely and not machine my vacuum fixture? I recall seeing some sacrificial material that allowed vacuum to "go thru" it but a search has turned up nothing. Or does anyone have any other tips or tricks?

A close friend has a background developing UI's and controls for presses, welders and other misc. He's running out of stuff to do at home while collecting a paycheck not to work. He's asked if there's anything he could help me with, automation-wise, in my shop.

I figured the work he does would use some fancy components, but as we discuss projects everything he does is using a Raspberry PI based UI and Arduino/ China steppers for the process. None of this is hobby stuff. Big manufacturer and some serious equipment.

Anyone else running real industrial automation based on ultra low cost open source hobby parts?

I'm trying to steer him in the direction of an ultra versatile, compact, intuitive UI in a bulletproof housing that we can adapt to anything in the shop- From a single axis back gauge controller to an auto bandsaw control, air compressor VFD control, gantry load/ 3 axis robot arm control.

I know this stuff is big discussion on other sites, but I struggle to wade through the arm chair hobbyist BS. Usually when I read "which size steppers do I...." I know it's a shitshow and I can skip it.

Just after anyone’s input that may have experience on a Fanuc 3T. The machine is functioning well. Only problem is I have no MPG handwheel function in the Z axis. X axis MPG is fine.
I’ve got the panel off the back and it appears clean in the switches. Is there a fuse for the MPG function for each axis ?

Thank you
Dave

Hey folks,

I have a new shop and new machine thread a-brewing. Good times.

What do you want to see? What gets your coffee started in the morning in such a thread? Easy enough to throw up a few photos of a clean new place but I'd love to put in content that people actually would be interested in.

All,

Have a look at the following picture from a test I ran last night on my old YCM-30 CNC mill (Allen Bradley 8400MP control). My test part includes a 2.900" diameter boss type of feature. As you can see, most of the variance occurs in the Y axis (2.906) and diagonal (2.909). The 2.909 is the most puzzling to me. Obviously these are not great numbers. I suspect backlash is the issue. What are your thoughts? If you think it's backlash as well, what's the best way to measure it?

Also, the drilled holes were already in the chunk of aluminum I used as my test block.

The X axis exceeds the travel in the negative direction in the program below. I am new to CNC turning & Fanuc controllers and need some input from the brains here

Recently acquired 1996 Hwacheon Hi Eco 10 w/Fanuc 0T-C (only has G50; can't get to a G54 page and old programs in memory use G50). It has a tool setter that was disconnected from hydraulics and 24VDC. I reconnected the 24VDC and moved the arm down manually and it seems to work in that the offset page pops up when the arm is down and touching a tool tip sets the geometry values.

I went through the tool geometry setting (at the time the workshift X & Y were both 0) by cutting with tool #1, setting X by pressing M, X (entered measured diameter), input (those values are around -7 inches). Setting Z offset to zero at the face of the stock for tool #1, then the rest of the tools set X by touching the cut diameter and entering M, Z, diameter,input and Z by entering the value relative to tool#1

Workshift is set to zero for X. Tool#1 brought to the face of the stock and and set for Z workshift

Hello friends, I have a problem with one of my machines, an old Chiron fz 12 S milling machine with sinumerik 810m GA3 and simodrive 610, alarm 7012 started to appear a long time ago (the unit is not ready), I turned off the machine and started again and the fault disappeared until one day it did not disappear and did not work again, when the Z axis and Y axis move uncontrolled for 1 second and in case of emergency, I have changed the Z and Y axis power plate , I have changed Board G0 and everything remains the same, the same fault continues, I change the connectors of the N1 board of the Z axis for the spindle connectors, the Z axis moves while the milling cutter rotates, I have recorded everything on video, the videos are on YouTube, I put the address of the videos, if anyone can help me, I need to start this machine, thanks to all.

Hi, I am new to this forum. I am in the process of replacing bearings in a Haas 50T 7.5K 45 tooth belt drivin Spindle out of a 09 Haas VF7/50. Just got done replacing Spindle bearings in our Toyoda FA-800 Horizontal. which was cool as heck doing so this Haas Spindle I thought would be a piece of cake. My problem with this one is can not get the 45 tooth belt pulley off the top. I do not want to damage it. if damaged and have to buy a new one I will not get core for this Spindle. So I am getting on this forum to see if any of you have replaced bearings in this same style Haas spindle and have had the opportunity to remove this and if so can throw some info my way on how its done. appreciate all input on my issue. thanks

The guy I hot this machine from evidently crashed this lathe on a regular basis. Pulling the turret off was not bad but now I cant figure out how to get to the pins in the curvic coupler. The only way I see is to pull the entire shaft out as one unit with the coupling as a assembly. Does anyone know how this comes apart. Here are the pics of what I have. I think the part I'm pointing at is bolted to the coupler on the back side.

Anyone know where I can get a wiring diagram for an old (1984) Hitachi HT-20 (Green Machine)? Yesterday I popped a fuse (2FU) on the power supply in the control cabinet. Replacing the fuse results in instant loss of the fuse (even with the machine powered down but still hooked to power). This machine didn't come with wiring diagrams, and Cyber Machinery Sales (the only people I know that support this old machine) cannot find a diagram to sell me. I'm waiting on more fuses to start troubleshooting, but it's like shooting in the dark without a diagram.

Thank you

I think the drawbar has become weak on my bp torque cut. I got an error message about it. It feels wimpy when I put the tools in manually it used to really grab them now its kinda soft. is this a major repair or something I can fix

Hello Guys ,

I am here again ,

I have been trying to restore this machine to its running conditions for few months now.

I had several other problems before which I managed to sort out with the help of this forum and a "local" guy, but now, to keep the story short ,

I had to reload all the parameters , which seemed to be ok , I tried today to run the spindle which worked ok too , tried the 1st tool change , everything worked ok up to the point the pot is ready to go up to magazine , but instead just wait there , machine control seemed kind of frozen, for about 20 minutes up to the point I pressed reset then got alarm 2003 atc alarm.

Machine has been sat for a good 4 months now.

Machine is Kitamura Mycenter 1xif with Fanuc 16i control

Any help is of course appreciated.

Many thanks

I'm looking for recommendations on inserts for grooving plastic.

I have some mirror polished razor sharp carbide inserts from seco for turning, I am wondering if anybody uses anything similar for grooving?
I'm always creating interrupted cuts with live tooling for a chip breaker etc, but for the fine finish on grooves I need something sharp.

Aside from a route such as the link, which would make life simple. The grooves are .153" I need to do, I have made thousands of plastic parts, but I'm never as happy with the groove surface finish as I am with the OD finish.
Kit #32 3/4 inch Groover
.125" Cut-off Groover Right Hand

Or is anyone using good carbide ground and polished inserts they can link?

Thanks

A couple times now I have had the alarms 1019 Spindle Defective along with 9083 SPN:S-SPINDLE ERROR (AL-083). Both times I was able to cycle power and was able to continue running. Alarms happened about 3 weeks apart. Now I am getting a 453 Z-AXIS: SPC SOFT DISCONNECT ALARM. This alarm does not clear and returns at power on.

Both of the alarm conditions appear to be encoder related, but I have a hard time believing that the Z-Axis motor and Spindle motor both suddenly have bad encoders. I have double checked the cable connections and they are tight and clean. When the 1019/9083 alarms happened, I neglected to see if the sp drive showed any alarms, but for the 453 alarm it only shows a dash (-).

Can anyone point me in a direction for things to check? Not a whole lot of experience troubleshooting the Robo's.

Thanks!
