I am a newb to the world of CNC machining so forgive my ignorance, but I want to know if a 4-axis CMC mill can essentially do the equivocal operations of a CNC lathe? What is confusing me is that the "4th-axis" is a rotary table head and tail stock that sits on the mill table, so does this mean then that you have the capability of turning operations with it? I mean aside from the fact that the tool bit of a lathe and the end mills of a vertical mill sit in different places relative to the stock, isn’t the basic motion created by the rotary table identical to that of a lathe thus making turning operations at the least similar if not identical?

Yes, of course, if its set up to do it.

I am a Machininst by trade. I know about CNC, but I don’t have much to do with them. I am running a manual machine shop, no CNCs in it.

But, you actually don’t need the 4th axis to turn something like you would on a lathe.

Since the Z axis, the one coming down on the part is turning, you can make that turning bit turn in ways that turn the outside of a piece much the same way you would turn a piece in a lathe. The piece that your turning would need to be in a vise and mounted like any other piece, but the work could not be longer than the bit doing the work.

You can also have a collet holding system installed on the bed of the Mill horizontally with point rest on the other side to hold the other side of the piece in place that will turn a piece incrementally, index it. I don’t know if that would be considered the 4th Axis though. Maybe the rotary Table could be considered the 4th Axis too. But, in either case, the piece would need to turn pretty fast to get the same effect as being on a lathe and turning.

You can do internal threading with a single point threading tool in a stationary piece. So that is in a reverse sort of way, using a Mill to do a threading job. Only the piece is stationary, but the bit is doing the work.

It would be a bit cumbersome though, but, yes, it can be done.

Don’t worry about being a newbee. I started in the machining world over 30 years ago. It take years to really get good at it. Sometimes I wish I never got into it, but a guys got to do what a guys got to do:)

Know this is difficult – I was thinking of a CNC lathe or something like it – would it be one ton, two? I need to calculate shipping based on weight – I can visualise the size but not weight

I’m a CNC machinist, hard to say an average, depending on lathe or mill, big or small, I run mazak quik turns, which i think are about 3000 pounds.
I’ve worked on other lathes that were in the 5000 & 6000 range.
I’ve also worked on mills that were 10 – 15000 pounds.
If you know the make and model of the machine, maybe do a google search for the mfg. and check their dimensions and weight.

I was at work, and a co-worker told me for "homework" to come in at tell him why that when using a CNC lathe, when the piece is being cut, that counter-clockwise is "forward" and that clockwise is "reverse".

I think it has something to do with the placement of the cutting tools, but i don’t know much about the CNC lathe, and I’m learning as much as I can about it before I go off to college.

It probably has to do with the way the chuck is attached to the driving mechanism and/or the direction the clamps on the workpiece in the chuck is rotated. Cutting forward puts a torque in the same direction as the chuck and/or clamp so, the piece will not loosen, nor will the chuck itself loosen from the driving mechanism.

For cutting "in" (reverse) the cutting torque is in a direction that would tend to unscrew either the clamp or the whole chuck from the driving mechanism so, there is a small chance either the piece might come loose in the clamp, or the chuck itself might unscrew. If that happens the force on the cutting tool is ‘in’ toward the chuck so, the piece won’t fly out, it will just stay in-place.

www.barpullers.com – This video shows the Royal Grippex Coolant Actuated Bar Puller removing a finished workpiece from the sub-spindle of a multi-tasking lathe. This allows the sub-spindle to swallow long parts, without the use of a parts ejector. Additionally, the Grippex is shown removing a long bar remnant, preventing the bar from dropping into the chip conveyor and potentially causing damage to the conveyor. The Royal Products Grippex Bar Puller for CNC Lathes can be used for both pulling spindle length bars up to 3-1/8″ dia. and removing finished parts from the sub-spindle of a CNC lathe. The Grippex is actuated through coolant pressure of the machines turret or spindle (multi-tasking lathes).

Haas Automation, Inc. donated a CNC lathe to Dunwoody earlier this year. Here’s a quick look at it in action with help from Machining Technology Senior Instructor Brian Nelsen and one of his students (who preferred to remain anonymous). Please note that the shield was left open in order to capture a better view. That’s not standard operating procedure. We don’t recommend running a CNC lathe like that for normal use. And anytime you are doing machining work — wear safety glasses.

I am a CNC machinist. CNC Lathes can be used to produce anything a manual lathe can. This is also true of CNC lathes.
CNC machines are much more economical to use than their manual counterparts (at least for high-volume production) due to their repeatability, their lower per-piece cost, their ability to be left unattended, and their ease of control. Once programmed and debugged, a CNC lathe or mill can theoretically produce millions of identical pieces, provided the cutting tools (Titanium-carbide inserts on tool steel cutting tools) are maintained.
By the way, the lathe is the only tool that can be used to reproduce itself.

Me and my friend are planning to set up a Machine Shop in Mumbai. We dont have much background experience in the field but we are quick learners…..but we are confused over one point. Some have advised us to start off with a small machine shop with a manual lathe and drill machine and build up from there….whereas others claim that manual lathe is old technology so its better to invest in a CNC lathe right away…we have an investment of about 25 – 30 lakhs….any suggestion from you guys will be helpful…thanks

You have to start a strong start, so bring both. If worried about expenses, then start with refurbished CNC

Hi, I was wondering if anyone has replaced the CRT in a CNC MIlling Machine? The screen in my dad’s older Bridgeport CNC fried out today. I read on a forum that you can make about any monochrome CRT work if one fails as long as it will fit into the chassis. We have a CRT assembly from an older Mazak machine that works but is a little dim. The tubes look identical, same size, same orange color display, hookups, etc. It looks like I could just swap out the tube and splice the connector onto the working tube? It’s a very simple tube with no adjustments on the yoke like a projection tv gun would have. Is there anything else I should think of before going for it? My dad is just getting back into machining again, I got the data working to it and a half hour later the CRT went blank but the machine still functions. Anyway, Thank you!!!!!!!!!!!!!!!!!

Well, I worked with Japan CNC lathe before as a technician.There are many factors you have to take care of.

1.Different monitor need different signal although they are CRT type since their control circuit are vary. You should ckeck their signal pin and power requirement for details.

2.Are the two CRTs really same?. I mean the number of display line,etc.

3. Your machine is still functioning while CRT got blank I think this because the display function doesn’t affect the program.

Hope this may help
