Taig CNC Lathe Ideas
Thanks to the contribution by George Moorehead of Gig Harbor, Washington, I see an excellent platform for creating a Taig CNC lathe. My vision is to use mostly Taig components. It is a similar basic idea that other creators have embraced (like Tormach Duality Lathe)* when creating a CNC lathe machine. I am not thinking of the entire lathe, just the head as George has done.
*Tormach seems to be phasing this Duality lathe-on-bed (LOB) product out with preference to their new Slant Bed lathe. At least it is no longer prominent in their product offers. But for the Taig, the lathe head design on the mill table seems like a very practical way to achieve CNC lathe operation.
I have often studied the Taig micro lathe trying to imagineer how to make it a CNC lathe. Many folks have accomplished the task. But George and even Tormach with their new slant bed design have raised a good thinking outside of the box point that a CNC lathe doesn’t have to look like a converted conventional lathe. The head-on-bed (HOB) is a superior approach for Taig components. Of course this has been done by many others, so no originality is claimed or credited to anyone. The Taig factory could be doing it.
My point is any home machinist can do this and thanks to George for getting the juices flowing and blowing away my image of a converted Taig micro lathe.
I have all the major spare parts needed. Even an old style Taig CNC mill head (Non ER) and an A/C mill motor. I just need to design a few mounting plates. I can see that this would also make a great 4th axis with the proper stepper motor.
I am only discussing ideas here. As a dealer,… Continue reading
Seeing The Light
I am showing off my personal Taig Micro-lathe and some of the minor improvements I have made. I haven’t done any super detailing but it seems everyone modifies their Taig Micro-lathe to the way they like it.
It is an older version and NOT exactly the same as the one being sold today. I wrote an article when I first obtained this lathe, so I won’t go into detailed coverage here. The biggest change is the carriage on the new lathes are extruded rather than cast, a much nicer looking detail improvement.
I like the motor on the left rather than behind the micro-lathe. I don’t want swarf thrown all over it and there is the carriage clamp screw on the back side of the carriage I have to get to. The compound tool holder (not shown) sometimes has to stick out the back for angle cuts. Also the motor switch is far more accessible in this position.
I also like how easy it is to make accurate motor belt adjustments. Other owners can do it their own way. The motor base is a homemade copy of one shown in Nick Carter’s web site. I used to buy from Nick (including this lathe) until I became a Taig dealer myself. He is a good guy!
The motor is a Dayton 6XJ07. It was supposed to be TEFC (Totally Enclosed Fan Cooled) but the shaft end cover is open in this motor. I have checked… Continue reading
4 Axis Spruce-up
I have found a good project for my 4 Axis CNC mill and also my Rhino 5 software. If you have read recent posts I have mentioned I am pursuing carving some small bells from wax for lost wax casting. Here I am re-configuring my original Taig micro mill back into 4 axis operation.
I need the tailpost to be able to slide into any length position I need. The stock Taig slotted table is perfect for that. I don’t need the multi hole set-up table for 4-axis. I set the rotary table up so I can just slide the tailpost against the back of its slot and it is in perfect Y alignment. The height is taken care of by the shims and the small adjustment in the tailpost itself. After this set up it will be a very quick reset for the tailpost.
You can see I have placed a Chuck adapter in the middle of the table. I will use that (with a chuck) to hold the wax cylinder as I mill out the center of the bell.
I have a few seconds of video I made of a dry run of the 4-axis profiling run. It makes some interesting sounds as the X axis is moving very slowly and sometimes “jiggling” a bit. Not sure why, but it is playing that CNC music. You will have to imagine all the missing parts. Hey! Just do it! 🙂
Sneak Peek
Here is a sneak peek at a brand new Taig CNC ready mill running some 185 oz/in steppers with a new control I am testing and evaluating. There will be a few updates before I can discuss the new features. Here it is running a 3D carving program at 50 IPM. Short micro moves on the Z axis are creating the crunching sound. Sweet music to a CNCer.
Here is the complete test layout.
Taig CNC Ready Mill
I have a fresh new Taig CNC ready mill as seen in this picture coming into the shop for awhile. I will use it for testing CNC controls. I need to experience setting it up as a new machine owner would.
Most followers of this blog don’t know my original Taig CNC mill is now 30 days from being nine years old! It is still running like new. Maybe better. It’s hard for ME to believe I have been using it for that long.
This new Taig CNC mill should behave exactly like my nine year old Taig mill. I do not expect any surprises. The mill is exactly the same as it was nine years ago. The exception is originally my machine did not have the high speed continuous duty ¼ hp motor.
This is a serious investment in inventory dollars but I sold three Taig mills last month. Sales are good. I also don’t want to tear apart “Old Faithfull” just to test new control systems. I did consider doing that (in a different blog) but I totally like what I have. I have a Smoothstepper built into my home built controller and I was fussing about losing that nice feature. It won’t be included in my recommended package simply for cost reasons, but is highly recommended, even necessary if you don’t have a parallel port on your PC. There will be a different serial adapter available.
So I will have a fully setup and well tested new Taig mill and a functional CNC system I can sell to recoup my investment. Everyone wins!
I could promote the Taig CNC factory package and I may still do that but I am considering something a bit different and I think with more… Continue reading
