The spindle is made in Russia by my friend. It cost about 500$. There is no necessary to build such spindle today, you can easily purchase it on Aliexpress for the same cost.
The casting was made on the foundry using my drawings. This is not a problem for me.
Spindle servo rated to 3000 RPM and i am planning to use pulleys 1 to 1.5 to increase the RPM at least to 4500.
Building a new head from cast iron to replace aluminum one. Also want to replace spindle motor and use 1.8 kilowatt AC servo.
Correct.
Actual view of the mill. Working 8 hours per day for 2.5 years.
Electrical cabinet, telescoping way covers and some movement...

Any news to the mill?
Some hand scraping were done to ensure good contact between column and the base. Chip tray welded from 2mm thick hot rolled steel. Pretty tough thing...
Add Z shaped grooves to the saddle for...
Any progress?
Next, i made motor mounts for X and Y axis. They are similar.
Installing ballscrew inside the column and motor plate on top of the column. I am using NEMA 34 steppers with encoders for all axis.
I am living in Barnaul, not far from Novosibirsk. Not very big town in Western Siberia.
Once the dovetails were gone, i decided to make new spindle head, because the original one was too heavy (85 kilograms!) and it has Morse taper #4 spindle, which is very poor for continous working on...
Actually, your build inspired me to purchase this mill and upgrade it. If my experience will be useful to you, it will be great!
I used the vertical slide from spindle head as a lapping plate....
Hello. I decided to share my cnc conversion project of TM 7045 FG mill. This milling machine is a clone of ZAY 7045, RF 45 and so on.
The dovetails on the column was poor quality, so i decided to...
Could you tell us more about Mach 3 settings?
Install some kind of BT 30 spindle with timing pulley and servo motor to rotate it. Much, much better choise for reasonable money.
Are you serious? After all that work you will cut with crapy chinese spindle?
On my TC-229 I can change the language by setting special parameter. Download a manual for tc-215/225, you will find there instructions.
Hello. Bought this machine not so long ago. Can not find any manual/guide for it. There is a problem with Z axis, i need to grid shift it. But how to do it without manual? Anybody can help with it?
The best way to grind taper is to grind it on its own bearings. May be it will be necessary to regrind taper after assembling.
Most of them have 90mm OD.
Are you sure you want to do it by yourself? May be the best way is to find real OD/ID grinder?
Do you really need 4 bearings on front end? What stiffness are you planning?
Why are you using cylindrical ways instead of linear rails? The base of the machine have good rigidity, but unsupported, thin ways destroy it totally.
Something new to the ATC? Want to follow your experience and build one. This is my mill.
Great thread! What's new to the machine?
Where all photos gone?
