My slant bed CNC

poppy_au · Dec 30, 2016

Hi
Here are some screen shots of my slant bed CNC lathe. The design I have taken a bit here and there that I have found around.
The spindel is turned from a 120 mm solid bar. Spindel bearings are double angular contact bearings on chuck side and deep grove ball bearings on drive end.
Frame plates are 20mm, ribs are 15 mm. All screwed together. No welding in order to avoid stress and tension.
Rails are 20 mm and ball screws are 16 mm with 5 mm pitch.
Motors x and y are NEMA 32 direct coupled to ball screws.
Base are made of 80 mm alu profiles.

Boring spindel frame plate om my X3 mill

poppy_au · Dec 30, 2016

Milling and treading the frame ribs. This is the limit that my X3 mill can handle. Sorry the photos came in upside down. How do I correct this?

Milling motor bracket. Got an SEW servomotor with gearbox from ebay.

Frame assembled.

Auto tool change housing, index plate and toolholder. This has been one of the most interesting design and machining tasks I have done.
I took my toolmaker training back late 60ths but have not practice machining since I got my hobby late and mill about 6-7 year ago. I really enjoy, figuring, designing and then machining. First i used Autodesk Inventor in design but this year I switched over to Fusion 360 that I just love.

Very nice, I shall be following this but can a moderator please rotate the pictures please ?

Very impressive. I'm finishing off a scratch build CNC plasma cutter that has been going on since June. The last pieces turned up yesterday and I hope to have files to my laser cutters next week.

Interesting stuff.

As for the pictures, I assume you're using an iPad or iPhone which are real sticklers for being the right way 'up' when taking photos. They're difficult to fix after you've taken them but when you initially take them have the 'home' button on the device to the right (if shooting landscape) or the bottom (if shooting portrait). Then they should 'stick' when you rotate them.

great build thread. looking forward to see this beast up and running.

been trying to put one together me self over the last few years, been having problems when it comes to the base of the lathe.. as in the bit you put your Z rails on. not so much problem but going over the options.

what have you used for yours?

DICKEYBIRD · Dec 30, 2016

Wow, tackling a lathe build and a toolchange turret. You da' man!

Let me guess...LinuxCNC too, right?

poppy_au · Dec 30, 2016

Yes, the photos are taken by ipad and iphone. If I can do anything before posting? They are ok when I view them.
I am going to run it by windows and Mach3 that I have been using on my combined cnc router/3D printer that I made before I started on the lathe.

Thank goodness for that! Us Mach3 lathe operators have to stick together.:thumbup:

poppy_au · Dec 30, 2016

I am very happy with Mach3.

Here are some more of my twisted photos:fan:
To get the center hight right I found it was easier to make the tool holder my self.

I'm starting to power up the machine. One of the stepper motor drives did not work. It's the one for the ACT turret. It's a Wantai DQ860MA stepper drive. Tried everything switching wires and drives from the other two axis but it is obvious that there are something wrong with the drive. But when I contacted the suppler they came back and told me they are sending a new one right away. Good service. I bought it from "Lucky Shop-Caroline" via AliExpress.
Than I tried to fire up the SEW Movidrive and the SEW servo motor but this I gave up. I got one Vacon NSX 12A drive instead and this was a piece of cake to set up so now the spindle, X and Z axis are running. Just need to connect the signals between the VFD and the BOB and couple the motors to the ball screws, than I'm ready to make some chips.
Still got to get the ATC turret macro made and the new stepper drive. Then cover the rails etc.

Ooops, I started out on LinuxCNC with a Mesa ethernet card. :fan:
