Hello,
My name is Yuri and I Sao Paulo - Brazil (with "s" rather than "z") ;). I thank Gerald for creating this wonderful project:cool:. Forum on CNC in Brazil - CNC Guide - http://www.guiacnc.com.br/forum/inde....html#msg61547 :) Some pictures: |
Welcome Yuri!
Looks like you are on your way. Keep us updated with photos, we like photos. :) |
Welcome to this forum Yuri!
I see you are going to have quite a big X dimension: 4400mm [14.4 ft]. What is your Y dimension? |
Good luck with the building of your MM. I like the clean W/Shop and new tools..;)

I am happy and nothing like a beer to accompany :cool: |
Hi Yuri, Looks like you ordered a couple of extra parts?
|
Hi Gerald,
Yes The company that made the cut has a minimum value for the service. Approximately US$ 270.00 :mad: If commit any errors in the solder, can change the play. What did you think of V-Roller chinese :confused: |
V-Roller chinese should be okay.

In the post 9 reads "solder" read welding.
Problem of translation. :eek: |
Yuri,
No problem, I knew what you meant, even up here in Canada! :) |
Hi Heath,
Excuse my poor English :rolleyes: AND YOUR photos? I think it's legend :D |
More pics :)
Now we are going to paint |

Ah, those tubes are at least 3mm thick, but still not thick enough to tighten the M8 screws really tight in a tapped hole. Are you adding something inside? Or, are you going to be careful with the tightening? I think it is okay for strength of the rail joint if the tightening of the screw is at half-tightened . . . . .
|
Yes the bar of steel inside the tube, as project.

Cut 28mm

How should I use for 28mm?
Use the blade as in the 1st or 2nd picture? Thanks, Yuri |
Hi Yuri, I think you have the wrong disk for cutting the rail down to 28mm. Your picture looks like a GRINDING DISK. You need a CUTTING DISK. I used a very thin one to cut done my rails. When you grind something, the setup in photo 2 is correct according to me....Correct for grinding the 45 degree bevels on top of the rail.

Thanks Kobus for post,
But, Specification of Norton Brazil - BDA 08: http://www.norton-abrasivos.com.br/D...00000000005035 Disc Cutting 0,8mm Carbide Silicium |
Hi Yuri, the disk looks okay. (use as per second pic). Interesting that you find such a thin disk with a "cup" (hollow) in the center. I only know thin disks that are completely flat.
|
Hi Gerald,
I have the option completely smooth and 0.8 / 1.0 or 1.6 mm (thickness). Which to choose? Kobus you cut the 28 mm with "skate" supported by only 4 screws? Nothing else? He ran the skate supported only by hands? What is the best option for a man cut the 28mm? 1 - Cut as Kobus (sliding skate cut) 2 - Cut Fixed (skate fixed on the table) |
Yuri, I clamped the rail on my table saw top. Then only supported by hands cut a short piece. Then move rail and cut the next piece until finished.
I must say I have never seen thin cutting disks with a CUP in the middle, that is why I thought they were grinding disks. |
Yuri, I like the method of Kobus (and Hennie) . . . . Fix the rail down to a horizontal table, and then use sliding skate. First take light cuts to make a shallow groove and then use more force to go deeper. Move the skate forwards and backwards a lot, so that you never cut hot steel - always cut cold steel.
"I have the option completely smooth and 0.8 / 1.0 or 1.6 mm (thickness). Which to choose?" I do not understand the "completely smooth" part? In general, the thinner 0.8 should be the best, but start with very light cuts to make the first groove. |
I have flat disc or CUP at 0,8 or 1,0 or 1,6mm.
Better flat disk or CUP disk ? |
