Thread: New CNC Mill on the horizon
My stuff arrived today has well, wonder if they came on same shipment.? Don't know if dare say this but my stuff is ok but I did have other stuff which supported the screws plus they where only 1300mm long.
Depending how bent then like Jon says V bollock and plenty of force, I've straightened screws before but it's slow process and easy to over do and bend more.
If not too bad then I'd fit on machine and see how they perform, sometimes they can be ok when running and not affect machine too much.?? . . .they can also shake the bastard to bits but worth a try.!!
My ball screws from Chai were wrapped in plastic, encased in foam and wrapped in a cardboard square tube/box which was liberally wrapped in yellow tape. Not checked mine yet to see if they're straight....might be doing that sooner rather than later now!!Neil...
A fair bit of work this weekend and the basic frame of the gantry is done. Lots of measuring 4 times and drilling once but its all worked out really well everything is nice and square and meets up well could not be more pleased.
I have to say a big thank you to Jonathan for organising for the gantry sides to be cut so quickly, collected this morning and on the gantry by this eve.
Now its started I dont think I will be out of the workshop for a while, good job the missus has gone to South Africa for two weeks!
Another weekend of work and the gantry is really coming together now.
Got the y axis ball screw fitted, motor mount machined and fitted inside the gantry, x axis bearing plates milled and drilled and test fit on the rails on some trestles.
Looks like I need to get some more material together for the z axis!
btw, the x rails are screwed onto the trestles I was a bit concerned one side might just fall off!
Did you really need to over build the base frame that much and how do you plan to attach the ballscrews and motors to the trestles.?. . . . Lol
Looking Good Francis sorry I was too busy to help with machining but looks like it's coming along nicely, keep up the good work. .
probably not but I can always have the parts out and pocket sections of the parts which dont need quite as much strength in the future.
Thanks for all the init and I know your busy so its not a problem :) hopefully it keeps going as smoothly.
That is one meaty and sturdy gantry and quite a good design.Spelling mistakes are not intentional, I only seem to see them some time after I've posted
i cannot take credit for the design - well other than my version of...... it was a design jazz put up ages ago that I took the cues from
