New Build, Aluminium Frame Router/Mill

[Davek0974]

Yes, thats the plan, it protrudes enough to get me over the screw so i can fit a drop bracket for the nut. The cutout clears the Z axis motor body.

The Z front plate and the very front plate where the tool mounts are 20mm thick and needed 7.5mm taken out of each to align the rails and screw. I don't feel that will make any difference at all to strength - the tool mount plate is also reinforced by having the linear rails bolted to the back of it. The rear Z plate is has the Z axis linear carriages aligned directly with the support plates (shown in the pic) for the X axis linear carriages - the forces are transferred directly from Z to X.

Having built two plasma tables out 3mm steel which were still very sturdy, this thing is being built like a mini battleship!

Thanks, I also think the forces are pretty much directly transferred from Z-carriages to X-carriages. One important task the z-plate also does is keeping the rotational forces at bay, and I agree, 7,5mm less wont make a speck of difference.

I will look over my own drawing and see if I cant do the same.

I know that one, my Z front plate is 40mm thick...think I only took a similar amount out of that, overkill??!!

Better over than under ;)

Day off today so hit the project...

X / Z axis finshed...


Rear face of the tool mount plate with the linear rails...


Front of the Z axis with some linear rail carriages in place...


Back of the Z axis with the X axis carriages in place...


Rear frame support plate fitted to the main beams...


Next up is the front frame plate and mount for the Y axis motor. :)

Bit more today...

The bare frame - extremely rigid, surprised me!


Inside of the front plate (maybe the back, not sure yet) idler bearings to shift the belt path...


The Y axis screws temporarily fitted...


The gantry being built up...


The Z axis in place...


Z axis lifter screw and motor fitted...


So far, my CAD efforts have been 100% perfect, every single part drawn has fitted just where it should be Torsionally, the gantry is very stiff - pushing on one side brings an immediate response from the other which is good, the Z axis looks like it will be just as tight.

Now i need to fabricate an idea for a method of joining the Y axis nuts to the gantry cross-beam.

Certainly is Jazz, this thing is probably more rigid then 'Mr Flexy' the Bridgeport ;)
