I have started to make a cnc mill I'm new to all this but I'm having a go.
I made a wind turbine but could not make the blades all that well my hand .
so I thou rt I would make a cnc mill to make the blades.
I would like the working bed to be 1000MM by 500MM .
one day i will make a web page for the cnc mill
here some off the parts the bed is 30MM facing ply it is not supported in the middle i will have to see if it will bend (i think it will )

here is a close up of the side i have 30mm ply and a 20mm box steel i Hope this will take all the wight of the y

Hi - neat project. Not sure if the ply will bend or not, but that is reasonably thick. Perhaps the rails will bend first before the bed.

i have had to have some parts made i could not make them bye hand they cost £60 it-is a shame i could have made them with the mill when its finished umm

I have got the z axis all done the plate witch holds the motor on is a bit thin I will change this for something stronger

Hi - neat project. Not sure if the ply will bend or not, but that is reasonably thick. Perhaps the rails will bend first before the bed.

I have found that the ply did bend so I will add a 5mm sheet of steel to the top and change the way my X axis will work I was going to drive it with a led screw I will support the bed in the middle and belt drive the axis which will also speed it up to

I have put the 5mm steel sheet on the bed and it is all nice and strat now

[catsam]

I have change the plate which holds the motor on the Z axis and also put a bearing to take out the play in the belt

[catsam]

here is the mill with some new rails which I got from ebay and the 5mm steel sheet for the bed of the mill

[catsam]

my mill is geting there I have put some cool cable chain on it and gave it some paint

That is great progress. Just curious - how thick of Al plate did it take to make the belt drive nice and stiff ?
