Cnc spindle 2.2kw- what material can I work on?

>>1101210

Just about anything you'd use a 3hp router for...

>>1101221
Yeah, I mean if someone hast this spindle and can say what they're milling. I'm an electrician not Mechanic so I got no experience. I have a calculated force of 3760N per axis so maybe 3000N. The spindle will be water-cooled with 4500l/h so I can go down with the rpm. I still did not buy everything as I'm still trying to get the big picture. Pic related, cnc 6040, should be quite the good and sturdy frame for the price.

And I have a good inverter from SEW with boost function for torque at lower rpm.

You can work any material you want with it. It's all about feeds and speeds. I use a 1.5 hp 90 vdc motor to mill everything from plastic to mild steel. Sure I can't run at 80 ipm or have as deep of pass but it gets the job done.

Entirely depends on the rigidity of the machine its in

That looks like the spindle of a CNC router. You can use it to make sawdust.

Can you visibly twist the whole contraption by hand? If so, you will still be able to cut aluminium, but with painfully shallow passes, an awful finish due to chatter and poor positioning due to the tool head wandering.

wax, plastic, wood, soapstone, pcb should be ok.
brass or alu maybe.
forget steel.

So it's the cnc 6040 from 2nd picture, you think I should rather save those 60 bucks and get the 1 5kw spindle? I'm interested in milling Aluminium.

Well spotted, I already said it's a cnc spindle. How important is rigidity when I do 2.5d work?

the frame doesn't look like it can push hard enough to stall a 1.5kW motor.

>How important is rigidity
it's the single most important thing.
the machine has to soak up the kilowatts of forces applied at the tool tip.
if it flexes instead of cutting there is no precision; you aren't engineering, you're metal graffiti.

this

there are tons of china made 3-axcis manual mills wich can be converted to CNC with a kit BUT even though they have CAST IRON frame, they are still rarely rigid enough to get good surface results

speaking from experience, bought this HBM a year ago, its somewhat good but it still cannot handle really deep cuts on steel and such,

so anything with aluminium frame, i would not even try to use it on any metal, other than perhaps led, that could be soft enough

Is that the same as the G0704 or the PM25?

Ive been seriously thinking about picking one up

>>1101751
Looked at a Optimum BF20/ BF20L but the 105kg weight and the small y axis reach of 175mm was bad. I will never use the huge 290mm z axis range.

>. I will never use the huge 290mm z axis range.

Things get a whole lot shorter when you have a vise and tooling, especially standard sized drills and reamers in a chuck.

>>1101751
How does the vertical axis work, with a leadscrew?

>>1101751
how deep of a cut we talking on your mill? 1/8 or 1/4?

>>1102272
Vise, chuck, and tool is going to leave like 25mm to work with

>>1101753
yes, its basically the same, with different paint and logo, they are all china made and CAN CAUSE a lot of headache, but I've so far been satisfied with mine

>>1102216
mine is equivalent to optimum bf 25, it has morse cone mk3 instead of 2 wich is a big fucking difference in rigidity, and this one has about 350 mm z- range from the bed to the spindle face

>>1102671
yes, there is a crabk operated trapeze lead screw for the z- axis and a fine feed screw on the spindle with digital readout

>>1104234
I can take about 6 - 8 mm deep cut in brass with a 10 mm tungsten bit with no problem and about 3 - 4 mm single pass cut in stainless steel without any problems

>>1101373

Rubbish, you can do brass and aluminium on a 400W spindle if your feeds etc are slow enough.

>>1106111
this, a dremel is about 150 w and even that can eat aluminium and brass with a proper sized milling tip with proper feed rate

The problem here is not power, but stiffness of the setup.
