Advice on type of CNC Machine to buy/build

[JAZZCNC]

Hi JazzCNC,

Thanks for this. What is the problem with DC motors for the spindle? I'm going to buy one of the 3040's to learn on, then look to build a serious one for milling con rods, etc. What type/size/power cnc do you use? Can you recommend a kit/spec that will handle aluminum blocks?

Cheers

Gary

The use Carbon brushes and burnout in no time. Complete rubbish best avoided.!!

For milling aluminium you'll want a spindle that can run between 7000rpm and approx 18000 dependent on tool size. Water cooled 2.2Kw works fine for cutting aluminium and suits routing softer materials as well with it's 6000 to 24000rpm range.

That is a toy, not a machine. Its a recipe for frustration. Plus buying it from people who sell tattoos... I wish i could forbid somehow that "machines" from selling

Hi silyavski and JazzCNC,

I am definately looking at better quality machines now and increased my budget considerably.

Thanks
