CNC Machines

Lots of things to consider when you are buying a CNC machine.  Among things you need to consider, in our humble (well, not very, lol) view?

  • Price, price, price.  Under $200 looks good to us.  But, man do some of those upscale machines rock out boat!
  • Power:  Will the machine have a big-enough motor to slam through work?  Remember a couple of points on motor size:  a 5,000 milliwatt motor (divide milliwatts by 1000 to get Watts) is only a 5-watt motor (or laser or….)
  • Speaking of lasing, you want to  mill or  cut burn or engrave?  Because for milling, you want a motor.  For cutting, burning, or engraving you want a laser.
  • Does the machine support interchangeable heads to convert from milling (motor) to engraving (laser)?  Do you care?
  • How big a workspace and how much machine travel can you actually afford?  Big workspace means bigger money….

Here’s out little mill – which handles up to almost 5″ by 7″: SainSmart’s Genmitsu CNC 3018-PRO Router Kit GRBL Control 3 Axis Plastic Acrylic PCB PVC Wood Carving Milling Engraving Machine, XYZ Working Area 300 x 180 x 45mm. $249.

Since we like the whole “Keep it in America” idea, though, for bigger machines we lust after one of those Bob’sCNC rigs.  Like this bad boy: “/div> <
