CNC is an acronym for “Computer Numerical Control” which is the act of controlling a machine with a computer.  Usually, this refers to various types of fabrication equipment.  As you might expect, many such systems are designed using stepper motors. TMG’s CNC retrofit kits allow computer control over:  mills, mill/drills, lathes, light machines, routers, glue dispensers, gasket cutters, sign makers, sharpeners, etc. The kits come with 2, 3 or 4 axis of control (e.g. x, y, z axis and table tilt).  The kits come with CNC software (Windows based) that includes milling, drilling and letter engraving routines. The kits work with Mach 3 software (a popular CNC software for mills and lathes).  You can get it here. You’ll have to fabricate motor mounts and you should have a way to mount limit switches. The video you see here is the CNC that we use in the shop.  It predates everyone here at The Motion Group and our best guess is that it was set up about 15 years ago.  It’s still in regular use today. We use a three-axis configuration (X, Y and Z).

You can see the motor mount and belt assembly clearly on the X axis assembly on the right of the image (above).  You can also see a front view of the setup on the Z axis on the bottom front of the equipment. (Click here to see our CNC kits.)
