Designing the X Axis for the CNC Router

This entry is part 4 of 4 in the series Build Your Own CNC Router

 In the last article in this series, I talked briefly about the design of the Y-axis for my CNC Router that I intend to build. In this article, I will conclude the design phase of the machine by discussing the X-axis design concept.

The beauty of this design is in it’s simplicity. The X-axis is made up of a single sheet of medium density fiberboard that is 24″ x 48″ that is beveled to 45 degrees along both 48″ sides. On each of these beveled sides runs a length of 3/4″ x 3/4″ angle aluminum.

The linear bearings of the Y-axis travel along these two pieces of angle aluminum and allows the Y-axis gantry to be moved from one end of the table to the other. A stepper motor will be attached to the front end of the X-axis to which a lead screw will be coupled to create the X-axis motion for the gantry. The lead screw coupling is attached to the lower brace assembly of the Y-axis gantry.

The logic behind the design of this type of machine is that it can be constructed with ordinary power tools and is fairly simple to build. This machine will be fairly quick to construct thereby putting it into operation reasonably quickly. With this machine in operation, I can move on to a much more complicated and permenant design whose parts can be constructed using this machine.

Now that I have the design concept in place, it’s time to start working on the actual drawings for the construction of this machine. I’ll continue this series when I have some drawings to show you. Until then, stay safe, work hard, and as always, thanks for stopping by MVB Crafts.
