Cutting parts, that's what its all about

CNC @ HOME!

10 Years anniversary!

Let's celebrate that with a new design and make some chips

Currently preparing for production & presentation.

A compact CNC machine with a large workspace.

Here a preview of what to come next.

Prototype XXL version extending X to 1200 workrange

Now under my X-mas tree!!!!!

Merry Christmas and a good & healthy 2012!

Specially for educational and public purpose

a suitable enclosure is under development.

Here shown the kitset from the first serie produced batch,

also the trial fit of the parts.

Exiting moment and yes it does fit great!

Yey!

Here the structural mechanics assembled into its final apearance.

Testing carving some Oak.

I am getting used to the CNC-USB software now more and more.

Toolblock to testfit the Led-Arc, a pcb combining nine LED's around the cutter.

A simple MDF Jig to place the PVC- (ALU) blank in for

precise positioning and cutting of the needed shapes.

After finishing the cuts....

LED THERE BE LIGHT!

Of course some vinylcutting for stickers I need....

For a project about 15 spacers quickly where needed as shown below.

How to achieve this the easiest way?

Take a suitable blank, cut the material as from the design and slice it

by sawing it up in 15mm strips.

fixation & positioning by cutting a 7mm deep pocket in 20mm scrap MDF.

It fits tightly and no need for fasterners

Using a 8mm single cutting cutter, at about 15000 RPM at 1000mm per minut.

2011-CL-Alutrial 2

The aluminium chips do not cause any problem to the railsystem as these just get buldozered away....(Although not designed for this purpose, trials showed it even can be used limited for cutting brass and aluminium cutting)

USB-controller powered with excellent, easy to use software from Planet-CNC:
