CNC Shark

At the Melbourne Woodworking Show, Carbatec were displaying a soon-to-be-available machine – the CNC Shark.

It is a computer controlled routing system, capable of controlling a router in 3 dimensions (a 4th is possible as an upgrade, which you’d use for something like controlling a rotating cylinder for carving into a turned object – imagine engraving into pens)

It is connected to a PC via USB and comes with the required software to run the machine. You create the original designs using programs such as Corel Draw, or Adobe Illustrator.

The router mounted in the machine is only there for show – it is not pneumatic, or requiring someone to blow into the tube (not sure if I managed to convince someone at the show of that or not!), and you can use all sorts of router bits for different effects.

It is constructed of steel, aluminium and high-density polyethylene, has 3 stepper motors to precisely control the bit’s location.  It can move a maximum of 24″ longitudinally, 13″ across, and 4.25″ vertically, with a resolution of 1/1000th”

As you can see from the demo video I made at the show (handheld sorry), it takes a number of passes as programmed to remove all the material required.  For part of the video, I used sticky tape to secure the camera to the machine itself (which is why it looks like the material is moving, and not the cutter). And it is a demo of the program running – you won’t see the cutter removing any material (think some people were confused by that at the show).

It will cost just shy of $5000, so won’t be in every workshop, but I bet there will be some enterprising people who will jump at it, and start creating components for model aircraft, makers marks, wooden business cards, signs (obviously) and, well, wherever your imagination can take you. If your computer could “print” in 3 dimensions into wood, this would be the printer!

If you are particularly interested in the machine, contact Tony Forbes at Carbatec, Brisbane 07 3397 2577, or check out the Carbatec stand at the various woodworking shows. (Oh, and do mention you saw it on Stu’s Shed!)
