Hey Stormy 320,
The machine I was referring to is my cnc router.
It’s probably the best pieces of equipment I’ve ever owned and probably the most expensive.
We use it mainly for our architectural models - for cutting out the multiple windows in buildings.
It basically cuts what you draw in a Cad programme.
We generally use cutters between 0.5mm and 6mm diameter, but when I cut the discs I used a 19mm diameter cutter.
To hold the material in place whilst cutting, the machine has a built in vacuum bed which sucks the material down tight and doesn’t allow it to move.
The machine will cut plastics, Mdf / timber, resin, foam and most non ferrous metals. It won’t cut steel.
When cutting out very small and delicate parts we also tend to glue the material down using a non permanent aerosol adhesive called Spray Mount.
If we don’t do this the components either get sucked up the swarf extractor or shoot of the machine never to be seen again!!
It’s a brilliant piece of kit and I don’t know how we’d manage without it!
