My first cnc router of wood (MDF)

I am (part of the time) an NVH specialist for a car manufacturer.
When we want to put a part of the system in a box so that we can measure the noise level of another part, we build the box of plywood and line it with a special self-adhesive foam / lead / foam sandwich.

The foam / lead / foam material is the most effective thing for this job. You probably also should mount the whole router on a layer of foam to eliminate structure-borne noise through the table to the floor. Also make sure that your box is not touching the wall.

One of our vehicles had a very noticable noise in the driver cabin. It was eventually fixed by fitting a longer and softer engine earth strap. So don't assume that no noise can come down the wires.

mount the router on some rubber feet , and the same with the case , and as andy says keep the box away from touching the walls . will help a great deal in isolation of noise .

sorry for my late answer, I was busy Thank you all for your help

@globaldynamix: nice video, looks very good and professional

@Andy: I made the box of particle board (hope is correct, in german "Spanplatte" or "Pressspanplatte"). Tomorrow will arrive my ordered damping foam.

@cncbasher: I have 3 mm rubber plates, I'll put them under the box and the router.

The box is almost ready, foam will arrive tomorrow and my dust extraction too...

Is the sort of stuff you might need.

my first cut is done - Dust collection / shoe :woohoo: :woohoo: :woohoo:





nice cut, milling cutter was cold after milling and the noise is acceptable. The vacuum cleaner is louder then the cnc router



I know, it's not perfect, but it's my first cnc router I was building. It's only a prototype to test the hardware and so on, the next parts of wood are at home. I had problems to put the holes for screws and stepper motors, as sample, on the right place. I used only a simple drilling machine, so now I think the parts will be a lot better and then I'll build the cnc router again.

Looks good!
