I need to cut some backed vinyl sheet to make some bespoke letters and numbers for the number-plate on an old motorcycle. I have a small CNC mill which I drive by making .dxf files from which I make GCODE that I send to Mach3, which then drives the mill.

I’m aware that one can buy small vinyl cutter knives cheaply on eBay and that these operate in swivelling heads which can be fitted to a CNC mill or router. There seem to be quite a variety of heads available, at a very wide range of prices. One of the cheaper ones seems to be:

I would very much welcome advice from people who have cut vinyl sheet this way on selecting a swivelling head that works ok.

Practical advice on setting up the mill to cut vinyl, e.g. downward force needed and how to achieve it, type of backing and how to mount the vinyl sheet, any things to watch out for, would also be very welcome.

Thanks for all help,

Jon

Thanks for replies so far.

I'm really looking for advice from people who have cut vinyl sheet this way regarding selecting a swivelling head that works ok. I'm also looking for practical advice on setting up the mill to cut vinyl, e.g. downward force needed and how to achieve it, type of backing and how to mount the vinyl sheet, any things to watch out for, would also be very welcome. If I can get a working system then I will have other uses for it, e.g. cutting gaskets or lettering for such as tank badges.

Kind regards,
