Help on building an enclosure

[thomashomer1986]

Thank you everyone for your replies!

Right to start with then I am going to draw it out on inventor to get a better idea of the layout

Main points to consider then:

1. Steel or aluminium cover. (whatever my workplace has available)
2. Hinged lid, with an earth point to connect it to the main case
3. Raised steel platform for mounting the components onto. This is then earthed to casing.
4. Star grounded earth setup, maybe a bus bar to make earthing easier, which is then connecting to casing earth point
5. Additional space for upgrading.
6. Cooling fan and filter setup. 2 intakes/1 exit
7. Suitable mounting holes for attaching to wall etc.

Anything else?

One other question, I'm yet to get my WC spindle. Does VFD need to be mounted inside the enclosure as well then?

Yes, read the manual regarding free space for cooling. For example mine needs no free space at the sides but needs 75mm clear top and bottom for cooling.

Also at the bottom you can see the terminal rail, this doubles up as my earth bus bar because the earth terminals clamp onto the DIN rail which is earthed by the incoming supply cable.

VFD Doesn't have to be inside the enclosure but like Eddy says it does need cooling space if you do.

To be honest I don't Like VFD inside same Enclosure because it introduces high potential for noise interference on other components.
Also I like to see the VFD display and have it Set to Amp's this way you can tell when cutter is getting worn has the Amp's rise has it wears.
