Q: What type of metal is this enclosure? Anodized aluminum? Is it easily machinable?

It is made of steel with what appears to be powder coated. I have used several of these to build test equipment and find them easy to machine to install meters, etc. Make sure you get one big enough. The white plastic frame extends into the enclosure and decreases the mounting space available on the bottom. For instance: the 7.09" x 5.12" x 4.33" Enclosure has 6.75" by 3.5" of surface to mount parts on. I would expect that about all of these enclosures will lose about 3/4" of usable floor space.

Q: How is this dustproof?

No, this metal enclosure has vent.

Q: What is the size of the front panels for box 7.87" x 6.50" x 3.54 ?

the size of the front panels for box 7.87" x 6.50" x 3.54 is 185 mm x 78 mm/7.22" x 3.04".

Q: Do you make this without vent holes?? This would be perfect for many applications if it didn't have them.

the enclosure box without vent holes is need to be customized, we cannot make it temporarily. In the future, we may put this type of goods on the shelves.
