Mavic's axle recommendation for the 630 for a single chainring was 110mm (116mm for a double). That puts the chainline at about 42mm. You need Campag (ISO) tapers. Given all that, I think the Primato isn't a bad choice.
With a road rear hub, you have plenty of freedom to respace the axle to get the chainline you want. If you screw a track sprocket onto the hub without respacing it, you'll find the required chainline impractically narrow, so my approach would be to fit the cranks, measure the resulting chainline, then respace the hub to suit.

Yes, in fact I was going to suggest a Campag 111mm unit as an alternative. If you can find one, I'd prefer a mid-nineties Athena, or a Record or Chorus cartridge unit. The latter will be expensive, but they're very good quality. All of those models have adjustable chainline, like the Miche Primato. The modern Veloce doesn't.oaep7":ftpiwr9k said:
As it happens, the Miche Primato, the Veloce, and the mid-nineties Athena are all made by Kinex in Slovakia. The cups and cartridge bodies are all interchangeable: Athena cups on a Primato cartridge, etc.
