What is the Total Cost of Conversion (Excluding the Mill)

[dazp1976]

If you want a challenge you may be better off DIY building a strong Fixed gantry Router/Mill that will do everything you need and then some with the correct spindle fitted. It will certainly be more versatile and useful than a converted Minimill and won't cost much more. Here's one I built a few years ago (yellow one) with a 500 x 500 cut area and also one we built recently that is fully covered designed exclusively for cutting Aluminium moulds with a cut area of 600 x 400 which is more or equal to many industrial CNC machines but fits in a 1mtr/2 space.!

ATC BT30 Cartridge and 5000rpm servo drive belted to 7500rpm at the nose, too heavy???.

Or is there a 6k-8krpm ATC BT30 motor option out there?.

Yep Cartridge and motor setup would be too heavy but we can have custom-built water-cooled ATC electro spindles with BT, HSK, or ISO tapers in usual sizes 20,30,40,63,100, etc with power ratings from 1.8Kw up to 40Kw with speeds and torque ratings up to 60K and 120Nm.!

So yes having an ATC BT30 with 6k-8k rpm is no problem, either flanged (cartridge) or straight body spindle type. Can even have with encoder for ridged taping or orientation and thru coolant.
