Hey all, Im looking at buying a automatic tool changer spindle from here:
China JGL-80 1.5kw 2.2kw 2.5kw 24000rpm 40000rpm ISO20 ATC Cnc Spindle Motor Suppliers, Manufacturers and Factory - Customized Products - Jingjiangcity Jianken High-Speed Electricmotor Co.,Ltd
The is a 1.5Kw, 2.2kw and 2.5Kw version with max rpm 24k, 30k and 40k rpm respectively.
Ive contacted them and asked for a RPM / Torque curve but so far they have not sent me one... im just concerned the 2.5Kw version will only make usable power at 30,000 to 40,000 rpm? and since I currently operate mainly around 20,000 rpm would I be better off with the 1.5 or 2.2kw version?
OR would it be a linear curve and the 2.5kw version would make 1.5kw @ 24k rpm, 2.2kw @ 20krpm and 2.4kw @ 40krpm? and they are all basically the same spindle just possibly the 2.5kw version has upgraded internals to allow it to run at higher hz / rpm?
