Re: [CAD_CAM_EDM_DRO] Re: Laser specs ?

yep, commonly run at speeds between 130,000 rpm and 160,000 rpm, air bearing
spindles with high frequency VFD type invertors.
sad to think these are made in china on american machinery only 10 years
old. i have 4 now antique driller spindles ran on cearmic bearings at 70,000
rpm. tossed out 5 years ago as too slow for production. enjoy the new year!
