RE: [CAD_CAM_EDM_DRO] Re: small spindle ?

Honestly, 0.0025" or an inch is a HUGE amount of run out. Even the 'premium'
spindle is only quoted as 0.0015" which is also a HUGE amount of run out.
Those types of motors are likely not designed to take and side load imposed
by cutting so the bearings will likely not last very long.



Just my 2 cents
