The compact R04VI with 4mm maximum machining diameter was developed by Citizen specifically for high-speed, high-precision machining of tiny precision parts.

With a rotary guide bushing unit specifically developed for this unique purpose, the R04VI can now perform metal cutting at speeds up to 20,000 rpm. 

The R04VI also features a subspindle and 2 live tools on the gang tool post to eliminate the need for multiple operations thus significantly increasing your machining efficiency.
