Victor's own Spindle

All spindles are manufactured in-house by Victor Taichung, and each carries its own unique I.D. code to
facilitate future servicing requirements.
Oil/air lubricated design to spread the oil into the spindle bearings by air ensures sufficient lubrication and
longer service life than grease lubricated design.
o
Unique spindle bearing layout 4+1 with 25 contact angle for 12000 rpm spindle of Vcenter-AX350 (and 15˚
contact angle for 15000 rpm spindle of Vcenter-AX800) ensures high cutting rigidity.
o
Optional 2+2 bearing layout with 15 contact Extremely rigid facilitates continuous high speed machining.

Oil Cooler for Spindle
While the spindle structure is built for maximal rigidity, the spindle
oil cooler is installed to circulate coolants around cooling jacket of
built-in spindle to ensure longer service life for spindle bearings.
This oil cooler is also included for DCS (Directly Coupled Spindle)
to prolong service life of spindle bearings.
