Description
ㆍThe spindles are designed and manufactured by CHIFA's own R & D. The spindle has unique precision, lfespan and high rigidity cutting feature.
ㆍHigh-low and continuous variable speed gear driven design. Gear manufoctured by alloy steel is hardened and grounded. It is suitable for low-speed high-torsional force heavy cutting.
ㆍUsing floating tool clamping system to ensure the precision and extend lifespan of bearing.Head of gear used forced circulating cooling to control thermal change,so that can ensure long-tern cutting precision.
ㆍSpindle used P4 class precision angular contact ball bearing and long span support design, that can sustain radial and axial thrust for long time.It is suitable for heavy cutting.
ㆍSpindle nose used labyrinth ring with air curtain of spindle, to avoid permeating chips and oi gas and ensure the precision and extend lifespan of bearing.
