Golden Sun GS-201-RB CNC 4th axis
Golden Sun GS-201-RB 8" Rotary Table
Motor mounted behind the table to save Y axis travel and avoid interference with guards on machining centers

1 A combination of high  precision bronze / nickel worm wheel and case hardened steel worm screw ensure long term indexing accuracy.
2 Multi-points pneumatic brake system offers superior clamp torque, insures smooth machining without  deflection under a heavy load.
3 Whatever interfaces as a true 4th for both continuing and positioning machining or a M-code indexer  for positioning machining.
