Star CNC SR-32JIII Type A/B
Category: Star CNC

INFORMATION

The SR-32JIII Type B modular design with slanted guide way increases rigidity, improves accuracy for stable production.

Eight (8) stations back working unit with Y axis provides flexibility in overlapping machining requirements.

Rigid machine construction enables continuous machining with superior accuracy over extended periods of time.

The SR-32JIII is designed to work with or without guide bushing which is another option to further enhance versatility and flexibility while machining.

BENEFITS

  • Standard machining diameter 32mm (34mm optional)
  • Z1 Stroke of 320mm in Swiss mode
  • Higher metal removal rates from increased spindle power
  • Built-in type main and sub-spindle motors for improved indexing accuracy
  • Switchable between guide bush and non-guide bush modes
  • Ergonomic, swing-out operation panel with Fanuc 32i-B control
  • Increased rigidity with dovetail slides on X1 / Y1 / Y2 / Z2
