RT Series Rotary Index Tables
Standard Features
  • Heavy, Preloaded Bearings - Heavy, preloaded bearings insure spindle rigidity, stiffness, and accuracy.
  • 360,000 Position Indexing - Positioning at distinct angles as little as
    1/1000th of a degree apart permits drilling, tapping, milling and boring of part features. In addition, rotary feed milling allows cutting,
    o-ring grooves, etc.
  • Accu-Smart Control - The user-friendly Accu-Smart Control provides flexible and powerful programming.
  • RS-232 Command Capability - Interfacing to the machine control via RS-232 keeps all rotary commands inside the CNC part program; no
    programming of a separate device is required.
Construction
  • Heavy preloaded anti-friction bearing mounted spindle eliminates end-play, provides long, accurate, rigid life.
  • Oversized, power operated, high-torque brake provides rigidity to withstand heavy cuts or offset loads.
  • 360,000 position indexing - certified 4 second repeatability.
  • Removable faceplate. A-6 Spindle nose accomodates direct-chuck-mounting without adaptor plates.
  • 2-Year warranty with installation by SMW.
  • IP-67 Submersible-rated, molded cables with steel mesh abrasion protection.
  • LipSeals and Poron gaskets thoughout.
  • Brushless Servo Motors.
