ABTech inc provides this turn-key motion system solution for resolver and encoder testing. Using our precision ball table design incorporating a brushless DC motor drive and high accuracy angular encoder we developed this test station capable of holding rotational position to less than 1.25 arcsec. The system includes the rotary table, motion controller, PC and application software front end.

Features:

  • Ball table with direct drive DC motor
  • 36,000 line count encoder
  • Delta Tau motion controller
  • Turn-key system includes PC
  • LabView application software front end
  • Radial and axial accuracy: 50 μ" or less
  • Radial position accuracy: 1.25 arcsec
  • Position resolution: 0.0087 arcsec

ABTech's high precision mechanical rotary index tables combined with Heidenhain's RON 200 series encoders and ND 200 series single axis displays make an ideal set up for high precision light-duty machining or metrology inspection.

The rotary tables feature sealed 4-point angular contact bearings, providing high stiffness and radial error motions of 50 µ"(1.25 µm) or better.

The drive is a bronze worm gear (50:1) manually driven by an ergonomic hand wheel. The modular design approach accomodates motor driven versions, including amplifier/controller options and complete turn-key systems.

The single axis display provides easy operation and easy to read digital display. An RS-232-C interface is available as well as switching inputs and outputs for simple automation environments.

Features:

  • 4-Point preloaded angular contact bearings
  • Sealed bearings for light-duty machining
  • High stiffness & load capacity
  • Radial error motion: 0.00005" (1.25 µm)
  • Worktable face runout: 0.0002" (50 µm) or better
  • Worktable diameter: 8.00" (200mm) standard
  • 50:1 worm drive
  • Precision rotary encoder (±7 arc sec accuracy)
  • Stepper motor drives available
  • Heidenhain ND 281 single axis display
  • Manual position lock
