Case Study: Diagnostic system with 3-axis linear positioner and super-high-precision rotary indexer

Pain Point

A global manufacturer of diagnostic equipment required a custom, fully tested and assembled XYZ platform with rotational positioning to allow continuous reagent processing. Extended lifetime to ensure uninterrupted operations was essential, as was greater rigidity and smoothness over lead screw-based actuators. Specified travel requirements, load conditions and envelope dimensions for their diagnostic equipment had to be met.

Multi-axis linear positioner with rotational indexer

NSK Direct Drive Megatorque Motor with multi-axis Moncarriers.

Solution

  • Robust, NSK-designed, pre-assembled diagnostic system, featuring (3) miniature Monocarriers for X-Y-Z positioning, along with sensor, sensor rail, combining brackets, motor brackets and stepper motors
  • Super high resolution and torque, NSK Megatorque motor to rotate the three axis stage in small increments and discrete locations along the platform for precise positioning of the dispensing nozzle
  • Equipped with K1 lubrication units for maintenance-free operation as long as 5 years or 10,000 km travel
  • Execution of design validation, ensuring proper rigidity and repeatability of assembled system for the application
  • Quality assurance testing of each assembled system prior to shipping
  • Use domestically-made precision products
