Flexdrive- 4 Features & Benefits

The flexdrive-4 positioning tables series is an expansion of the product line to a small compact size and the modular design makes it an ideally suited translation module for a larger number of applications requiring precision, reliability and ease of integration. Engineers, system integrators and designer prefer the flexdrive-4 for their superb performance, flexibility to match to the application and assured longevity.

The flexdrive-4 positioning tables series is a very compact precision stage based on a monolithic high strength aluminum alloy with a 48x100mm envelope and travel range from 50-450mm.  The payload capability is rated at 50Kg(100lbs) with a technical limit at 280Kg(600Lbs).  The superb positioning performance is supported by square rails with recirculating low noise  linear ball bearings and a precision ground ballscrew drive with 5 year lubrication intervals.

Applications

The flexdrive®-series positioning tables have been a very successful translator product for two decades and are recognized for their sustained positioning performance and longevity in many applications like laser machining systems, bio-medical, metrology, instrumentation and automation.  The outstanding selection criteria are the reason why professionals prefer the clean, modern international metric design of the flexdrive series stages by NUTEC.  The designers preference for these modular concept positioners can be attributed to configurability for specific application requirements, the excellent specifications and the sustained performance coupled with longevity.

Drive Options

The flexdrive®-series positioning tables are available in three different screw drive options.  Select our PN drive for lowest cost execution.  Select the Ballscrew drive for higher loads and higher duty cycles.  Select SR drive for applications demanding high stability.

Sensor Options

Standard
For limit of travel and home position there are 3 LED sensors available, mounted internal to the stage.  The electrical connection is at the motor end bulkhead with a DB connector.
        

Optional External
For applications where the travel limits needs to be adjusted in order to protect a payload device, a user adjustable external sensor option is available.  The three LED sensors are mounted on an external rail with a bulkhead DB connection
