Linear positioning tables from Micromech use a steel U-channel body design to give a more rigid structure. They also integrate the bearing and ball screw nut, thereby creating a more compact overall footprint.
Specifically designed to reduce overall machine cost and allow manufacturers to reduce their time to market, the rugged 402XE and 403XE are available in a complete compact package with motor and limit sensors included. For simple customisation, the 402/403XE can be ordered with mounting for other motors to meet customer-specific application requirements.
Due to the utilisation of a steel U-channel body design, a more rigid structure is created when compared to traditional positioning tables. The steel U-channel design also allows for integration of the bearing and ball screw nut within the structure, thereby creating a more compact overall footprint while providing higher load-carrying capacities versus more common bearing/actuator designs.
The tables use a Gothic arch configuration with four points of contact for each ball in the bearing set; this design assures smooth motion while achieving high-precision motion. The 402XE units are supplied as standard in a 50mm wide footprint but, when used with an optional hardcover, the footprint increases slightly to 57mm wide. The 403XE units are either 60mm or 80mm wide without or with the hardcover option. The 402XE comes in four lengths (70, 120, 170 and 220mm) and takes loads up to 90kg; the 403XE has seven lengths from 55 to 605mm and carries loads up to 160kg. Both tables have a repeatability of +/-5microns.
Easily integrated into multi-axis designs and adjustment-free, the tables are said to be a significant cost saver for today's demanding manufacturers. This exciting range extends Micromech's product line to accommodate more application requirements in the medical, hard disk, lab automation, and high-tech markets. They are also a robust option for OEMs and machine builders that currently accept long lead times and poor response times or that currently suffer the frustration of designing, purchasing, inventorying, assembling and testing all the components required to build their own positioning tables.
