Aerotech (www.aerotech.com) has released a broad based version of its ABL1500 air-bearing linear translation stage, specifically designed as a base for X-Y systems or for high precision positioning of offset and heavy loads where maximum support is vital.
Offered in four travel options starting from 200mm to 500mm, the ABL1500WB features a nominal width of 400mm. Possessing a powerful dual linear motor drive and a selection of high accuracy or standard precision linear encoders, the stage can withstand a direct load of 60kg with submicron accuracy and resolution, and delivers up to 2m/sec and 2g of speed/acceleration.
ABL15000’s all aluminum stage benefits from an active air preload system for certified flatness/straightness of less than +/- 2.0 microns for the 500 mm travel version. It is also targeted at high test applications and throughput manufacturing in nanotechnology or semiconductor production that demands a no-compromise performance for step and repeat or scanning positioning.
Aerotech’s exceptionally high stage stiffness with advanced offset load handling characteristic is attributed to the stage’s active air bearing design, which sustains equal pressure on both horizontal and vertical bearing surfaces and distributes the load of the stage across the maximum area. Its brushless linear servo motors, air bearings and non contacting encoders all contribute to the stage’s negligible friction. It also requires minimal maintenance requirements.
The stage can be supplied individually or with other positioning mechanics as a multi-axis engineered system. The systems enable machine builders and OEMs to realize their automation needs. These can also include cabinet frames, special fixtures, granite base and various advanced machine and motion controls that combine to enhance production throughput, development timescales, and customer product’s final quality.
