The ZP200 is a platform providing vertical (Z-axis) positioning with a precision straightness +/-15arc/sec throughout the range of motion but capable of continuous duty and a high dynamic performance
This quality designed and constructed lift table from Micromech is a stable support platform, which provides precise vertical translation and positioning, while maintaining XY integrity.
Re-circulating square rail bearings are incorporated into a unique variation of 'wedge' mechanics to enable reliable high dynamic performance without the potential loss of travel encountered with crossed roller bearings.
It can be used with X and Y tables for multi-axis systems and utilised as the system base axis or top axis to fit the motion requirements of the application.
Standard mounting holes and dowel pin holes accommodate repeatable mounting.
There are two basic models, the Precision version that has positional accuracy of 8um and can carry a load of 15kg; the Standard has 20um accuracy and a capacity of 75kg, both have Z-axis travel of 25mm.
Laser tested and certified with calibrated lead value they use precision ground ballscrews with pitches of 5, 10, or 20mm capable of lift velocities of 110, 220 and 440mm/sec respectively.
These rugged yet accurate tables have options of linear encoders with selectable resolutions of 0.1, 0.5, 1.0um, fail-safe brake (which is field installable and mounts directly to the ballscrew drive) and if required Class 10 cleanroom preparation.
There are also selectable motor mounting and couplings for SM16 or Nema 23 servo or stepper motors, and easily adjusted travel 'limit' and 'home' sensors provided in an enclosed sensor pack.
Typical applications for the ZP200 are precise but high throughput situations such as trimming of wafers, measuring or positioning in pharmaceutical, aerospace and telecommunication equipment.
