New Precision, Multi-axis Air Bearing Gantry System from Steinmeyer

BURLINGTON, MA — Steinmeyer, Inc. announced a new precision, multi- axis air bearing gantry system. This motion system consists of an XY stage utilizing air bearings plus a conventional ball screw driven Z table. It is ideal wherever there is a need for ultra high precision and outstanding dynamic performance.

Typical uses include:

- laser machining
- inspection systems
- pick and place devices
- dispensing systems, and
- gene chip production equipment.

These stages (which may be completely customized) achieve the following standard XY specifications: travel is 600 mm X 600 mm, positional accuracy is 10 microns, positioning repeatability is +/- 1 micron, straightness and flatness is 1 micron. Both X and Y stages are driven by ironless, electrodynamic linear motors with maximum acceleration of 10 m/s² and velocity of 1000 mm/s. Position feedback is accomplished via an incremental linear encoder with a resolution of 50 nm. Typical Z stage performance includes: 25 to 200 mm travel; positional accuracy of 10 microns; and repeatability of +/- 1 micron. A separate motion control option is available based on customer specifictions.

Multi-axis Modular Assembly from Steinmeyer

BURLINGTON, MA — Steinmeyer, Inc. announced a new multi-axis modular assembly designed specifically for 3D target positioning and alignment. Typical applications include R&D and scientific uses such as synchrotrons. For example, the new system is ideal for beam positioning and sample manipulation.

The assembly utilizes the compact Steinmeyer type MT130 linear stage together with a type DT110 rotary stage to yield two to four axes of motion – XY, X-rotary, XYZ, XY-rotary, or XYZ-rotary. Each of the MT130 stages offers 50 mm stroke with standard flatness/straightness/repeatibility of +/- 1 micron. Maximum speed is 50 mm/sec. The linear stage is driven by a miniature Steinmeyer precision ball screw and includes crossed roller bearings, limit switches, dc servomotor and rotary encoder.

The DT110 rotary stage has a +/- 1 micron flatness of rotation and repeatability of +/- 0.002 degrees. Maximum speed is 200 degrees per second. Precision brackets are used, where necessary, to easily connect the various stages to achieve the final multi-axis configuration. A compact 2 to 4-axis DC-Controller is available with “plug- and play” characteristics, including LabVIEW® compatibility. Standard options include joystick control and direct reading scales for higher accuracy.
