Aerotech positioning stages achieve high precision

By Aerotech on

Product Details Supplier Info More products

Aerotech has launched a range of industrial-grade positioning stages that is said to offer high levels of positional and geometric precision for harsh production environments.

The ALS2200 range features direct-drive linear servo motors and ultra-smooth cross roller bearings in a hard top/side sealed protection design.

It is aimed at high-precision/high-throughput manufacturing applications such as multi-axis laser micromachining, which typically demands very tight velocity and in-position control combined with smooth motion and micron level straightness and flatness.

Free from recirculating bearing elements and with a high-power, cog-free linear servo motor, drive-induced stage vibration is reduced to minimal levels.

With a nominal stage width of less than 204mm, the range covers a choice of 100mm or 150mm travel with direct load up to 30kg, HALAR calibrated accuracy to +/-0.75 microns, a bi-directional repeatability of +/-0.2 microns and speeds to 500mm/s.

Positioning resolution is up to 3nm with zero backlash.

The small footprint ALS2200 contains the linear servo motor, anti-creep precision bearings and encoder feedback completely within its side sealed protection system.

A full-length metal way cover and tensioned side strap design has been applied.

The vertical side straps prevent debris from accumulating and are under constant tension to maintain a tight seal.

End-mounted motor and feedback connectors facilitate installation and dual X-Y stages can include track type cable trays on the upper axis for a neat cable management system.

The durable aluminium construction includes a scratch-resistant, Teflon-impregnated hard coat finish with the tabletop mounting holes finished with steel inserts to ensure long thread life.

Aerotech’s direct-drive linear servo motors and non-contacting linear encoders are wear free and the MTBF stage life is specified at more than 20,000 hours.

Aerotech can provide a choice of PWM digital amplifiers for best acceleration and speed performance, or low-noise linear stage amplifiers where customers require smoothness and in-position stability.

Both amplifier types combine with a flexible choice of Aerotech motion controls, which suit standalone or multi-axis use with advanced controls, such as the Position Synchronised Output (PSO) command that completely synchronises real-time multi-axis position with laser firing, camera capture, data acquisition or NDT test triggering to produce quality parts or critical accuracy test procedures.
