Aerotech ASR1100 Mechanical-Bearing Direct-Drive Rotary Collet Stage

Extreme throughput. Unrivaled reproducibility. Aerotech’s ASR1100 delivers

industry-leading precision and dynamic performance in cylindrical tube-

processing applications.

Aerotech’s ASR1100 delivers industry-leading precision and dynamic

performance in cylindrical tube-processing applications. Optimized for

extremely high speeds and accelerations with outstanding cutting precision,

ASR1100 improves part reproducibility and reduces unit costs for cylindrical

medical components like stents, hypotubes and guidewires.

Configure the stage with a Schaublin W12 dead-length collet chuck for

high-precision tube advance-and-regrip processes, or use an ER16 collet

for more variable workpiece diameter range. An optional wet-cut rotary

union supports active fluid cooling, while the compact design maximizes

multi-axis dynamic performance and simplifies system integration.

Pneumatic Collet Chuck

The ASR1100 greatly simplifies workholding with an integral pneumatic

collet chuck, configurable to order based on your tube processing application

requirements. Options include:

ER16 Collet Chuck: Ideal for general high-precision manufacturing, ER16

collets accommodate a wide range of tube sizes ranging from 0.5–10.0 mm

outer diameter. Each ER16 collet size supports up to a 1 mm tube diameter

range (e.g. 2.5–3.5 mm, or 5.0–6.0 mm). ER16 collet chucks are normally-

closed, requiring air pressure to open. Aerotech recommends Rego-Fix ER

collets manufactured to ISO 15488 / DIN 6499 specifications.

W12 Collet Chuck: Ideal for processing longer tubes ranging from 0.3–8.0

mm outer diameter, especially when the tube “feed-and-advance” accuracy

is paramount (such as when processing longer tubes requiring multiple “grip

-advance-regrip” operations). Because this is a dead-length collet, axial error

motion during tube advance is negligible. This minimizes spot-placement and

stitching errors. W12 collet chucks are normally-open, requiring air pressure

to close.

Optional Wet-Cutting Capabilities

Does your manufacturing process involve liquid coolant or another cutting

fluid? No problem. ASR1100 is configurable for wet-cutting, thanks to an

optional fluid rotary union. The -WCUT option provides a fluid inlet and

eliminates the need to manage hose rotation and wind-up. Cutting fluid can

then safely flow through the rotary axis’s hollow shaft and the workpiece.

Consider the dry-cut option if cutting fluid is not required or if you prefer to

integrate your own external wet-cutting features.

Options Include Vacuum Preparation for 10-6 torr

A number of options increase the flexibility of the VTS300 series stages for

a wide range of applications. Vacuum preparation for operation in vacuum

chambers to 10-6 torr is available. The stage also has movable limit switches

so that customers can adjust the travel range.

ANT95LZS stages represent the ultimate in vertical motion performance

with an ultra-low profile. Featuring dual side-mounted pneumatic

counterbalances with extremely low frictional characteristics, they are

best-in-class in combining resolution, accuracy, repeatability, size and

reliability. With their impressive dynamic capabilities and enhanced load

-carrying capacity, ANT95LZS stages are the premier choice when you

need superior quality vertical motion in a compact form factor.

Industry-Leading Motion Performance

Outstanding accuracy, position repeatability and in-position stability require

extremely fine system resolution. Available with an improved high-performance

encoder option, ANT95LZS can easily achieve minimum incremental steps of

1 nm. Our direct-drive technology exhibits no hysteresis or backlash, enabling

accurate and repeatable nanometer-scale motion. Plus, the minimally-influencing

counterbalance design opposes the gravitational forces induced by your payload,

resulting in industry-leading performance and optimum thermal stability.

Integrated Counterbalance

MPS-LZS stages are equipped with a minimally influencing pneumatic

counterbalance to offset the gravitational forces from the carriage and

payload. It includes a precision regulator for the exact dialing-in of the

counterbalancing force. Unlike spring or magnetic counterbalance

designs, the pneumatic counterbalance can be easily adjusted to exactly

offset your payload’s weight—no ballast or counterweights needed.

The counterbalance is installed standard on the left side of the stage;

however, you can easily reconfigure it for right-side operation.
