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.

Brushless Direct-Drive

The ASR1100 series uses direct-drive brushless motor technology to maximize

precision and speed. Direct-drive technology is optimized for 24/7 production

environments because there are no brushes to replace and no gear trains or

belts to maintain. Direct drive also provides quicker acceleration and higher

top speeds than gear- or belt-driven mechanisms, yielding higher total overall

throughput. This makes the ASR1100 an excellent choice for processing

cylindrical and tubular materials. The ASR1100’s low maintenance and high

throughput characteristics provide a stage that yields the lowest total cost of

ownership.

Compact Size & Dynamic Performance

The ASR1100’s design optimizes speed and throughput by minimizing the

stage’s weight and rotating inertia. With a net overall weight under 5 kg, the
