Aerotech’s CCS series rotary stages (patent pending) with integrated captured collet chucks provide automated material handling capability for a wide range of materials and applications.
High Precision C/D Collets
The collet chucks on the CCS family of stages accept C (for CCS190DR) or D-style/Levin (for CCS130DR) collets. These collets are readily available from machine-tool component suppliers in sizes that support tube diameters from 0.1 mm to 27 mm and provide outstanding run-out characteristics for applications requiring high-precision gripping of tubular material.
Captured Collet Design
CCS features a unique collet-chuck design that allows workpiece advance without manual realignment to compensate for axial tube motion during clamp/unclamp cycles. By moving the taper around the collet instead of drawing the collet into the taper, axial motion of the workpiece is significantly reduced, eliminating the need for part re-registration after tube advancement.
The CCS family is designed with mounting features on the housing to support customer supplied wet-cutting accessories. In addition, the stage is designed to tolerate moderate fluid leakage into the aperture, which is inevitable during wet-cutting operations, to prevent encoder contamination and collet-chuck failure.
To maximize positioning performance the CCS series uses direct-drive brushless motor technology. Direct-drive technology is optimized for 24/7 production environments, with 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.
The low maintenance, high throughput characteristics of the CCS coupled with the integral material handling capability provide the lowest total cost of ownership when compared to component-level solutions.

- Calibrated accuracy requires the use of Aerotech controls and angular programming units.
- Maximum speed listed is stage and motor dependent (assuming a 340 V bus). Actual speed may be lower due to motor back emf. Consult Aerotech for more details.
- Dry-Cutting (no ring seal installed) on a system with the -WC option limits tube size to 6.7 mm. Wet-cutting (ring-seal required and installed) on a system with the -WC option limits tube size to 3.0 mm.
- Maximum loads are mutually exclusive. Loading limits are due to the collet chuck mechanism. Contact Aerotech directly if part load requirement exceeds specifications.
- TIR of precision gage pin in an ultra-precision collet. Measured 3 mm away from collet face at 80 psig applied air pressure for CCS130DR. Measured 6 mm away from collet face at 40 psig applied air pressure for CCS190DR.
- The CCS190DR-260 and CCS190DR-240 contain a double-acting collet mechanism that requires air to open and close the collet chuck. Aerotech recommends compressed air filtered to 0.25 micron particle size or better.
- The CCS130DR-160 contains a collet chuck mechanism that is normally-open. Collet mechanism requires air to close collet chuck. Air supply must be dry (0º F dew point), oil-less air or 99.99% pure nitrogen. Air or nitrogen must be filtered to 0.25 micron particle size or better.
- Exceeding the maximum system air pressure on the CCS190 stages is not recommended and could cause damage and/or performance degradation.
