1. Collet chuck accepts Rego-Fix ER collets manufactured to DIN6499 specifications only.

2. Maximum speed based on stage capability; maximum application velocity may be limited by system data rate, system resolution, and load.

3. Repeatability and accuracy are dependent on encoder resolution. To achieve the listed specifications, encoder resolution must be 0.36 arc sec or less.

4. Maximum loads are mutually exclusive. Loading limits are due to the collet chuck mechanism. Contact Aerotech directly if part load requirement exceeds specifications.

5. Measured TIR of precision gage pin chucked with an ultraprecision ER collet (DIN6499) 6 mm away from collet face with no load.

6. Collet chuck mechanism is normally-closed. Collet mechanism requires air to open collet chuck. Air supply must be dry (0ºF dew point) oil-less air OR 99.99% pure

nitrogen. Air or nitrogen must be filtered to 1 micron particle size or better.
