Note:
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. Maximum loads are mutually exclusive. Loading limits are due
to the collet chuck mechanism. Contact Aerotech directly if part
load requirement exceeds specifications.
4. Measured TIR of precision gage pin chucked with an ultraprecision
ER collet (DIN6499) 10 mm away from collet face with no load.
5. Collet chuck mechanism is normally-closed. Collet mechanism requires
air to open 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.
