-ACS stages are equipped with ER25 or ER40 style collets. It is important that only the collets
designed for a particular collet holder are used. Contact the factory for more details.
N O T E : Aerotech recommends using only electro-polished collets manufactured to DIN6499 spec-
ifications.
N O T E : Various grip diameters are commonly available and can be interchanged following the collet
removal and installation procedure detailed in
2.5.1. Collet Installation and Removal Procedure
D A N G E R : To minimize the possibility of bodily injury or death, disconnect all electrical power
prior to making any mechanical adjustments.
Step 1: Remove power to the stage before installing or removing the collet.
Step 2: Apply air pressure to loosen the collet chuck.
Step 3: Remove the collet nut by turning it counterclockwise. If necessary, use a spanner wrench (available
from Aerotech).
Step 4: Clean the collet housing, collet nut threads, collet nut, and new collet. Acetone or isopropyl alcohol
may be used to clean the metal components. A small amount of any general-purpose, high viscosity
grease can be applied to the collet taper to help reduce friction and decrease wear.
Step 5: Refer to the instructions in
Step 6: Use the collet nut to guide the collet into the stage
erly in its taper. Be sure that air pressure is still being supplied to the stage so the collet chuck is in
the open position.
Step 7: Tighten the collet nut. Tightening by hand is sufficient as the clamping force is not determined by the
torque of the nut, but by the force of internal springs. Spanner wrenches may be used if desired.
Step 8: Restore power to the stage.
