4.2. Cleaning and Lubrication
O-rings and collet piston seals should be lubricated with with Parker O-Lube lubricant or an equivalent o-ring
lubricant. See Section 4.3.3. for details regarding lubrication of the wet cut rotary union seals.
Any metal parts may be cleaned with either acetone or isopropyl alcohol. Seals and o-rings may be wiped
with a small amount of isopropyl alcohol if necessary.
Acetone should never be used to clean the o-rings or seals.
4.2.1. Collet & Collet Chuck Lubrication and Cleaning
For the collet chuck and collet to operate properly, preventative maintenance and regular cleaning is
required.
Failure to lubricate and clean the collet interface surfaces will cause premature failure and
wear that can void the warranty.
Before inserting any collet into the chuck, clean the chuck taper and the collet with acetone or isopropyl alco-
hol with a lint free cloth a rag. If necessary, you can use compressed air to clean out the collet grooves.
Inspect the collet and the chuck interface surfaces to confirm that no marks are present. If wear or fret marks
(copper colored oxide marks) are present, you can lightly polish the taper with a fine grit crocus cloth. You
should clean the surface without removing an excessive amount of material. If the wear marks are large or
excessive polishing is required to remove these marks, the taper and the collet might need to be replaced.
Contact Aerotech customer service for more information.
After inspection and cleaning, grease the chuck taper and collet taper with a small amount of lubricant and
insert the collet. Table 4-1 shows the lubricants recommended by Aerotech.

Lubricant inspection and replenishment depends on conditions such as collet chuck duty cycle and the sur-
rounding environment. An inspection interval of once every eight hours is recommended until a trend devel-
ops for the application. Longer or shorter intervals might be required to maintain a film of lubricant on the
collet taper. Every time you remove a collet you should clean, inspect, and grease the collet and chuck inter-
face surfaces.
