Abstract

Fig. 1 shows a molded chemical treatment arbor 1 has been placed in a chemical treatment basket 7. The arbor has a stainless steel rod 2 imbedded in the material to maintain the rigidity and increase the of the arbor during chemical bath immersion. The grooves 3 are made to exactly duplicate the diameter of the 95 mm disk substrate 4 to be worked. unique swing bail 5, shown in detail in Fig. 2, comes 0.020 inch of the inner diameter of the substrate 4. swing bail's main purpose is to maintain the 95 mm position in the holding groove 3. Without the bail, the 95 mm substrates will become dislodged the holding grooves and cause the disks to hit each in a destructive manner.

Swing Bail for Chemical Arbor

       Fig. 1 shows a molded chemical treatment arbor 1 has been
placed in a chemical treatment basket 7.  The arbor has a stainless
steel rod 2 imbedded in the material to maintain the rigidity and
increase the of the arbor during chemical bath immersion.  The
grooves 3 are made to exactly duplicate the diameter of the 95 mm
disk substrate 4 to be worked. unique swing bail 5, shown in detail
in Fig. 2, comes 0.020 inch of the inner diameter of the substrate 4.
swing bail's main purpose is to maintain the 95 mm position in the
holding groove 3.  Without the bail, the 95 mm substrates will become
dislodged the holding grooves and cause the disks to hit each in a
destructive manner.  The low mass of these parts such that the
environment of the chemical pretreatment is violent enough to move
them out of a holding  The swing bail 5 is formed from 0.125-inch
stainless steel.  This provides a surface has natural lubricity and
good flow dynamics.  The bail swings to the dash line upper holding
position 6 loading and unloading by simply rotating the arbor until
is completely upside down.
