Crimp Verification

Section 3

TAC

MANUAL

1. Introduction

2. Initial Crimp

Verification

Initial and periodic crimp verifications must be made in order to be certain
a given TAC is crimping properly. Once a TAC is set-up and crimp

verification accomplished, the device will normally complete hundreds of
thousands of acceptable crimps before indenter adjustment or

replacement is necessary.

However, as in all precision equipment, something can malfunction, or the

indenters may inadvertently be subjected to a hard substance and the

resulting crimp not meet acceptable parameters. Therefore, it is
recommended that the Crimp Verification procedure be performed at least

monthly. A system of "spot checks" can also be established to verify
acceptable crimps.

The Initial Crimp Verification should be performed immediately after the
TAC has been set-up (Section 2). Although the procedure is the same as

all other verification tests, it affords the user an opportunity to record data
before the machine has been used extensively. Read and understand

Section 4, Operating Procedures, before performing the verification. This
paragraph details the procedure to verify TAC's with a fixed "G" dimension

and with an operator-selectable "G" dimension.

Perform the following steps to verify acceptable crimps:

WARNING

Before the funnel cover plate or the cylinder arbor cover plate

is removed, DISCONNECT the air supply

from the sleeve valve. INJURY COULD RESULT ! !

Step 1.

Open the sleeve valve.

Step 2.

Disconnect the air supply from the sleeve valve.

Step 3.

Refer to Figure 3-1.

Step 4.

Remove the four button head socket cap screws securing the
crimp cylinder arbor cover plate.
