Purpose
This adjustment sets the distance between the anvil and the cutter former
(window opening). This dimension determines lead length that extends from
the bottom of the board.
Prerequisites:
Cutter Head is removed from the Clinch Base
Special Tools:
Vernier calipers
Comments:
• The anvil opening can be set from 0.060 to 0.090 inches and both
sides should be ± 0.001 inches.
• The lead length and angle are adjustable. For example:
Cutter Head
0° Position
.070 ± .010 in
(1.78 ± 0.25 mm)
52° ± 33°

• Lead lengths of up to .060 in (1.52 mm) are dependent on the
diameter of the lead, lead material, and the size of the hole in the
workboard (PCB).
• A larger window opening = longer lead length and decreased angle.
• Minimum Opening = .060 in (1.5 mm)
• Clinch Head Height Adjustment affects lead length and angle.
• Lead angles, lengths and heights vary based on PC Board
– hole spacing
– hole diameters
– component lead diameters
– component lead material
– composition
– lead shape (round, square, or flat).

Procedure:
1. Power down the machine and perform Lockout/Tagout according to local procedures.
WARNING The machine must be powered down and the local Lockout/Tagout
procedure performed to ensure personal safety during this procedure.
2. Remove the 4 screws securing the cutter head to the clinch base and remove the cutter head from the machine.
3. Loosen socket set screw as shown below. The continuity gap (see VSL
T Continuity Gap Adjustment in this module) may have to be opened
in order to make this adjustment.
