13.5.9 Clamp Position and Pressure
The workpiece is held to the table surface during operations by an air cylinder clamping system.
This system has multiple adjustments:
Horizontal Adjustment: Loosen the locking
13) and slide the clamps to
handles (A,
Fig.
any point along the beam (C, Fig. 13). Once
the clamps are properly positioned, securely
tighten the locking handles (A, Fig. 13)
Vertical Adjustment: The clamps can be
adjusted veritcally to suit the thickness of your
workpiece. Loosen the locking handle (A, Fig.
13)
and slide the clamp up or down as
desired. Re-tighten locking handle.
Parallel Adjustment: The beam (C, Fig. 13)
can be shifted to keep the clamping system in
line with the workpiece; for example, when using narrow workpieces. Loosen both locking handles
(B, Fig, 13) and slide the beam backward or forward as needed. When finished, always re-tighten
the locking handles (B, Fig. 13)
13.5.10 Parallelism of Boring Head to Table Surface
To ensure accurate hole centerlines in your
workpiece, the line of spindless must be parallel to
the table top. Check this setting and adjust if
necesarry:
• Remove fence and clamp assemblies. Remove
boring bits and chucks from the spindles.
• Pivot the boring head to horizontal position, and
lock it in position.
• Rotate the crank handle to bring the spindles up as
far as they will go.
• Insert two 10mm rods approximately 115mm long
into two quick release chucks. Mount one rod and
chuck to the center spindle, and the other rod and
chuck to the far left spindle. See Fig. 14
• NOTE: The 10mm rods must be used to ensure
accuracy in the measurements.
• Place a gauge block on the table and below the rod
of the center spindle, as shown in Fig. 14 (The
gauge block can be any size as long as it fits
between table and rod.)
