7.1 6 X 6 ANGLE SHEAR
The 6 x 6 angle shear is a component tool designed to shear angle iron. It installs in the tool station on
this machine and has a maximum capacity of 6 x 6 x 3/8 or 5 x 5 x 1/2 inch (150 x 150 x 9.5 or 125 x 125
x 12mm) mild steel angle iron. The selector switch must be in the SHEAR position to operate this tool.
7.1A 6 X 6 ANGLE SHEAR INSTALLATION
SEE FIGURE 14 ON THE FOLLOWING PAGE.
The 6 x 6 Angle shear mounts in the tool station under the upper arm.
1. Before mounting the tool under the arm, remove the upper blade and install the return springs
(A).
2. The selector switch must be in the SHEAR position and the arm up.
3. Slide the tool under the arm, as close to the machine’s frame as possible.
4. The tool is held in place with the finger clamps (B) provided.
5. Care must be taken to align the slug slot in the angle shear with the slot in the tool table and the
pressure block squarely under the power arm.
6. The upper stroke of the machine should be set so that the upper blade raises high enough to slide
the workpiece freely through the unit. The lower stroke should be set so that the upper blade point
enters the lower blades approximately 1/8 inch (3mm).
7.1B 6 X 6 ANGLE SHEAR OPERATION
Oil must be applied to the blades before the first cut is made and every 10 to 15 cuts, thereafter.
Grease the slider block between the upper arm and the tool every two hours of operation. A set of lower
blade shims are shipped with each unit. These are to be installed between the lower blades and the side
plate when shearing lighter angle (up to 5/16 of an inch (8mm) thick). If a burr develops when shearing
very light gauge angle, the clearance should be reduced further by adding additional shim stock. All
shims must be removed when shearing angle thicker than 5/16 of an inch (8mm).
When cutting angle iron with legs of unequal length, a special upper angle shear blade is necessary.
Do not attempt to cut unequal leg angle iron with the standard blade. It only takes one cut to
damage the tool.
For available blades, SEE THE TOOLING PARTS MANUAL.
NOTE: Always shear unequal leg angle with the long leg to the right. If the upper blade does not
contact both legs of the angle at the same time at the beginning of the cut, the shear will be
damaged.
