PREPARATION FOR SELF PROPELLED OPERATION
The Gullco KBM
®
-28 Plate Edge Bevelling Machine is typically used with an optional hydraulic
adjustable lift undercarriage with self-aligning spring loaded caster wheel assemblies for self-
propelled operation. I.e. the material stays stationary while the bevelling machine propels itself
down its edge. This system is employed for bevelling large and heavy plate materials which cannot
be fed through the machine. When both the machine and material are properly set up, as described
below, the cutter will drive the machine on its caster mount, along a floor or runway.
Plate materials should be secured on a work table/platform that is of an appropriate height above
the floor, or runway, for the angle of bevel to be performed. See the table below for minimum plate
heights.
KBM ® -28 MINIMUM WORKING HEIGHT when used with KBM-28-080 Undercarriage Assembly
DEGREES *TABLE HEIGHT
22.5º
35” [889 mm]
30º
37.5º
45º
55º
* This is an absolute minimum height and should be used as a guide only. Most bevelling will
be 1/2” [12.7 mm] to 1” [25.4 mm] higher than above.
IMPORTANT: KBM
®
-28 Undercarriage Assembly is equipped with spring loaded casters
designed to accommodate slight floor to work table height variances, however,
if the table height (work-piece) becomes too low (springs unable to compress
any more), machine damage will likely occur.
PREPARATION FOR BENCH OPERATION
The Gullco KBM
®
-28 Plate Edge Bevelling Machine may be used as a bench/floor mounted rotary
shear for bevelling small, light and manually manageable work pieces. For bench/floor mounted
applications, the optional Base Frame and spring loaded caster assemblies can be removed from
the machine (if applicable). To establish an efficient, safe working position, mount the bevelling
machine to a levelled bench, or work table, capable of handling the load involved, or to the floor. It
is always advisable to tilt the mounting of the bevelling machine to allow the work pieces to remain
in a flat, horizontal plane. It is not recommended to bevel heavy or large work pieces that are
difficult to manually handle, with bench/floor mounted machines. If a heavy or large piece must be
bevelled with a bench/floor mounted machine, support the material with a suitable arrangement of
rollers or casters to allow free movement of the material. Ensure that the work piece is level with,
and sits flat on, the Main Roller and Support Rollers.
IMPORTANT: Heavy work pieces being bevelled on bench / floor mounted machines can
cause a twisting force on the cutter and may lead to cutter / machine damage.
IMPORTANT: Make sure all plates are started square to the cutter, or damage could result.
