GENERAL DESCRIPTION
The Gullco KBM
®
-28 Portable Plate Edge Bevelling Machine is an electrically powered rotary shear.
It is used to bevel a wide variety of plate edges, usually for the purpose of a weld joint preparation.
It is designed for one-man operation and is capable of bevelling straight or circular plate sections at
a speed of approximately 10’ [3 m] per minute
‡ . It is capable of performing multi pass bevelling for
larger bevels that cannot be accomplished in a single pass. Easy adjustment is provided for
altering the depth and angle of bevel.
A push button, mechanical starter complete with short circuit, motor overload and also under-
voltage protection, is used in conjunction with a directional selector switch, to start and stop a 3
H.p., 3 phase motor, which in turn uses a heavy duty industrial type gearbox assembly to drive a
serrated cutter. This cutter provides the "Rotary Shearing" as well the tractive effort to propel either
the plate through the machine, or the machine along the plate, depending on the application.
The KBM
®
-28 is typically equipped with an optional undercarriage assembly with individual spring
loaded casters that allow the machine to roll along the floor, or runway, during the bevelling
operation. Alternatively, the KBM
®
-28 machine could be bench mounted for applications where the
plate sections are small enough to manually feed through the cutter. The adjustable bevelling head
enables the bevelling of angles 22.5° through 55°.
The KBM
®
-28 is available for use with the following power supplies; 230, 460 and 575 V at 60 Hz.
and also 380 and 400/415 V at 50 Hz. The supply to be used must be specified at the time of order.
Gullco can also provide machines for use with supplies that are not listed above, please consult
Gullco for more details.
The KBM
®
-28 machine comes complete with a tool box which includes the bevel angle pins 22.5°,
30°, 37.5°, 45°, and 55° as well as all of the necessary wrenches and hexagonal keys that are
required to make adjustments to the machine.
Note: The machine is shipped from the factory with the 30° bevel angle pin in place.
INTENDED / FORESEEN USAGE
The Gullco KBM
®
-28 Portable Plate Edge Bevelling machine is used throughout the world to
automate and improve the quality and efficiency of the weld preparation required for manual,
semiautomatic and fully automatic welding operations.
It provides industry with a highly efficient, practical and truly portable method of producing straight
machined bevels on a wide variety of plate materials, including mild steel, stainless steel and
aluminum..... effectively meeting V, X or K weld joint preparation requirements.
Loss of production through operators suffering from skeletal, muscular and hearing loss injuries
normally associated with pneumatic and hand held milling type bevelling equipment is greatly
reduced and detrimental factors such as operator fatigue, or inconsistent workmanship are
eliminated. Required quality levels are consistently attained and productivity and profitability
increased.
‡
Top speed can vary depending on variations of bevel depth, voltage and frequency.
