CML USA supplies a wide range of Ercolina
pipe benders, tube benders and tooling
for round or square tube, including the
Megabender ® 030 rotary draw bender with
internal mandrel.
Ercolina’s patented mandrel system
adapts easily to the Megabender
030 without
modification, to
produce high
quality bends on
tube and hollow
profiles when non-
mandrel systems
are no longer
effective.
Depending on
the material, wall
thickness and
distance between
bends, the Ercolina mandrel system can
accommodate centreline bend radii as
small as 1.5 times the external diameter, on
tube diameters ranging from 3/8" to 3".
Mandrel bend systems incorporate six
separate tools to effectively support the
profile during the bending process. The six
tools are the centre former, pressure die,
clamping die, wiper die, collet and internal
mandrel, and are specific to material type
and dimension.
Traditional mandrel machines require high
volume production to be cost effective.
The Ercolina system is an inexpensive
alternative to high volume systems, making
it suitable for prototype or production runs
requiring up to 1,000 bends per day.
The Megabender’s main drive unit is
electromechanical, which improves
reliability and reduces the cost and
maintenance requirements associated
with more expensive
completely hyd-
raulic systems.
The simple
hydraulic system
operates only the
clamp die, pressure die
and mandrel extractor.
Ercolina’s standardmicro-
processor controls clamping,
mandrel movement, bending speed,
bending angle and material spring back
compensation functions for true NC semi-
automatic three axis operation. Newly
redesigned mandrel tables are available
in 5, 10 or 20ft lengths, to accommodate
most applications.

Omni-X Inc, USA and Czech Republic,
is the manufacturer of high precision
and performance tube bending tooling
for the aerospace, automotive, shipyard,
HVAC, furniture and bathroom accessory
industries. The range includes bending and
end forming tools for any size, make and
model of tube bender and endformer on the
market.
Bend dies, clamp dies and pressure dies
are developed using the latest software and
over 80 years of combined experience in
the tube bending industry. The company’s
engineering department is capable of
designing both simple and complex
compounds and stackable multi-radius
bend dies in minutes. Quick change design
minimizes downtime between tool changes,
grip sections for all applications (serrated,
knurled, smooth, grit-blast) and mandrel-
less tooling.
Mandrels and wipers for any shape and
size are available using a variety of
materials and coatings, including round,
square, rectangle, oval and extrusion.
The most popular mandrel sizes and
components (shanks, balls and links) are
stocked in Ampco bronze and chrome,
ready for immediate shipping. Customer
tailored stocking programs are available
for mandrels, squareback and disposable
inserted wipers.
End forming and finishing tools consist of
custom and off-the-shelf applications for E/
R and ID/OD tools, ram form dies, flare dies
and flare centres, bead dies, heads, arbors
and tips.
