Roll Formers
Jet Engine Components
Roll forming is widely used to form profiles in turbine rings made from a variety
of materials such as, inconel, and titanium, and aluminum based alloys. Fontijne
Grotnes’ Roll Formers are used when fine detail and excellent surface quality are
required. They are capable of forming complex profiles with very high accuracy
and repeatability.
Applications
Profiled rings for the aerospace industry are formed on
Fontijne Grotnes Roll Formers.
Aerospace parts are made from tubing, pipe or coiled and welded blanks and are
formed on the Roll Former into straight sided cylinders or rings. Besides, these
rings can be expanded or shrunk on Fontijne Grotnes Expanders or Shrinkers.
Benefits
Perfect for both long production runs due to their highly accurate and repeatable operation as well as
for short runs due to their easily accessible tooling areas, which reduces set-up and tool change.
The single end design is also highly flexible. Single end machines can form a wide range of part
thicknesses, widths and diameters.
Once a group of parts with the same profile and material thickness is established, any part in that
group can be made with the same tooling. This efficient use of tooling keeps tooling costs and labor to
a minimum.

10-200 Roll Former
A 10 ton Roll Former. Both spindles are supported by a
swiveling arm, which is hinge mounted in the machine frame.
The lower spindle is actuated by a hydraulic cylinder operating
at two speeds, fast approach and in-feed speed. The position
of the upper spindle is adjustable for different tool diameters
by means of a jack. Both spindles are driven differential, to
equalize circumferential speed of top and bottom tooling.
This Roll Former has two side guides in order to keep the ring
positioned. The side guides are adjustable to different ring
diameters.
400 Roll Former with Bending Rolls
This machine can be used either as a Roll Former or as a
coiler. The long spindles accommodate several part sizes
on one single machine. The side guides accommodate
keeping the parts stable and providing coiling capability.
The position of the side guides is adjustable by hydraulic
motors.
Features
• Wide range of sizes and configurations
• Position control system
• User friendly touch screen interface
• Automatic lubrication system
• Automatic (un) loading
