LAYOUT OF CONICAL ANGLES
Conical bending operation is performed by the conical bending system inside the machine.
Conical bending operation is the hardest operation amongst bending operations. Therefore,
operators who would be performing this operation shall be very experienced.
YOU SHALL USE HALF OF THE CAPACITY OF THE MACHINE.
This means that machine can bend only half of its capacity.
And, this is 1000mm x3mm. In other words, if the capacity of the machine is 2000x 6mm, it
can bend 1000mm x3mm.
If you want to obtain shortened cones as shown in the figure below, you shall be prepared as
per the angle position, length and diameter of the material; angle positions shall be
prepared according to the formulae below.

𝑆 = 𝐷 𝑥 𝜋
CALIBRATION
After the bending operation, diameter of the material that has been transformed to a
cylinder may not be fixed. Ovalness may be observed. Correcting the diameter and making
the cylinder circular as much as possible is performed by calibration.
OPERATION PROCEDURE
Bent material shall be removed from the machine and welded. Welding points shall be
cleaned by removing the burrs both from inside and outside. Welded cylinder is placed on
the machine again.
