Oakley Industrial Machinery’s automatic cutting-from-coil line is engineered for high-volume heating elements production, providing a fully automated solution for cutting tubes from coil with remarkable speed and precision.
This advanced system processes stainless steel tube coils through multiple integrated units, including decoiling, calibrating, and straightening sections equipped with hyperbolic rolls to ensure flawless tube alignment before cutting.
At the core of the system is a high-performance cutting unit, available with either a score-and-pull-apart mechanism, saw-cutting configuration or a guillotine cutting system. Once the operator sets the feed rate, batch size, and tube cutting length via the control interface, the line operates autonomously—guaranteeing continuous, efficient production.
The concrete advantages that make the difference
Designed for continuous operation and large production batches.
Set parameters once and let the system handle the entire cycle.
On-the-fly cutting ensures fast, precise tube processing for heating element manufacturing.

DOUBLE STRIP DE-REELER
With the possibility of loading two tube coils, allowing continuous operation without stopping the machine during coil replacement.
CALIBRATION SYSTEM
The machine is supplied with two calibration heads. The heads are idle. When processing tubes with different diameters, it is recommended to purchase additional calibration units complete with base, roll supports, and rolls in order to minimize changeover time. Otherwise, for each diameter change it is necessary to replace the rolls and guide bushes in the calibration system.
ELECTRIC CONSOLE
Electrical cabinet and operator console complete with touchscreen display, where the operator can program the tube cut length, the number of pieces to be cut, and the line speed.
UNLOADING HOPPER
TRACTION SYSTEM (CATERPILLAR)
This device has two rubber-lined tracks that pull the tube from the de-reeler and feed it through the calibration unit and into the straightening device. The upper track can move upward (open) or downward (closed or running position) by means of a pneumatic cylinder. The pressure applied by the cylinder can be adjusted to suit the tube diameter and wall thickness. As standard, the upper track is motorized, but it is also possible to motorize the lower track with a minor modification.
STRAIGHTENER
Rotating straightener with five pairs of idle hyperbolic rolls.
ON-THE-FLY CUTTING SYSTEM
In this device, the cutting unit is integrated into a mobile carriage with a controlled axis.

The orbital score-and-pull-apart system is engineered to address the limitations of similar orbital cutting methods that rely on engraving wheels. This process employs either a rotary blade cutter or insert-style cutting technology to gradually score the tube, thinning a circular section of its wall. Once sufficiently weakened, a clamp separates the tube cleanly. The result is a chipless, burr-free cut with perfectly smooth edges and no deformation.
The saw-cutting system uses a high-resistance circular blade that spins at high speed to deliver fast, clean cuts. This technology can handle various tube thicknesses and materials while maintaining precise 90-degree cutting accuracy. In addition, the sturdy construction and cutting method increase the tool’s lifespan, providing long-lasting durability and dependable performance.
Guillotine cutting lines are engineered to produce tubes in customized lengths, with the internal diameter precisely calibrated at both ends. These systems are typically chosen for medium- to high-volume production, as they allow fast changeovers between cutting diameters. After cutting, a punching step removes the “heart-shaped” deformation created by the process. This punching can be carried out manually using a handheld tool or automatically through a transfer system positioned after the cutting station.
