Straightening machine are a key component in any coil feed line. These machines are used to straighten metals like steel and aluminum. Different metals have varying yield points and different thicknesses, so it is important to choose the right machine for your application.
Straighteners are equipped with a ‘zero’ or home position for the upper work roller depth setting. This is the point where the work roller is tangent to the lower fixed bank of rollers.

Metal straightening machines are used to straighten flat materials like metal sheets, wires, and pipes. These machines are also known as roller straighteners, and they work on the principle that material is led over a series of rollers to achieve straight or plane results. The rollers can be positioned at different angles to straighten the product in a single pass, or they can be positioned at an angle and straightened in multiple passes.
These machines can be powered or non-powered. Power straighteners tend to have higher speeds and can handle a variety of widths and thicknesses, but are typically more expensive. Moreover, power straighteners require more power than non-powered straighteners.
The process of straightening is complicated by the fact that the different metals have differing yield points, and they may require a slightly different approach to straightening. For example, steel requires lower temperatures than aluminum to be straightened. It is important to pay attention to these details to ensure that the straightening machine you choose meets your needs.

Straightening machines are heavy equipment used to give precision straightness to metal profiles, bars, tubes, and wire. They use a combination of pinch rollers, drag brake strength, and work roll depth settings to achieve the desired straightness. They can also be used to correct deformed products.
Different types of metals have different yield points and require a variety of work roll diameters to maintain the appropriate level of flatness. In addition, the maximum width of the material and machine should be taken into consideration when determining the machine’s capacity.
The upper work rollers of most straighteners are contained in precision guiding slide block assemblies. There are several methods for raising and lowering these assemblies, including fine threaded nuts and screw mechanisms, worm gear and screw mechanisms, and precision screw jacks. These assemblies help minimize the tendency of the work rolls to deflect and can also reduce the stress placed on the work rollers. This helps to prevent overstretch and cracking of the work rollers, which can result in poor straightener efficiency and slippage of the material.

Straightening machines are designed to re-establish the original flatness of extruded aluminum. The amount of work roller penetration required to achieve a specific level of flatness depends on the material type, thickness and width. This information is used to calibrate the upper work roll depth setting of the straightener. This is achieved through a combination of simple calibration tools like scales and pointers, or more sophisticated methods such as dial height indicators.
Thicker materials require fewer straightener work rollers, and their diameters and centre distance spacing are generally higher than those of thin materials. This ensures that the straightener’s work rollers are capable of back bending the material without excessive deflection across their width.
As a result, this requires more power from the machine’s drive motors. This can cause premature gear wear and stress on the machine’s journals. It is important to monitor the straightener’s performance and make necessary adjustments to prevent damage. This is especially true for aluminum-intensive vehicles, where the structural integrity of the vehicle is critical.

There are many different types of straightening machines available, each designed for a specific type of metal. However, effective results are contingent on correct and consistent set-up. This includes establishing pinch roll pressures, drag brake strength and work roller depth settings. The required settings can vary widely depending on the material thickness, width and coil set amount.
The resulting straightened product must be sufficiently flat to allow the material to stretch and compress evenly across its surface, without exceeding its yield point. Achieving this requires bending the metal around sets of rollers that alternately stretch and compress it. This process is known as forming.
In addition to straightening, the company offers finishing services including anodizing, powder coating, painting and heat treating. It serves aerospace, automotive, electrical, medical, railroad, semiconductor, transportation and military industries. Blanket orders are accepted and lean manufacturing and Kaizen/5S capabilities are offered. Finishing services are compliant with Mil-Spec and AS, ANSI and ASME standards.
