Bending Machines: A Comprehensive Guide - Baison Laser

However, selecting the ideal bending machine for your specific business needs can prove to be quite a challenge.

This article breaks down the core elements of metal bending machines, illustrating the range of types, applications, and advantages associated with them.

What are Bending Machines?

Bending machines are specialized tools used in metal processing that bend, shape, and curve parts at various angles. The bending process typically employs a cold working technique, which gently stretches the metal to achieve the desired angle. In some cases, the use of machine oil or lubricant is necessary to minimize the friction between the workpiece and the die press.

The hallmark of a high-quality bending machine lies in the uniform distribution of pressure across the surface of the metal workpiece. Ensuring equal and consistent force application mitigates the risk of metal fatigue and accidental breakages.

These bending machines boast nearly universal compatibility with different metals, capable of bending not just soft metals like copper and aluminum, but also tougher materials such as stainless steel and titanium.

How Does a Bending Machine Work?

The operation of a bending machine generally depends on its type. For instance, press brake-type bending machines utilize a punch-and-die mechanism to mold sheet metal, while pipe-bending machines employ a series of two to three rollers that stretch and form the pipe.

Regardless of the specific machine, the underlying principle remains coherent: to start the bend, two controlled opposing forces must be applied at a concentrated point on the metal workpiece.

Further details on the various metals processed by these machines will be elaborated upon later in the article.
