Anhui sheet metal fabrication manufacturer Introduction to how to select the laser cutting piercing points when performing sheet metal fabrication.
Aluminum sheet cutting using laser cutting technology is relatively uncommon in the field of sheet metal fabrication or aluminum sheet processing. Compared to traditional mechanical cutting methods, laser cutting offers advantages such as high precision, fast cutting speed, and high efficiency. However, fiber laser cutting requires specialized auxiliary equipment, which increases its overall cost. The working principle of fiber laser cutting is as follows: During the aluminum sheet cutting process, the laser beam creates indentations on the surface of the aluminum sheet. Subsequently, the laser diode performs the cutting operation, and these indentations gradually deepen and transform into small circular holes.
Laser perforation and wire-cutting hole preparation are similar. In laser processing, these holes serve as starting and ending points for contour laser cutting. Typically, the laser's travel path is perpendicular to the tangent direction of the cutting contour on the workpiece. During laser cutting, it’s crucial to pay attention to the direction of the laser beam and ensure that the cutting process is continuous and uninterrupted. Never abruptly jump from one position to another—doing so can easily result in numerous tiny circular holes during aluminum profile laser cutting, thereby compromising the overall quality of the laser-cutting process.
Every fiber laser cutting process is governed by strict safety operating procedures and protocols. However, fiber laser cutting is not as complicated as one might imagine. Nowadays, fiber laser cutting systems are equipped with highly precise control systems that interface with software, forming a human-machine interaction interface. By simply setting the relevant key parameters, the system can automatically determine the piercing points and carry out laser cutting according to the specified orientation. Fiber laser cutting boasts high precision—significantly superior to manual laser cutting. Manual laser cutting is typically used for processing relatively complex workpieces, since fiber laser cutting machines, due to their intricate shapes, cannot automatically locate piercing points. Therefore, sheet metal fabrication companies can also draw corresponding cutting diagrams when determining piercing points, ensuring that the quality of laser cutting and hole-punching operations is foolproof.

Anhui sheet metal fabrication manufacturer Today, sheet metal fabrication can be divided into three types.
1. Pneumatic configurations of components, including the aircraft fuselage, aircraft wings, tail section and ducts, rocket combustion chambers, and nozzles.
II. Sheet-metal fabricated parts primarily refer to various frame components, such as precast members oriented vertically, horizontally, and diagonally—including beams, longitudinal girders, partition wall structures, and stiffening plates, among others.
Third, this includes certain embedded components in systems such as fuel systems, operational systems, and communication systems, as well as many sheet-metal fabrication components used in routine maintenance equipment—such as oil tanks, various pipelines, supports, seats, and the like. The selection of processing technologies varies depending on the type of part being manufactured.
Nowadays, when manufacturing sheet-metal parts, Anhui sheet-metal processing manufacturers not only continue to employ the commonly used cold-stamping method in mechanical equipment production but also extend its application to other forming techniques. For example, plastic hydraulic forming typically involves injecting tire rubber into a container under high pressure, causing it to expand, and then using a mold that matches the shape of the tire to press the blank material into the desired part.
Another forming process is called stretch-bend forming. When using this process to work on sheet metal, the blank is first stretched along its length and width until it reaches its tensile strength limit. Then, the tensile force is maintained, and the blank is bent according to the surface profile of the stretch-bend die. This method can improve the forming accuracy of the part.
