Concentrated perforation

Centralized perforation, also called pre-perforation, is a processing technology, not a function of the machine itself, and requires the help of an automatic programming system when it is used. When laser cutting thicker plates, the cutting process of each contour has to go through two stages: 1. perforation and 2. cutting.
Centralized perforation can improve processing efficiency. With centralized perforation, the focus can be adjusted to the position suitable for perforation. After the perforation is completed, the machine is paused, and then the focus position is adjusted to the optimal position required for cutting. In this way, the perforation time can be shortened by more than half, greatly Improve efficiency.

It is also possible to adjust or change other process parameters between centralized perforation and cutting (for example, air + continuous wave can be used for perforation, and oxygen is used for cutting, and there is enough time to complete the gas switching).

Bridge position (micro-connection)

During the laser cutting process, the sheet is supported by a jagged support bar. If the cut part is not small enough, it cannot fall from the gap of the support bar; if it is not large enough, it cannot be supported by the support bar; it may lose its balance and lift up. The cutting head moving at a high speed may collide with it. If the cutting head is stopped, the cutting head may be damaged.
This can be avoided by using the bridge (micro-connection) cutting process. When programming the graphics for laser cutting, the closed contour is intentionally broken at several places, so that after the cutting is completed, the parts and the surrounding materials are stuck together, so that they will not fall.

These breaks are the bridge positions. Also called breakpoint, or micro-connection. The break distance is about 0.2 ~ 1mm, which is inversely proportional to the thickness of the sheet. Based on different angles, there are these different names: based on the contour, it is broken, so it is called a breakpoint; based on parts, it is bonded to the base material, so it is called a bridge or micro connection.
The bridge position connects the parts with the surrounding materials. The mature programming software can automatically add the appropriate number of bridge positions according to the length of the contour. It can also distinguish the inner and outer contours, decide whether to add a bridge position, so that the inner contour (waste) of the bridge position is not dropped, and the outer contour (parts) of the bridge position are adhered to the base material and do not fall, thereby eliminating Sorting work.

Coedge cutting

If the contours of adjacent parts are straight and have the same angle, they can be combined into a straight line and cut only once. This is co-edge cutting. Obviously, co-edge cutting reduces the cutting length. In addition, co-edge cutting does not require the shape of the part to be rectangular. Therefore, the processing efficiency is significantly improved.
