Groove Cutting Technology Overview

The development of large groove cutting machines

In the hot cutting industry, in recent years, with the development of 5-axis linkage CNC technology, height adjustment technology, groove nesting technology, and rapid accuracy recovery technology, laser groove cutting has made breakthrough progress, and large-area laser groove cutting machines are gradually developing.

The requirements for operators and maintenance personnel of the new generation CNC fiber laser groove cutting machine have been greatly reduced, and the vast majority of technical personnel with simple foundations can quickly master this technology.


Introduction to groove types

Laser cutting, as an important technology in modern mechanical processing and manufacturing industry, occupies an important position in groove processing due to its accuracy and efficiency. Beveling is a crucial step in welding technology, which is of great significance for improving welding quality and efficiency. Below, we will analyze several types of groove types commonly used in laser cutting in the mechanical processing and manufacturing industry.


Firstly, let’s talk about the “V” groove. This is one of the most common types of grooves in laser cutting, suitable for materials of various thicknesses. Its shape is similar to the English letter “V”, and the angle and depth of the groove can be adjusted as needed. By laser cutting, a V-shaped groove can be quickly and accurately processed, providing convenience for subsequent welding work.


Secondly, the U-shaped groove is also a commonly used type in laser cutting. Compared with the V-shaped groove, the U-shaped groove has a deeper opening and smoother transition, which is conducive to the melting and flow of metal during welding. In situations where high stress is required or the weld seam requires high strength, a U-shaped groove is a good choice.


In addition, the “J” groove is also a common groove type in laser cutting. Its shape is similar to the English letter “J”, with a wide opening and a narrow bottom, suitable for situations that require high welding strength and aesthetics. Laser cutting can accurately control the shape and size of J-shaped grooves, ensuring welding quality.


In addition to the common types of grooves mentioned above, laser cutting can also process other shapes of grooves according to actual needs, such as “X” type, “K” type, etc. These groove types have unique advantages in specific application scenarios and can be selected based on specific welding processes and material characteristics.



Most types of grooves required for welding can be cut using laser groove cutting machines. Greatly promoted the smooth production of mechanical manufacturing companies. Previously, production that required multiple processes could be completed at once in the cutting process, greatly saving labor, space, transportation, secondary processing, and other work.
