Laser cutting is one of the thermal cutting methods. What is the annealing process of the laser cutting machine machine tool? What is the function of the annealing process? Qiaolian Cylion will analyze and answer it for you. Tell everyone about the annealing process and function of metal laser cutting machine.
Laser cutting uses a high power density laser beam to irradiate the material to be cut, so that the material is quickly heated to the vaporization temperature, and evaporates to form holes. , to complete the cutting of the material.
Laser cutting process replaces the traditional mechanical knife with invisible beam. It has the characteristics of high precision, fast cutting, not limited to cutting pattern, automatic typesetting to save materials, smooth incision, low processing cost, etc. It will be gradually improved or replaced in Traditional metal cutting process equipment.
Analysis of annealing process and function of laser cutting machine machine tool:
The laser cutting machine adopts a steel structure machine tool, and the steel structure casts the entire body, and also requires an annealing process to ensure the stability of the laser cutting machine. As a precise machining method, laser cutting can cut almost all materials, including two-dimensional or three-dimensional cutting of thin metal sheets.
1. The concept of machine tool annealing
Annealing is the process of heating steel to a certain high temperature and holding it for a period of time, and then allowing it to cool slowly. The annealing of steel is a heat treatment method in which the steel is heated to a temperature where phase transformation or partial phase transformation can occur, and then slowly cooled after heat preservation.
2. Purpose (function) of machine tool annealing
The purpose of annealing is to reduce structural defects, improve the structure to homogenize the composition and refine the grains, increase the mechanical properties of the steel, and reduce the residual stress; at the same time, it can reduce the hardness, increase the plasticity and toughness of the laser cutting machine, and improve the cutting performance. Therefore, annealing is not only to reduce the structural defects and internal stress generated by the previous process, but also to prepare for the subsequent process.
Taking the necessary heat treatment processing is of great help to the later use. Considering that the on-site processing environment of the enterprise has already used the CNC cutting machine as the main purpose of the material initial processing equipment, improving some physical properties of the metal laser cutting machine body is also to prolong the use of the equipment. It is an important means of life, so the annealing process of metal laser cutting machine machine tools is indispensable.

Laser cutting has no contact with the workpiece, and will not scratch the surface of the workpiece during work; the laser cutting speed is fast, the incision is smooth and flat, and generally no follow-up processing is required; the cutting heat-affected zone is small, the plate deformation is small, and the slit is narrow (0.1mm~ 0.3mm); the incision has no mechanical stress, no shear burr; high processing accuracy, good repeatability, and no damage to the surface of the material.
