Fiber laser cutting machine uses a steel structure machine tool, the steel structure casts the entire fuselage, and also needs annealing process to ensure the stability of the laser cutting machine. Laser cutting, as a precision processing method, can cut almost all materials, including two-dimensional cutting or three-dimensional cutting of thin metal plates.

1. Fiber laser cutting machine tool annealing concept

The annealing process is to heat the steel to a specific high temperature and keep this temperature for a period of time, and then let it cool slowly. The annealing of steel is a heat treatment method that heats the steel to a temperature where phase change or partial phase change can occur, and then slowly cools it after insulation.

2. Purpose (function) of fiber laser cutting machine tool annealing

The purpose of annealing is to reduce organizational defects, improve the organization to make the composition uniform and refine the grains, increase the mechanical properties of steel, and reduce residual stress; at the same time, it can reduce hardness, increase the plasticity and toughness of the laser cutting machine tool, and improve cutting performance. Therefore, annealing is not only to reduce the organizational defects and internal stress generated by the previous process, but also to prepare for the subsequent process.

Taking necessary heat treatment processing is of great help to the later use. Considering the on-site processing environment of the enterprise and the main use of CNC cutting machine as the primary processing equipment of materials, improving some physical properties of the metal fiber laser cutting machine body is also an important means to extend the service life of the equipment, so the annealing process of the metal laser cutting machine is indispensable.

Laser cutting replaces the traditional mechanical knife with an invisible beam. It has the characteristics of high precision, fast cutting, not limited to cutting pattern restrictions, automatic typesetting to save materials, smooth incision, low processing cost, etc., and will gradually improve or replace the traditional metal cutting process equipment.

Fiber laser cutting machine laser cutting has no contact with the workpiece and will not scratch the surface of the workpiece during work; laser cutting speed is fast, the incision is smooth and flat, and generally no subsequent processing is required; the cutting heat affected zone is small, the plate deformation is small, and the cutting seam is narrow (0.1mm~0.3mm); the incision has no mechanical stress and no shear burrs; the processing accuracy is high, the repeatability is good, and the material surface is not damaged.
