How can Manhart (Guangdong) CNC Machine Tool Co., Ltd. avoid material deformation during laser cutting?

Material deformation during laser cutting is a common problem, but it can be avoided or reduced through a series of methods. Here are some suggestions:
1. * * Choose the appropriate material * *: Firstly, selecting high-quality materials suitable for laser cutting is the key to reducing deformation. Different materials have different characteristics such as thermal conductivity and coefficient of thermal expansion, so when selecting materials, their ability to resist thermal deformation should be considered.
2. Preheating treatment: Proper preheating treatment of the material before laser cutting can reduce deformation caused by laser heat. Preheating can make the material more evenly heated during cutting, reducing temperature difference stress.
3. * * Control cutting parameters * *: The speed, power, and focus position of laser cutting have a direct impact on cutting quality and material deformation. Adjust these parameters according to different material types and thicknesses to achieve the best cutting effect.
4. * * Increase fixation and support * *: Increasing the fixation and support of materials can reduce stress concentration during the cutting process, thereby avoiding or reducing deformation. For example, using fixtures or other devices to secure materials.
5. Reasonable arrangement of cutting sequence: When cutting materials with complex shapes, reasonable arrangement of cutting sequence can reduce deformation caused by thermal stress. The general principle is to first cut the external contour, and then cut the internal details.
6. * * Use auxiliary gas * *: During the cutting process, using auxiliary gas (such as nitrogen) can blow away melted metal, reduce the impact of heat on the material, and thus reduce deformation.
7. * * Subsequent Treatment * *: After cutting, the material can be subjected to appropriate post-treatment, such as annealing or heat treatment, to eliminate internal stress and reduce deformation.
8. Regular maintenance of equipment: Maintaining the good condition of laser cutting equipment is also an important factor in reducing material deformation. Regular inspection and maintenance of equipment can ensure the quality, accuracy, and stability of the laser beam.
In summary, avoiding material deformation during laser cutting requires comprehensive consideration of material selection, pretreatment, cutting parameter control, fixation and support, cutting sequence, use of auxiliary gases, and subsequent processing. Through reasonable operation and maintenance, material deformation can be minimized to the greatest extent and cutting quality can be improved.
