Granite is a popular material used as a base for laser processing products due to its high stability, strength, and density. However, despite its many advantages, granite can also have some defects that can impact laser processing products. In this article, we will be exploring the defects of using granite as a base for laser processing products.
The following are some of the defects of using granite as a base for laser processing products:
1. Surface Roughness
Granite can have a rough surface, which can affect the quality of laser processing products. The rough surface can cause uneven or incomplete cuts, leading to poor product quality. When the surface is not smooth, the laser beam may get refracted or absorbed, leading to variations in the cutting depth. This can make it challenging to achieve the desired precision and accuracy in the laser processing product.
2. Thermal Expansion
Granite has a low thermal expansion coefficient, which makes it susceptible to deformation when exposed to high temperatures. During laser processing, heat is generated, leading to thermal expansion. The expansion can affect the stability of the base, leading to dimensional errors on the processed product. Also, the deformation can tilt the workpiece, making it impossible to achieve the desired angle or depth.
3. Moisture Absorption
Granite is porous, and it can absorb moisture if not sealed correctly. The absorbed moisture can cause the base to expand, leading to changes in the machine's alignment. Also, moisture can cause rusting of metal components, leading to the degradation of the machine's performance. When the alignment is not correct, it can affect the laser beam quality, leading to poor product quality and accuracy.
4. Vibrations
Vibrations can occur due to the laser machine's movement or external factors such as the floor or other machines. When vibrations occur, it can affect the base's stability, leading to inaccuracies in the processed product. Also, vibrations can cause misalignment of the laser machine, leading to errors in the cutting depth or angle.
5. Inconsistencies in Color and Texture
Granite can have inconsistencies in color and texture, leading to variations in the product's appearance. The differences can affect the product's aesthetics if the inconsistencies are visible on the surface. Additionally, it can impact the laser machine's calibration, leading to variances in the cutting depth and angle, causing inaccurate cuts.
Overall, while granite is an excellent material for a base of a laser processing product, it can have some defects that need to be considered. However, these defects can be minimized or prevented by proper maintenance and calibration of the laser machine. By addressing these issues, granite can continue to be a reliable material for the base of laser processing products.
