What is the difference between different mesh number

Dec 27,2023

In the context of bead blasting in CNC services, the terms "80 mesh," "100 mesh," "120 mesh," and "150 mesh" refer to different grit sizes or particle sizes of the blasting media used in the process. The mesh size indicates the number of openings per linear inch in a sieve through which the blasting media passes. Here's a general overview of the differences:

bead blasting grit size

80 Mesh:

Larger particle size.

Removes heavy coatings, rust, and contaminants more aggressively.

Leaves a coarser finish on the material being blasted.

Suitable for applications where surface roughness is acceptable or even desired.

100 Mesh:

Medium particle size.

Balances between aggressiveness and surface finish.

Effective for general-purpose cleaning and preparation.

Provides a compromise between the coarser 80 mesh and the finer options.

120 Mesh:

Smaller particle size.

Removes lighter coatings and contaminants.

Offers a smoother surface finish compared to coarser grits.

Suitable for applications where a finer finish is desired.

150 Mesh:

Fine particle size.

Removes very light coatings and provides a smoother surface.

Ideal for applications where a high-quality, polished finish is required.

Used for precision cleaning and finishing.

The choice of mesh size depends on the specific requirements of the project, including the material being blasted, the desired surface finish, and the level of precision needed. Finer mesh sizes generally result in smoother finishes but may take longer to achieve the desired cleaning or texturing effect. It's essential to consider the material's sensitivity to abrasion and the final aesthetic or functional requirements of the part being processed.
