What is glass bead blasting?

What is glass bead blasting?

Bead blasting is one type of shot blasting. This process releases, at high pressure, fine glass beads to clean or finish a surface. In this process, a bead blaster shoots bead-shaped media from a high-pressured tool towards the material’s surface. A bead blast finish aims to leave a smooth, shiny, and cleaner surface.

What grit is glass bead media?

50 Micron 240 Grit. High quality blast media. Spherical bead shape. Ideal for surface texturing, cleaning, peening, etching, and deburring various surfaces.

What is #8 glass bead?

8 is the most commonly used glass bead size. The MIL-PRF-9954B spec is for glass beads used for cleaning and peening, approved for use by all Departments and Agencies of the Department of Defense.

How is Blast Media measured?

In the U.S., the depth profile is measured by mils – thousandths of an inch. In the metric system, the micron(one millionth of a meter) is used. 1 mil = 25.4 microns. For optimal adhesion, the applied coating should completely fill the valleys and cover the peaks.

What is bead blasting used for?

Bead blasting is the process of removing surface deposits by applying fine glass beads at a high pressure without damaging the surface. It is used to clean calcium deposits from pool tiles or any other surfaces, remove embedded fungus, and brighten grout color. It is also used in auto body work to remove paint.

What are beads?

A bead is a small, decorative object that is formed in a variety of shapes and sizes of a material such as stone, bone, shell, glass, plastic, wood or pearl and with a small hole for threading or stringing. Beadwork is the art or craft of making things with beads.

What size is 80 grit?

Grit Size Mesh USS Inches (Avg)
#80 70 0.0065
#90 80 0.0057
#100 100 0.0048
#120 120 0.0040

What is #10 glass bead?

Extra Small Diameter Glass Bead Blast Media, #10, 100-170 Mesh Grit, 149-88 Micron Size. 3.6 kg | 8 lbs. Recommended for applications where you want to remove debris without damaging the item’s surface. Glass beads are designed to peen surfaces at low pressure.

What size do glass beads come in?

The most common ​aught sizes you will find at bead shops and online are 15/0 (the smallest), followed by 11/0, 10/0, 8/0, and 6/0. Size 6 is the largest seed bead and is often called an ‘E’ bead.

What is mesh and grit?

Mesh is a count of the number of evenly spaced openings in one square inch of a screen (i.e., screen size). Mesh is basically a specific size or dimension (see Mesh and Micron). Grit is generally defined as an angular media used to abrade or cut a work piece. Grit is a specified range of particles for a given product.

What grit is 60 micron?

Grit, Mesh, and Micron Conversion Chart

Grit (American Standard) Mesh Micron
325 40-50 45
285 50-60 55
240 60-80 70
225 80-100 90

What is bead blast texture?

Bead blasting is a flexible, multi-purpose surface finish that involves shooting high-pressure glass or steel beads at a CNC machined component. A bead blast finish can clean your part’s surface and improve the overall appearance, creating a uniform surface with a dull, satin, or rough texture.

What size blast media do I need for glass bead blasting?

Common mesh sizes for glass bead blasting include 50-70, 60 -80, 70-100, 120 – 200. The fastest cleaning glass bead is typically 60-100 mesh. The right size blast media will ultimately depend on your individual application.

What is a bead blasting finish?

In this process, a bead blaster shoots bead-shaped media from a high-pressured tool towards the material’s surface. A bead blast finish aims to leave a smooth, shiny, and cleaner surface. You find manufacturers using bead blasting for materials like metals, plastic, glass, and rubber to create an excellent surface finish.

What factors affect glass bead blasting usage and consumption?

For all sizes of glass beads: bead size, angle of the blast nozzle, shape of the workpiece, distance from the workpiece, air pressure all dramatically affect the ultimate surface preparation and media consumption. Additionally, direct vs. siphon feed bead blasting equipment also affect how glass beads usage and consumption.

What is the maximum blasting pressure for a single bead?

The larger the bead size the lower the maximum impact velocity, a good rule of thumb is 80 psi maximum blasting pressure for siphon and 40 psi for direct pressure using a pressure pot assembly.
