How does the shot blasting machine handle steel abrasives with oil?

Oil-coated steel abrasives must be air-dried when they are treated with a shot blasting machine, otherwise the treatment effect will be directly affected.

Workpiece coating, pre-bonding treatment
Shot blasting can remove all dirt like scales on the surface of the workpiece, and establish a very important basic pattern on the surface of the workpiece (the so-called rough surface). By changing the abrasives with different sizes, different degrees of roughness are achieved, and the bonding force among the workpiece, the coating, and the plating material are greatly improved, or make the bonding part stronger and of better quality.

Rough surface cleaning and cleaning workpiece after heat treatment
The shot blasting can clean all the dirt on the surface of the workpiece after casting and forging, such as oxide scale and oil stain, and polish the surface of the workpiece to improve its smoothness. The workpiece is exposed to a uniform metallic color, which makes the appearance of the workpiece more beautiful and achieves the effect of beautifying the decoration.

Cleaning burr of the machining parts and surface beautification
Shot blasting can clean the surface of the workpiece with small burrs, and make the surface of the workpiece flatter, eliminating the damage of burrs and improving the grade of the workpiece. And the shot blasting can make a small rounded corner at the intersection of the workpiece surface, making the workpiece look more beautiful and more precise.

Improve the mechanical properties of the parts.
After the sandblasting, the mechanical parts can produce uniform and fine concave and convex surfaces (base pattern) on the parts, so that the lubricating oil can be stored, and the lubrication conditions can be improved and the noise can be reduced, which improves the service life of the machine.

Polishing
For workpieces that use for some special purpose, sand blasting can achieve different reflection or matt, such as stainless steel workpieces, matt surface of wooden furniture, decorative pattern on frosted glass surfaces, and texturing on the surface of fabrics.

How many Categories of Shot Blasting Machines?


There are five categories of China shot blasting machines: road surface shot blasting machines, tumble shot blasting machines, hook type shot blasting machines, table shot blasting machines, internal steel tube shot blasting machines.
Here's a detailed introduction of the characteristics of various kinds of shot blasting machines.
1. Road surface shot blasting machines
Shot blasting machines for road surface are mainly used to solve the defects of the concrete surface treatment. It can remove laitance and impurities of concrete surfaces at one time, and can have the coarsen treatment of the concrete surface, which brings the uniform roughness of surface. This greatly improves the adhesive strength of waterproof layers and concrete base layers, so that the waterproof layer and the bridge deck can be combined better and the crack of the concrete can be fully exposed at the same time, which is a prevention solution. Automatic reverse blowing dust collectors can clean each filter element through air blew back by the compressor at regular intervals. Then, it will be cleaned through the airflow of the assorted cleaner inside the machine. The abrasive material and the cleaned impurity will be recycled respectively, and the abrasive material can be reused. Each shot blasting machine is equipped with a dust collector so that the construction can be dust-free and pollution-free, which can both improve efficiency and protect the environment.
Advantages:
Shot blasting machines for road surface can be used in the surface treatment of the waterproof base of concrete bridges, the surface coarsen treatment of the pavement overlay, cleaning of the sign line of road, bridge and the steel box girder, improvements of anti-slide performance. Also, it can greatly improve the roughness and texture depth. The uniform roughness will not destroy the original surface structure and integrity. The entire process of construction is dust-free and impurities are completely recycled.
2. Tumble shot blasting machines
Tumble shot blasting machines are is applied for surface cleaning and strengthening of large and medium sized production parts. When the parts to be cleaned is less than 200kg, this machine can be used alone or used as a supporting facility.

Advantages:
With the advantages of large shot blasting, high cleaning efficiency, large space, compact structures and no special requirements on the shape and structure of the cleaning piece, a hook shot blasting machine can serve several purposes. It is applied for sand cleaning, rust removal, scale removal and surface reinforcement of the castings and forgings less than 15kg of various industries. This machine is equipped with a special set of dust device, so the place of installation is free from the ventilation pipe workshop and it has good sanitary conditions.
4. Table shot blasting machines
The table shot blasting machine is mainly used for volume surface cleaning of small and medium sized workpieces. It is suitable for the engine connecting rod, gear, diaphragm spring , etc. It is widely used in the casting and automobile manufacturing industries. It has several characteristics of high production efficiency, good sealing performance, compact structure, convenient loading and unloading parts, high technical content, etc.
Advantages:
The table shot blasting machine is mainly used for the removal of surfaces' sand, rust, oxide skin, dirt, etc., which can restore the surface color of the metal workpiece, eliminate the internal stress, improve the anti-fatigue performance, increase the film adhesion, and ultimately achieve the goal of improving the surface and internal quality.
5. Internal and External steel tube shot blasting machines
An internal and external steel tube shot blasting machine is a new type of net wall shot blast cleaning machine combined with the shot blasting technology to clean the inner wall of the cylinder.
It uses compressed air as its power and utilizes the kinetic energy of accelerating projectile to shoot the cylinder wall. When the cylinder located in the gun room, the gun will automatically insert into the respective bottle and the spray gun will move up and down in the cavity. Then it will complete the full range of cleaning. Inside and outside wall shot blasting machine is the selected type of the cylinder industry.
Advantages:

What Kind of Steel Shot Is Used In Shot Blasting Machine?


Steel Shot Blasting
Usually, the hardness of steel shot can be improved to HRC40 ~ 62. It can be used in processing hard metal. It is more widely applied in shot blasting machine because of its excellent toughness and long service life.

Cast Iron Shot Blasting
The hardness of cast iron shot is HRC58-70. Cast iron shot is too brittle to be broken easily, so the service life is short. It is mainly applied in those processing of high shot peening strength requirements.

Glass Bead Peening
The hardness of glass bead is less than the previous two steel shot, which is mainly used in processing stainless steel, titanium, aluminum, magnesium, and other situation excluding iron pollution. Also, glass bead can be used in secondary surface treatment after steel shot blasting in the purpose of removing the iron pollution and reducing the roughness of workpiece surface. http://www.jxabrasives.com/
