Blasting processing is the one of method to make the effect to surface of work piece. And the purpose are deburring, surface design, add the function and etc. By Air blasting, wet blasting and shot blasting (Impellor).
The special feature of blasting process is deburring, cleaning, strength improvement, polishing and prepare surface for coating, painting or painting removal.
Blasting is the wide useful with complex surface shape of the work piece. And in the condition of materials / shapes / sizes / air pressure / impellor power adjusting also make more blasting’s feature.
3 ideas of blasting processing (Cutting / Removing /Strength improving)
3 Ideas of blasting processing
1. Cutting (Cutting the work from each other)
2. Removing (Remove the dirt, scratch, scrape, coating)
3. Strength improving (Change the surface property)
Let’s go to the see more details of them below.
“Cutting” processing is depending on the burr or if you need more affection of grinding roughness, you should be choosing the big size. In the condition of short time processing is good to use the hard media. Let’s see some example case below・The general treatment is grinding and make the surface like satin.
Removing somethings from surface (dirt, something uncleanness, greasing oil, oxide film, burr) Since it is necessary to remove the product without damaging it, relatively soft abrasives such as copper and nylon are often used. It has various uses such as
This is a process that changes only the properties of the surface by the collision energy of the abrasive without scraping the surface. A spherical abrasive is often used so as not to scrape the surface.
・"Peening" to forge the surface and increase durability (residual stress application, work hardening)
・"Forming" aiming at forming a deformed curved surface by applying residual stress
