Manual sand blasting machine processing is different from abrasive cloth and grinding stone friction processing. When the processed abrasive particles fly directly to the surface of the object to be processed, as long as the particles can fly to a certain degree, the processing can be carried out. Because it is not friction processing, although it can improve the surface roughness, it has no smooth and specular effect Easily overlooked.

1. Box: the box is one of the most important parts of sandblasting machine, so the box is named thinking, that is, box. The size of the box depends on the size of the product. For example: if your workpiece is 400 long, 200 wide and 300 high, the box you choose should be at least 600 in length, 400 in width and 550 in height. Of course, there is no such type of machine in the market. Most box type sandblasting machines of most manufacturers have several standard models, which can be selected. If it is a larger size, such as more than 1 meter is generally non-standard model, need to be customized, then you choose the standard box as far as possible, because the price is much lower than the non-standard price.

2. Dust removal fan: some of the box type sandblasting machines are equipped with separate dust remover, while others are not. However, no matter with or without dust remover, there must be a dust removal fan. If there is no dust remover, it can not be seen in the box and can not work. There are two ways to put the dust removal fan: the first is directly placed behind the box, with a hole in the back of the box; the second is placed on the top of the cyclone separator, which is the cylinder separating sand and dust.

3. Spray gun: the most important part of sandblasting machine. It can be said that there is no sandblasting machine without spray gun. Most of the box sandblasting machines use siphon (negative pressure) spray guns: for example, universal spray gun, KL spray gun and KL (Carle type) spray gun switch on the spray gun can save a solenoid valve, but it is rarely used in the market and has little use. The components of the spray gun include sand core, air core and nozzle. The most important and expensive one is the nozzle.

4. Solenoid valve: the solenoid valve of box type Shenzhen sandblasting machine generally adopts the solenoid valve with interface of 4 points. The main function of the solenoid valve is to switch on and off the gas.

5. Some manufacturers did not directly use the pressure regulating filter, but divided the pressure regulating filter into pressure regulating valve and filter with the same effect.
