Pressure sand blasting machine is a new type of surface processing equipment, widely used in machinery, locks, electronic clocks, glasses, hardware tools, molds, glass, ceramics, crafts, medical equipment and other industries. It can remove casting blanks, forging, stamping, Welding, heat treatment and machining of oxide scale, residue and burr, three-dimensional glass carving, spray painting and other processes. On the surface of decorative objects such as watches and clocks, it has the effect of imitating alloy. Is currently the ideal surface processing and processing equipment.
How to choose a pressure blasting machine:
1. Depending on the size of the workpiece, choose box blasting machine, mobile blasting machine, and automatic blasting machine;
2. Depending on the shape of the product, choose the specifications of the sand blasting machine. Generally, those below one meter have fixed specifications. Particularly large ones need to be customized or open.
3. The degree of requirements for the product surface depends on whether it is dry spray or wet spray. If it is dry spray, there are many choices of abrasives, and wet spray is generally glass sand.
4. Some accessories of the sand blasting machine should be familiar. The sand blasting gun and the sand blasting gloves are often changed, because the sand blast is actually very worn.
Impact of Abrasive Type on Surface Results Abrasives are divided into spherical and rhombic types according to the state of the particles. Emery abrasives (white steel jade and brown corundum) commonly used for sandblasting are diamond-shaped abrasives. Glass beads are spherical abrasives. After the three values of P, H, and θ are set, the surface obtained by sandblasting with spherical abrasives is smoother, and the surface obtained with rhombic abrasives is relatively rough, and the same abrasive is divided into thicknesses. The abrasives are divided according to the number of screens in China The thickness is generally called the number. The higher the number, the smaller the particle size. After the P, H, and θ values are set, the higher the number of the same abrasive blast, the smoother the surface result.
