General Introduction of SS-10 wet blast machine

1.1 Application

Driven by media pump and compressed air, this machine is a new type of equipment specially designed for wet blast process utilized in finish.

The machine can clear castings and forgings, weldments, heat-treated parts, punched and machined workpieces and can knock off the rough surface, oxide crust, remaining salt, burs, and etc. It can be applied to do pre-treatment for coating and plating, high precision and high smoothness finish process on complicated-shaped components that other methods cannot accomplish. It’s also very good at renovating used machined parts.

1.2 Features

1. Dust pollution is effectively under control during process.
2. No need of any extra ventilator and dust remover, this machine can be directly installed on a product line so as to save working area and facilitate parts flowing.
3. With the variety of flexible operating methods and technological parameters, this machine is fit for requirements of finish processing for parts made of different materials or in various precisions.
4. The blasting process can improve machined parts surface quality and reinforce parts skin so as to increase wear-resistance and fatigue strength.
5. Media consumption is limited.
6. Major components of the machine are long-lived and are easy to be maintained
7. Operator works in a low labor intensity with a high production efficiency.

1.3 Buildup

The machine composed by main unit, outer guide track, media collector and separator as shown in SS-10 Wet Blast Machine View, can be used in basic operation of the wet blast process and accessorial operations later.
