Tumbler Sandblasting Machine

This machine is powered by a grinding fluid pump and compressed air, using grinding fluid as the medium. It achieves surface cleaning and polishing by rapidly jetting the grinding fluid onto the workpiece surface through a spray gun. The machine can perform the following tasks.

1) Clean the oxidation scale, residual salt, and slag from heat-treated parts, welded parts, castings, forgings, etc., achieving a cleaning quality up to Sa3 level.

2) Suitable for cleaning burrs, surface residues, etc. from machined parts.

3) Modify the surface roughness Ra value of the workpiece.

4) Suitable for pre-treatment processing before coating or plating on workpieces, which can achieve an active surface and enhance the adhesion of the coating or plating layer.

5) Suitable for polishing high-precision and complex-shaped parts.

6) Suitable for improving the physical and mechanical properties of workpiece surfaces, such as altering the state of surface stress, enhancing the lubrication conditions of mating pairs, and reducing noise during the movement of mating pairs.

7) Suitable for refurbishing old machinery.

1.2 Applicable Working Range for the Unit

1) Suitable for liquid shot peening processing.

2) Single pieces and small batch processing for small and medium-sized components.

1.3 Features

1) Significantly reduced dust pollution to the environment and hazards to workers' health.

2) Utilize fine sand materials for surface treatment of precision workpieces.

3) No additional ventilation and dust removal equipment or a separate shot blasting room is required. It can be installed directly online, saving space and facilitating workpiece turnover.

4) Flexible working methods, variable process parameters, capable of catering to the polishing requirements of parts made from different materials and with varying precision levels.

5) The surface quality after processing is high, and under reasonable selection of process parameters, the roughness value is generally reduced by one level after spraying compared to before spraying.

6) Shot-peened parts exhibit a hardened surface, enhancing wear resistance and fatigue strength.

7) The abrasive is recycled during the process, with low consumption.

8) Key components have a long service life and are easy to maintain.
