Table shot blasting machine is a specialized piece of industrial equipment designed to clean, strengthen, or prepare surfaces of metal or other materials by using abrasive blasting techniques. It is commonly used in industries such as automotive, aerospace, foundries, and metal fabrication.
Table Shot Blasting Machine Key Features and Components
1.Rotating Table(s):
The machine has one or more rotating tables (or turntables) on which the workpieces are placed. As the table rotates, the workpieces are exposed evenly to the blasting process, ensuring uniform cleaning or surface treatment.
2.Blasting Chamber:
This is a fully enclosed space where the blasting process takes place. The chamber is designed to contain the abrasive material and ensure safety during operation.
3.Blasting System:
The blasting system typically includes a high-pressure system that propels abrasive material (such as steel shots, grit, or other media) onto the surface of the workpieces. This is done using either:
Turbine Blasting (Centrifugal Wheel): Where a high-speed turbine throws the abrasive media.
Compressed Air Blasting: For more precise applications.
4.Abrasive Recovery System:
After blasting, the abrasive material is collected, cleaned, and recycled for further use. This system typically includes a separator to remove dust and debris from the reusable abrasive.
5.Dust Collector:
To maintain a clean working environment, the machine has a dust collection system that captures fine dust generated during the blasting process.
Table Shot Blasting Machine Application
Cleaning: Removal of rust, scale, paint, or contaminants from metal surfaces.
Surface Preparation: Preparing surfaces for painting, coating, or bonding by creating a rough texture for better adhesion.
Deburring: Removing sharp edges or burrs from machined parts.
Shot Peening: Enhancing the fatigue resistance of metal parts by introducing compressive stress.
How Table Shot Blasting Machine Works
The applications of Rotary table blast machines are mainly for targeted blast cleaning of single/multiple workpieces producing repeatable cleaning results. Placed workpieces on the slowly rotating table, the workpieces are exposed to blast stream from the turbine(s) located on the wall & ceiling of the machine housing.
The shot blast process can occur in single batch mode or indexing with multiple batches placed on the rotary table. Depending on the processing mode, the table is open over 360 degrees or divided into different segments. The layouts of the blast wheels on the table-type blasting machine are mainly according to the features of the parts.
Conclusion
Table Blast shot blasting machine models are the ideal choice for blast-cleaning automotive parts and engine components, petroleum valves and compressors, castings, fabrications and weldments, and numerous other items that are not suitable for tumbling due to size and shape. With Table-Blast shot blast machines, parts to be cleaned are rotated on the table, fully exposing the parts or castings to the abrasive blast media. Table diameters for these shot blast machines range from 36″ to 96″ with workload capacities from 300 to 8,000 pounds. All tables are covered with abrasive resistant liners for superior wear.
