Rotary Table Blast Machine

Rotary Table Blast Machine , also known as Table Type Shot Blasting Machines, are specialized equipment designed for cleaning, deburring, and surface preparation of various components. These machines utilize a rotating table to expose parts uniformly to abrasive blast streams, ensuring consistent and efficient treatment.

Design and Operation

The core feature of these machines is a rotating table that holds the workpieces. As the table rotates, the components are exposed to the blast stream, effectively removing contaminants such as rust, scale, and old coatings. This design is particularly advantageous for parts that are too large, heavy, or delicate for tumbling in traditional blast machines.

Key Features:

• Rotary Table: The rotating table ensures uniform exposure of all surfaces of the workpieces to the abrasive blast stream. Table diameters typically range from 36 inches to 96 inches, with load capacities from 300 to 8,000 pounds.
• Blast Wheels: Strategically positioned blast wheels direct abrasive media onto the components, effectively removing contaminants. Some models feature oscillating blast wheels to allow more thorough blast pattern coverage.
• Abrasive Resistant Liners: The tables are covered with abrasive-resistant liners to withstand the wear from continuous blasting operations.
• Dust Collection System: Integrated dust collection systems help in meeting environmental regulations by minimizing airborne pollutants.

Applications

Rotary table blast machines are versatile and find applications in various industries:

• Automotive: Cleaning engine components, gears, and other critical parts to ensure optimal performance and longevity.
• Aerospace: Preparing turbine blades, landing gear components, and other parts for coating or inspection.
• Heavy Equipment Manufacturing: Surface preparation of large castings, forgings, and welded structures to enhance paint adhesion and durability.

Advantages

• Uniform Cleaning: The rotating table ensures all surfaces of the component are exposed to the blast stream, resulting in consistent and thorough cleaning.
• Gentle Handling: Suitable for delicate or intricate parts that cannot withstand the tumbling action of other blasting machines.
• Efficiency: The design allows for simultaneous loading/unloading and blasting, reducing downtime and increasing productivity.

Considerations

When selecting a rotary table blast machine, consider the following:

• Table Size and Load Capacity: Ensure the machine can accommodate the dimensions and weight of your components.
• Number of Blast Wheels: Machines may come with single or multiple blast wheels, affecting the efficiency and uniformity of the blasting process.
• Abrasive Media Compatibility: Verify that the machine is compatible with the type of abrasive media required for your specific application.

Conclusion

Rotary table blast machines are essential tools for industries requiring meticulous surface preparation of large or delicate components. Their design ensures uniform cleaning while handling parts gently, making them an excellent choice for applications where component integrity is critical.
