Advantages of Drum-Type Shot Blasting Machines
Drum-type shot blasting machines are mainly suitable for small-sized, non-fragile metal castings, stampings, springs, fasteners, and small forgings for removing oxide scales, rust, burrs, and surface strengthening. Drum-type shot blasting machines complete the cleaning process by rotating the workpieces with drums and using high-speed shot blasting nozzles to throw steel balls onto the workpieces. Compared with other cleaning equipment, drum-type shot blasting machines have the following advantages:
1. Uniform workpiece rotation and comprehensive cleaning:
The drum rotates at a low speed continuously, and the workpiece rotates inside the drum. The steel balls can reach all surfaces of the workpiece, with few dead corners. Small and batch-sized parts can be thoroughly cleaned, including internal, edge, and corner burrs, oxide scales, and surface strengthening. The cleaning consistency is good.
2. Suitable for batch processing of small parts, high efficiency:
The drum-type shot blasting machine can hold a batch of small parts at once and process them automatically without manual placement. It is suitable for screws, springs, small castings, and stamping small parts, significantly reducing labor costs and suitable for continuous production of small batches.
3. High automation level, simple operation:
After loading and closing the drum, set the time and the machine will automatically run until the cleaning is completed and then stop automatically. Novices can operate it with simple training. The labor intensity is much lower than manual sandblasting.
4. Cost-effective, low operating costs:
- The equipment occupies a small area and does not require complex tooling and fixtures;
- The steel balls are recycled and reused, with controllable loss;
- Compared with sandblasting, there is less dust, lower material consumption, and suitable for long-term, large-scale, and small-piece processing.
5. Good surface strengthening effect:
The shot blasting impact can cause compressive stress on the workpiece surface, not only removing rust and burrs, but also improving the fatigue strength of springs, fasteners, and other parts, achieving surface strengthening and extending the service life of the workpiece.
6. Sealed operation, low dust pollution:
The drum-type shot blasting machine has good sealing effect, is equipped with a dust collection system, and separates the steel balls and dust. Dust is collected centrally, improving the workshop environment, meeting environmental protection requirements, and the steel balls will not fly around.
7. Wide applicability to materials:
Cast iron parts, cast steel parts, stampings, springs, aluminum alloy small parts, and heat-treated workpieces can all be used to remove oxide scales, rust, and heat treatment black skin.
