Automatic blast cleaning machines work tirelessly and maintain regular quality. Automation refers to moving the blasting nozzle and piece in a controlled manner, for example. The machine may also include automatic piece detection, blasting pressure and shot amount adjustment, and other automatic functions. The size of the piece can be measured on-line, and the nozzle can then be guided according to this measurement.
Below, you can find some examples of fully automatic blast cleaning machines.
FB 1100 with satellite table
The FB 1100-SP is an automatic cabinet equipped with a satellite table. It can be operated by means of ejectors, or with compressed air. Depending on the size of the blasted pieces, there can be 10–20 satellite tables.
The blasting medium can be steel shot, glass beads, aluminium oxide, etc.
The pieces are loaded on the satellite tables, and the blasting is started. The machine will automatically blast clean all the pieces according to the selected logic programme.
The input and extraction of pieces can be automated using a robot, for example.
FB 2100-2D with two automatic nozzles
The FN 2100-2D is equipped with two automatic blasting nozzles. The movements of the nozzles can be easily programmed in order to clean pieces with complex shapes.
The movement of the piece inside the chamber can also be programmed.
FBD- 3400-3D Fully automatic blasting equipment for train wheel sets
The FBD 3400-3D is designed for the automatic blasting of wheel sets for train cars.
The machine has a single blast nozzle, and its movements are easy to programme. The device is flexible to use, and it can be used to blast only the axle or only the wheels, for example. The blast cleaning results meet the requirements of EU directives and VPI standards.
Noise level during blasting can be below 80 dB(A).
Automatic blast cleaning for pieces on overhead conveyor
Pieces that move on an overhead conveyor can be cleaned effectively and fully automatically.
The conveyor may have pieces of different sizes in random order. The height of the piece and the position of its base are measured as the piece enters the blasting chamber.
In the blasting chamber, the piece is blasted in accordance with the height measurement. Once blast cleaning is complete, compressed air is used to remove dust from the surface of the piece.
FB 2000 – 2D
This cabinet is used to blast axially symmetrical pieces, such as tubes, rolls, axles, etc.
The moving gear for the blasting nozzle is located on the roof of the chamber. The movement of the nozzle and the rotation of the piece are controlled by programmable logic. The automatic blast cleaning keeps the cleanliness and roughness of the blasted surface at a similar level, day after day and week after week.
The machine is dust-free and has a low noise level.
The FB 8000 is an 8-metre blast cleaning cabinet.It is flexible and versatile.
The cabinet is designed for the automatic blast cleaning of pipes, rolls, and hydraulic cylinders, for example. The blasting generates no dust, as it takes place inside an enclosed chamber.
The cabinet also has a turntable for blasting smaller pieces and contains provisions for manual blast cleaning.
