BDTA shot peening machine
Our BDTA shot peening machine is the endurance runner among shot peening machines and has been delighting its users for decades.
Particularly in the automotive industry, time, professionalism, quantity and quality are of the essence when it comes to the surface treatment of parts.
The BDTA rotary transfer machine can be loaded manually and/or via robot technology and is perfectly suited for large series of shafts, gears and other forged parts.
Furthermore, it has been equipped with very precise flow measuring systems for the abrasive, which makes it possible to determine exactly how much abrasive is to be applied to each workpiece, and the controlled blast wheels can also guarantee a constant ejection speed. The system thus achieves a high degree of reproducibility during processing and can ensure consistent processing quality.
The blasting machine is designed for three-shift operation, and the installation materials used ensure a corresponding service life and the associated ease of maintenance.
Special features of this machine
The system is equipped with 4 blast wheels and is capable of processing around 11,000 shafts or 33,000 gears stacked three high per day. With a throughput of 200 - 250 kg of abrasive per minute and blast wheel, the system operates at average blast speeds of 81 m/sec.
In an emergency, the machine can even be operated with three blast wheels while maintaining the same quality. However, two are the minimum with which the machine can be operated. Various programs are stored in the control system. The customer then only has to "tell" the control system which parts are to be blasted, how many blast wheels are to operate, and at which blast volume and ejection speed. From this data, the control system always calculates the optimum mode of operation for the system and automatically adjusts all parameters and components accordingly. This ensures that each of the blasting machines always delivers consistently optimum results.
Quickly changing the standardized images ensures that only the beam parameters and satellite images need to be changed for the next part generation.
The satellite rotary table blasting machines work with a blast width of 120 mm, so the parts always remain in the hot spot area. V+S realizes this blast width by a special throwing blade design and the special arrangement of the blast wheels, so that even gears stacked three high can be processed optimally with consistently high quality.
The principle of simplicity
V+S follows the principle of simplicity in the development of all systems. What should be understood by this? In order to be maintenance-friendly, the operators and the service staff must understand the equipment, i.e. they must be able to understand how it works. Look at the main wear parts of a blast machine, for example, the blast wheel: If they fail, the entire line will break down. V+S has therefore developed a concept that allows the blast wheels to be completely replaced in a very short time. This means that with this design, a service technician needs no more than 20 minutes for complete removal. The quick-change technology allows all connections to be undone easily and quickly. The entire control and drive electrics are plugged into the system. This means that the complete blast wheel can be completely detached from the system and overhauled in the workshop. After the overhaul, it is available again for the next application. The principle of simplicity naturally also applies to the components within the machine. They are designed in such a way that they do not require any complex mechanical fastenings as far as possible and can also be replaced quickly.
