TV - Trough vibrators

The tub vibratory finishing machine, which has a size similar to a washing machine, with a fill volume of 70 l is our standard machine and is ideal for prototypes and small series. A noise protection cover reduces the noise and makes it possible to work in a workshop.

The right and left-hand circulation as well as speed regulation from 1,500 to 3,000 rpm provide for various processing possibilities. The abrasive material and workpieces are rotated through the generated vibration. The desired processing process is created through the contact of grinding bodies on workpieces. The programmable timer rounds off the autonomous work process.

The machine has a modular construction and can be expanded with an optional paper filter and separator. Both are controlled centrally through the control panel on the TV 95-SL.

We recommend the PF440 paper filter for simple and comfortable water treatment. The paper filter is filled with 36 L water + compound during commissioning. The process water is pumped in the tub and cleaned through a filter fleece upon return.

The S95 separator simplifies the separation of grinding bodies and workpieces. Sorting sieves are available in many sizes. The grinding bodies are poured back into the tub after separation.

The finishing process:
Barrel finishing does not just mean a procedure for surface processing workpieces, but rather offers a wide range of possibilities for changing and refining surfaces. Optimal processing results are achieved through the right combination of machine as well as chips and compounds. Whether rough grinding or to achieve polished surfaces, Assfalg always offers the optimal process media.

The deburring process and surface treatment can be set according to the customer’s request depending on the shape, quality and dimensions of the ground bodies. The form of the chip must be coordinated to fit the workpiece geometry. All contours should be achieved and processed and deadlocks must be simultaneously avoided. The grinding behaviour is influenced by the shape of the chip as well - round shapes are less aggressive than pointy shapes.

The grinding performance and surface appearance are determined by the quality of the chip. The heavier or larger the chip, the rougher the surface structure and more intense the grinding performance.

The main task of the compound is to keep surfaces from workpieces and chips clean during the handling process. The selection of the compound is carried out depending on the place of use, the material to be processed and desired processing target and the properties of the compound.
