Vibratory Finishing Media (Pyramid Tetrahedron shape)
We can also make other size vibratory finishing media that not show in the table, so please contact us to get detail information
1. Why Pyramid Tetrahedron Shape Media?
1.1 Pyramid Tetrahedron shape media prevent lodging
Pyramid Tetrahedron media have wide applications. Because it allows partially to enter holes of various diameters without lodging problems. An example is gun components as it have hole and slots with different size and shape. A certain media need to select to prevent lodge in problem. Besides, parts and media should have significant difference in size. So they can easy to make the separation.
1.2 Pyramid Tetrahedron shape media offer to move contact area
The photo above shows two different shape of media – one is cone and another is pyramid shape. Comparatively, if you want to achieve most planar contact between parts and media, then pyramid shape is a better idea. The pyramid shape have 5 flat surfaces. And it includes 1 square surface and 4 triangle surfaces. However, Cone shape only have 1 planar surface, which make it less possibility to make the parts to media contact in same period of time.
Whenever parts is contact with pyramid shape media, a planar contact can be made regardless shape and direction of parts.
1.3 This mixture of pyramid and tetrahedron shape media reduce cost
Pyramid and tetrahedron shape media is usually manufactured with the same cutting process. Besides, the mixture of two types of media with 1:1 combination also called T/P media. Because TP shape ceramic media can easy to achieve automation, the price of T/P media is much cheaper than pyramid shape or tetrahedron shape.
2. General Properties
2.1 Features of Vibratory Finishing Media
- Engineering use ceramic media mostly metal components deburring and descaling
- Vibratory Finishing media have varieties of different size and shape
- Vibratory Finishing media have wide application rage. It suitable for vibratory finishing machinery and most other surface finishing machine.
2.2 Ceramic media Composition
Manufacturers make ceramic media with mixture of several mineral materials. These materials including: abrasive grit, clay, feldspar and sand. Later, theses material mixed homogeneously and stirring machine with constant water dosing. After that, a vacuum compressor removes void in the material and make it a solid and rigid material before drying and baking.
First of all, ceramic media are available in a wide range of shapes and sizes. Also, engineer selects right grade of abrasive grit, the proportion of abrasive to binder, and the most suitable binder. All these factors contribute to the ceramic media performance. As a result, the right selection of media meet requirement of certain parts and application.
While abrasive grit cut material from parts, the binder acts as a burnishing surface, and this works against rapid cutting.
