The most comprehensive range of consumables on the global market
At Rösler, we have been developing and producing ceramic finishing media for well over 60 years. What began rather haphazardly after the end of the war with the recycling of broken ceramics and pharmaceutical porcelain is now the largest finishing media portfolio in the world.
Ceramic media is a true all-rounder: it is ideal for aggressive grinding and edge rounding for harder and tough materials as well as deburring softer materials such as aluminum and brass.
Compared with plastic abrasives, ceramic media is cleaner and consumes less water and compound. Because of its higher weight, it also has a higher grinding pressure on the work piece and thus works more effectively (i.e., it has a higher grinding capacity).
But ceramic media can do much more: it is extremely durable, has a good price-performance ratio, and can be produced in the smallest diameters (down to 0.8 mm). Various different sizes and geometries leaves almost nothing to be desired and offer the perfect tool for every requirement.
Our variants of efficiency in ceramics
The ceramic triangle is the true all-rounder among finsihing media and is used as a cost-effective and efficient solution in many different applications. With its angular shape, it ensures a high material removal capacity and even reaches complex workpiece contours.
Triangle - with large radius (F)
Due to its significantly larger radii, the “F” triangle is more mechanically stable and therefore less sensitive to mechanical stress than the standard triangle. It is primarily used in centrifugal disc finishing machines or for processing heavy workpieces and/or components with blind or tapped holes.
Triangle angle cut (S)
Angle cut triangles have a higher cut rate compared to standard triangles. With these grinding media, burrs and sections of workpieces that are difficult to access can also be reached more easily.
Special media shapes are required for processing gear components and parts with difficult-to-reach contours. Often, only tristar and angle cut tristar media can reach the base of the gear tooth on the workpiece. Due to the surface indentation compared to the basic triangle shape, the tristar contoursremain stable over a long period of use.
Tristar angle cut (DZS)
The tristar also achieves a higher removal capacity with an angle cut. In addition, the tristar angle cut reduces the risk of media becoming lodged in parts compared to the normal tristar shape.
Ellipses and angle cut ellipses are primarily smoothing media. Due to their shape, they have good rolling properties and process workpieces gently, leaving a uniform, homogeneous surface.
Ellipse angle cut (ES)
This type of grinding media is an evolution of the straight cut ellipse. This makes it easier to reach complex workpiece contours and therefore avoid “shadows”.
Granulate and balls are suitable for lightly deburring and smoothing or cleaning workpieces, including inside pipes or longer blind holes. Lodging can be almost completely avoided. It should be noted that due to the point contact on the surface, the material removal is extremely low. When brightening, polishing and even matting surfaces, granulate/balls achieve good results.
The cone shape combines high material removal with optimal surface finishing and edge protection for workpieces. The linear surface contact creates a finely structured surface pattern. , The separation of flat workpieces is aided and the risk of finishing media being discharged with the workpieces is reduced.
This extremely agressive media shape (actually a tetrahedron) has four edges, four faces, and 4 points. The almost equilateral surfaces guarantee high shape stability over the entire service life. The usually insignificant loss of geometry minimizes the risk of the grinding media lodging in grooves and holes. This compact shape has ideal separation characteristics and is also ideal for undersized media classification (the automatic separation of media that have become too small).
The quinto shape, also known as tri-cyl, is very versatile and moves easily. It works in a similar way to cylinder-type media. Due to its pointed wedge shape, it is also suitable for narrow radii, holes and slots. This shape combines unique radii and edge finishing with a uniform surface pattern.
Elbow-shaped finishing media, or arrowheads, are often compared to tristar shapes and are used in very similar applications. However, with larger material recesses, the significantly heavier elbow shape is more efficient and mechanically more stable than the lighter, intricate tristar.
Cylinders are well suited to completely removing internal burrs from sections of pipe or drill holes. However, they are also useful for other applications: cylinders are considered the ideal polishing media and their rolling shape makes separation easy, especially with flat workpieces.
Angle cut cylinder (ZS)
This shape of finishing media easily feeds into holes and openings and passes through channels and tough to reach areas with little resistance. During separation, the angle cut cylinder behaves in the same way as the straight-cut version.
MultiShape media are ideal for the high-precision surface finishing of complex workpieces and internal areas. Thanks to their unique shape, they can increase the speed of the media movement in the work bowl by up to ten percent, which helps reduce processing times and increase the material removal rate on the workpiece. The MultiShape grinding finishing media are globally unique. They retain their shape even after a long period of use and are therefore very economical for the customer. The complex geometry of these grinding media greatly reduces the risk of several media becoming lodged in cavities and narrow openings in the workpiece.
