Rotary systems
The processing of surfaces by rotation is one of the oldest and simplest processes in mass finishing. The simple operation and robust technology make rotary systems an economical choice – especially for small to medium quantities.
Work bowl & functionality
In barrel finishing, workpieces are placed in a rotating container together with abrasive media and compound. The material is removed by the resulting relative movement between the workpiece and the abrasive media. The process is versatile and particularly suitable for homogeneous machining.
Barrel finisher RTS
Our RTS system combines the basic principles of mass finishing with modern technology. The integrated separating device has a collection container for grinding media that can be conveniently emptied at the front. Two drums can be operated in parallel – ideal for processing different workpieces in the same work cycle.
Surface grinding bells SC/PC
The SC and PC mass finishing bells differ mainly in the shape of their work bowls, which are available in several sizes. Both variants have a closed lid. They can optionally be fitted with a rinsing or sieve cover – ideal for multi-stage machining processes or sensitive workpieces.

Frequently asked questions about our rotary systems
How do rotary machines differ from vibratory or centrifugal machines in terms of processing?
Rotary drums and vibratory finishing bells are characterised by gentle processing, making them ideal for processing sensitive components. However, the processing is time-consuming.
Roundtub vibrators operate at approximately twice the speed of rotary systems and offer a good balance between processing quality and process speed. Centrifugal systems are the fastest in comparison – they achieve up to 20 times higher processing speeds than vibratory systems. They are particularly suitable for high volumes and short cycle times.
For which users are roller drums suitable?
Roller drums are particularly suitable for users who work with small batches and want to rely on a cost-effective process. Due to the low investment costs, they represent an economical solution for small production quantities. Another advantage is that when several small drums are used, different batches can be processed in parallel. This makes roller drums ideal for flexible manufacturing processes in which different materials or processing stages are to be handled simultaneously.
What sizes and capacities are available for drums?
Our RTS roller drum consists of a base frame that can be equipped with drums of different sizes. Depending on the size of the drums, it is also possible to process two batches in different drums at the same time. Drums with a volume of 9 and 15 litres can be used in parallel. With a drum volume of 35 or 50 litres, only one drum can be used.
What is the difference between SC and PC surface finishing bells?
The SC and PC surface finishing bells differ mainly in the shape of their working containers and thus in their possible applications.
SC bell jar – ideal for large workpieces
The conical shape of the SC’s working chamber provides a generous opening that makes emptying easier. This design is particularly suitable for larger workpieces and ensures an efficient workflow.
PC bell – ideal for smaller workpieces
The double conical shape of the PC bell enables particularly good circulation and mixing of the workpieces. This makes it ideal for smaller parts and uniform processing.
What is the function of the different covers on the SC and PC surface finishing bells?
Three different cover variants are available for the SC and PC surface finishing bells, each of which fulfils different functions:
Closed lid (standard)
Made of painted steel, the lid protects the bulk material and serves as effective splash protection during wet processing.
Rinsing cover (optional)
The rinsing cover is made of perforated stainless steel and is equipped with a rotatable hose connection. It enables targeted rinsing, ensures clean processing results and facilitates the separation of workpieces and abrasives – especially in multi-stage processes.
Screen cover (optional)
The screen cover – made of perforated stainless steel sheet or pressed mesh – also serves to separate workpieces and abrasive media. It is mainly used for dry processing, e.g. with walnut shells, and supports efficient workflows.
