Machine solutions for perfect surfaces
Vibratory finishing is a process inspired by nature for processing different materials such as metals, plastics and ceramics. Special mass finishing systems are used for this purpose. In these systems, the workpieces are placed together with abrasives, water and additives in a container that is set in motion by rotation, vibration or centrifugal force. This relative movement leads to abrasion, which smoothes the surface of the workpieces. The resulting abrasion material is absorbed into the process water, which must be reprocessed after mass finishing.

deburring
Deburring removes unwanted residues such as burrs, chips or fraying from workpiece edges and surfaces. These often occur during machining processes such as milling, punching or casting. Removing burrs not only improves the appearance of the workpiece, but is also crucial for its functionality, safety and further processing – for example, during assembly or coating.
edge rounding
Edge rounding – also known as edge breaking – is an important part of the deburring process. It involves deliberately rounding off sharp edges and corners on workpieces, usually made of metal. Rounded edges not only ensure safe handling, but also improve the adhesion of coatings and reduce the risk of corrosion. In addition, edge rounding enhances the appearance of the workpiece and facilitates further processing.
polishing
The aim of polishing is to remove unevenness, scratches, grooves and small cracks in order to achieve a smooth and shiny surface. Polishing not only improves the appearance, but also offers functional advantages such as reduced friction, improved cleaning properties and greater resistance to external influences.
Cleaning/descaling
Cleaning or descaling in the vibratory grinding process serves to remove contaminants such as oils, greases, oxide layers or other dirt from the surface of the workpieces. This step is crucial to ensure a clean and functional surface – whether for direct further processing, coating or immediate use of the parts.
The duration of a vibratory finishing process depends on various factors and cannot be answered in general terms. The decisive factors are the workpiece material, the process media used, the vibratory finishing machine and the desired surface quality. When comparing processing times, processing in rotary machines takes the longest, followed by processing in vibratory machines. Centrifugal processing is the most efficient and can be up to 10 times faster than processing in vibratory machines.
The liquid used in vibratory grinding is called a compound. Compounds are highly effective, biodegradable mixtures of active ingredients designed to optimise vibratory grinding processes. They improve grinding performance, clean, degrease and protect against corrosion. Available in liquid, solid or powder form, they can be flexibly combined with additives such as defoamers or biocides, ensuring stable machining processes and consistently high quality.
There is no difference between vibratory grinding and trowalising. These are two different terms for the same type of surface treatment. It is a process inspired by nature that is suitable for treating surfaces made of metals, plastics and ceramics, for example.
Barrel finishing is a mechanical process for surface treatment. Workpieces are placed in a container together with abrasive media, water and compound and set in motion by vibration, centrifugal force or rotation. The abrasive media and workpieces slide past each other, causing abrasion on the workpieces and smoothing their surface.

Inspection technology for maximum precision
The material handling is realized by our in-house machine construction in coordination with the requirements of the inspection technology.
Our proprietary software solution makes it possible to solve the inspection task in a customer-specific manner and includes the option of defect classification and statistical evaluation.
EMS sensors
This measuring principle for checking the electromagnetic signature is used worldwide in vending machines in which coins are used for payment. Inductive testing of the coin or coin blank provides information about the material composition and/or coating of the coin/blank. The measured values of the individual object are compared with a material database and assessed as good or bad depending on the deviation from the references or the deviation defined as acceptable.
Eddy current measurement
Eddy current measurement is a non-destructive method for testing metallic surfaces. With the help of high-frequency electromagnetic interactions, different material hardnesses can be detected and analyzed both manually and automatically. This method plays a decisive role in quality assurance, as it measures the mechanical resistance of a material against the penetration of another body.
2D camera technology for edge inspection
For geometric reasons, 2D and 3D camera technology only captures the top and bottom of an object, but not the edges. A special 2D camera in combination with a ring light and a catadioptric lens is used to inspect the edge surfaces.
The following features can be checked using 2D camera technology for edge inspection:
3D camera technology
3D image capture picks up where 2D camera technology reaches its limits, particularly with regard to the depth of field of the images and the ability to recognize differences in height. To create a height profile, the component is illuminated with a line laser. The laser beam is reflected and captured by a camera. The illumination of the line laser generates many sectional images. This partial information of the component is put together by the software to form an overall object.
The following features can be checked using 3D camera technology:
2D camera technology
2D image capture is based on the principle of the human eye – light falls on an object, is reflected and captured by the eye. In our systems, artificial lighting is used to generate light beams that are reflected by the object and captured by the camera. The choice of suitable lighting and camera depends on the application.
The following features can be checked using 2D camera technology:
Decision
The components are classified based on the set inspection parameters. The data can be stored and analyzed via an SQL database or transmitted to a higher-level system.
Image analysis
The image analysis is performed by algorithms that process the data generated by the image acquisition. These algorithms are integrated into the operating software, which is used to control the system and define and save the inspection criteria.
Image acquisition
Image acquisition includes the selection of lighting and camera technology. The type and sensitivity of the components are determined according to the previously defined test characteristics and tolerances.
Handling
The variety of components and the desired degree of automation make component handling crucial. Transport and precise positioning under the inspection tool are crucial for optimum inspection results.
Inspection
The same requirements apply for an optical inspection as for the human eye. It is important to describe the component, define the characteristics to be tested and specify the tolerances.
