Trust our innovative planetary head system for perfect edge rounding. With the dual rotation of workpiece and head, we achieve uniform rounding on both inner and outer contours. Our brushes always work at the optimal angle on the workpiece. With our patented WEBER solution, the tools of adjacent heads overlap seamlessly to avoid gaps during processing. Our planetary head system is particularly suitable for gentle edge rounding. Thanks to low feed speeds and compact design, the workpieces are also particularly low-wear.

We offer our planetary head system in two variants: one with six tools per head, arranged in two rows, and a compact version with two tools per head in a single row.

For long-term durability, our planetary heads are completely sealed and filled with grease, protecting them from dust and dirt. The automatic workpiece length measurement allows for monitoring of workpiece wear and seamlessly transmits the corresponding data to the system.

The STC bolt grinding bar offers consistent grinding quality, high material throughput rates, and low operating costs thanks to the long service life of the grinding belt. Its functionality is well thought out: the flat grinding belt is lightly tensioned downward, automatically allowing for improved deburring without the formation of secondary burrs. This tension automatically compensates for existing thickness differences, supporting efficient multiple processing – a crucial advantage, especially for small parts. Initially, rough deburring is done by a preceding roller before the bolt grinding bar precisely applies the grinding belt to all corners and edges. This ensures burr-free deburring with maximum tolerance compensation, even for small parts and repeated processing operations.

Mass stamped parts often have sharp edges or burrs on the cut edges that need to be removed for safe handling and assembly. These punching burrs can have a strong burr root, the severity of which can vary depending on the material.

For parts with minimal burr formation and a low need for edge rounding, the use of our planetary head system may be sufficient. However, for heavily pronounced burrs, the combination of multiple systems is often recommended.

The processing of mass stamped parts typically involves the use of emulsion or oil to reduce friction and ensure a uniform surface. These lubricants play a crucial role in prolonging tool life and improving the quality of processed parts.

To further increase efficiency, the grinding system is often equipped with cleaning systems. This allows residues of lubricants and metal chips to be effectively removed, which not only improves the quality of the parts but also extends the life of the machines.

WEBER offers customized solutions for deburring autogenously or plasma-cut parts, whether in single or series production.

Our techniques can be single-stage or multi-stage, depending on the specific requirements and tolerances of the workpieces. To process the workpiece tolerances optimally, we rely on the use of a bolt grinding bar that works precisely to meet even the most demanding tolerances while simultaneously removing sharp edges and irregularities. For parts with higher requirements for edge breaking or rounding, additional cup brushes or round brushes are used to achieve a uniform surface and refine the edges.

Deburring laser-cut parts typically requires at least a two-stage process to achieve the desired results. The first step in this process is roller grinding, which effectively removes splatter from the surface and allows for basic cleaning.

A crucial aspect of deburring is edge processing. Here, our WPS brush system comes into play, which not only rounds off the edges but also removes scale from the cut surface. The system processes all edges uniformly to achieve a homogeneous result.

Depending on requirements and material characteristics, various types of brushes are suitable. For example, cup brushes work more aggressively and allow for stronger edge rounding, while round brushes operate more gently and provide less edge rounding. These can be adjusted to a certain depth according to the requirements.

At WEBER, we rely on innovative technologies such as the patented single-row planetary head system or a double-row arrangement. The generous coverage of the processing areas results in an almost perfectly uniform rounding result that meets the highest standards of quality and precision.

But that's not all – for an appealing surface finish, an additional roller grinding can be added to achieve the desired end result.

Deburring rotor and stator laminations is a crucial step in the production of electric motors, especially considering the requirements for precision and efficiency. With sheet thicknesses starting from 0.35 mm and an applied insulating layer, this process requires a high level of expertise and precision to ensure the quality and functionality of the laminations. One of the primary challenges is removing the punching burr without damaging the insulating layer. The operation is typically automated and linked to ensure continuous and consistent quality. An essential aspect of this process is bottom processing to ensure optimal accessibility and control over the deburring process. This allows for efficient removal of the punching burr while preserving the integrity of the insulating layer.
