The TopGrinder by Q-Fin is a manually operating deburring machine that is suitable for various metal work processes like grinding, deburring, edge rounding and polishing. The TopGrinder allows you to deburr semi-automatically in a cost-effective manner. With this machine, Q-Fin enables the realisation of very high-grade edge rounding with little effort, straightforward burr grinding and even high-gloss polishing.

The TopGrinder is built ergonomically, robustly executed and especially safe because of the two-button control. This mobile deburring machine is standard equipped with a freely adjustable speed and a vacuum system, so that workpieces are clamped firmly onto the work station while you work safely. You can achieve great time savings compared to manual deburring, just because of the faster fixation of the product.

The balance arm allows you to adjust the grinding pressure to your liking, by means of the spring package, from floating to more pressure. The grinding head is equipped with two holders, enabling you to attach various grinding tools, from standard tools with an M14 fastening, to bowl brushes delivered by Q-Fin for the various processes.

The dimensions of the work area are 1280 x 780 mm. This makes the machine suitable for products up to 780 mm wide. However the front and the sides of the table can be easily lowered, so there is no actual maximum to the product length and also allows for wider products to be finished.

Suitable for processing:
• Stainless steel
• Aluminium
• Steel



The bowl brush ensures the rounding of the edges of the product, both on the outside as at any openings. Our standard brushes have a diameter of 255 mm. Depending on the material to be processed and the desired finish, different versions of brushes are available.


The grinding head is adjustable in various positions (angles) for different processes and grinding tools. Because of the double holders you can change from a brush to a grinding disk within seconds.

For the deburring of the product, you use a support pad with grinding disc. Depending on the height and hardness of the burr, you can set the grinding disc at a slight angle so that you can apply more pressure to the burr.

With the TopGrinder you receive a starter kit with abrasives and grinding materials. In addition to 1 brush (standard G80) various support pads and abrasive discs are included


Optionally, you can choose for a magnet system in the work surface of the TopGrinder. This magnet system is solely intended for ferrous materials and ferritic stainless steel.

The 2 electromagnets are located on the left and right side of the work surface and are very suitable to quickly fixate workpieces of these types of material. Apart from 2, we can also produce the work surface with 4 magnets. Pulling force 300 kg per magnet.
