Q-Fin TopGrinder – Deburring, grinding, edge rounding and polishing

The TopGrinder by Q-fin is a manually operated machine that can be used for various metalworking 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 surface are 1200 x 780 mm. This sets the maximum dimensions for a workpiece at 780 mm. There is no maximum length because the sides of the table can be easily lowered

Materials that can be processed:

  • Stainless steel
  • Aluminum
  • Steel

Grinding material
The brush ensures the rounding of the edges of the product, both on the outside as at any openings. The 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. The Q-fin brushes and the majority of the tools available on the market (M14 fastening) can be used.

Magnet system
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.
