NU5A Compact Sharpener with laser scanning

 4 essential characteristics

Compact overall size

The compact dimensions allow easy and problem-free installation and integration in production lines.

Ease of use

The NU5A COMPACT SCAN does not need specialised operators. Training on how to use the machine requires a very little time. Ordinary maintenance is reduced to keep the machine clean. Skilled operator could adjust the geometry of the tool if necessary, assisted by the software that prevents any mistake.

Technology Informations about the tool are automatically collected by the software through the laser. It is easy to verify the geometrical properties of the tool to be ground. An automatic procedure also allows to check and compensate the shape of the grinding wheels. Software automatically warns about ordinary operations (wheels measuring, wheels dressing and warm-up).


For companies, reducing power consumption and working times is extremely important:

• to limit energy consumption and therefore environmental impact

• to make the production process more efficient

The NU5A Compact Scan achieves both of these objectives: in terms of consumption, the energy required is reduced by 60%, ensuring fast operating speeds for cleanliness and precision.
