NUMROTOplus® programming system

With NUMROTOplus®, a flexible and reliable programming system, an enormous variety of tools can be manufactured and resharpened.

Every detail of the individual tools can be changed and thus adapted to Customers needs. NUM's future-oriented systems optimize the performance and profitability of our tool grinding machines.

New production

The grinding process on the machines takes place continuously at high speed with maximum precision in the µm range, even for big quantities or long cycle times.

Tools resharpening

Worn cutting, drilling, milling and gear cutting tools can be brought back to full efficiency and high surface quality and made operational again by precise resharpening.
