The universal grinding machine Nesi, with 1 – 4 controlled axes, is the expression of Nesi’s continuous technological research.
To obtain design targets, rail with rolling friction have been installed on the longitudinal axis (working table) and transverse axis (carriage support head), with the dual benefit of smoother travel combined with increased working load.
The electric spindle has a wide range of speeds, thus allowing accurate calibration for the best cutting result.
Processing typologies
Cylindrical mills: cutting angle and first and second dorsal rake angle of both axial and radial cutting edges.
Taper mills: cutting angle and first and second dorsal rake angle on both axial and radial cutting edges.
Three edge mills: dorsal rake angles.
Given the extreme precision of the machines, it is possible to grind flat surfaces, cylindrical holes and small part shafts.
Countersink tool: angle on curved surface.
Taps: mating angle.
