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. Technical characteristics Fanuc control. Brushless and torque motors (A) for high dynamic range of operations. High precision positioning on linear and rotative axes. The longitudinal axis (working table) and the transversal axis (carriage support head) have rail with rolling friction. Linear axis with re-circulation ball screws (grindind and preload) to reach high preci- sion. Driving axis A with technology“directdrive” for precision positioning. All surfaces of support and contact are grinded. Positioning system on the axes with optical lines and high resolution encoder directly connected to the operating parts. Electric spindle with a wide range of rotation speed for a precise calibration and to reach better cutting conditions.
