ORT Italia specialises in the design and

manufacture of spline and thread rolling

machines for cold, hot and semi-hot

applications. The company dedicates a

considerable part of its revenue to research

and development, and its metrology lab

and testing rooms, recently refurbished,

allow performance trials and testing of new

installations. The company exports over

70% of its production, and has installed over

4,000 machines worldwide.

The

company’s

straightening

machine has been designed with special

characteristics that include high stability of

Straightening machine developed

structures, practical control panel, electrical

movement of the mobile heads, electronic

rotary motion transmission to the spindles,

and greater precision and speed in the

roller phasing operation. Linear guide ways

with pads also improve precision in slide

advancement.

Standard features include Siemens or

Fanuc CNC, electric axes, 30-ton capability,

spindle movement by brushless motor, high

precision on positioning slide (0.001mm),

velocity of positioning increase of 200%,

and structural rigidity increase of 60%.

Options include angular visualisation of

head, loader and un-loader

to individual design, electric

programmable back stop, tele-

service by web, automatic tilting

heads, and strain control.

The machine is free from

variations of temperature due

to the use of electromechanical

axis instead of hydraulic, and

also controls the torque on each

motor. The strokes are controlled

by Siemens inverter, and

slide positioning is individually

controlled by a linear encoder with a

0.001mm resolution. The head inclination

is monitored in the CNC with a resolution

of 0.02°.

The machine is equipped with a minimum

of three rolls, up to a maximum of nine,

depending on the length of the piece. The

straightening of sinterised camshafts is a

typical application.
