Automatic Straightening Systems

1890 Our Heritage Founded in 1890 and fully owned by the Galdabini family, the company has its headquarters close to Milan. The company has always been innovative - the initial artisan activity of maintenance and repair of the local textile factory soon evolved into the construction of machines for the mechanical industry. Nowadays, we design and manufacture automatic and manual straightening machines, hydraulic presses and universal testing machines. With more than 125 years of experience in the machine tools industry, our machines are found in applications and industries such as automotive,...

Straightening means: measuring workpiece deformation, evaluating deviations in relation to the requested tolerances and pushing on the part to reduce its deformations. Factors causing distortion: • Heat treatment; • Stresses from manufacturing processes; • Material handling. Precision straightening is the key factor in achieving the following advantages: • Reduce costly machine operations such as turning and grinding; • Improve final geometry of the part (more uniform, better gear geometry); • 100 % final inspection of parts. Our experience in straightening gained over the past decades has led...

Straightening technology is applied through the use of: • Measuring sensors; • High-precision equipment specially designed to deal with workpiece deformation; • Controlled stroke to provide exactly the right force required in the process (bending or hammering). Measurements for straightening are mainly related to runout, linearity and circularity errors. Shafts: Workpiece deformation is measured before and after the straightening process by means of a 360° rotation of the workpiece itself. Runout measurement allows the detection of both deformation and error of form. The error of form is separated...

Vertical Straightening “C” frame movable table Straighteners Our PAS vertical straighteners are electromechanical machines designed for straightening short and medium length shafts. Their innovative C-shaped frame and the movable table holding workpieces are two important features which are ideal for producing large quantities of parts as well as small batches. The electromechanical technology enables: energy saving and reduced floor space, flexible layout, low noise level, accessibility from three sides, and reduced maintenance. The force is generated through recirculating ball screws and is...

Horizontal Straightening 2 in 1 Straightener for linearity and twist correction Pioneers in the 80s with the development of the first horizontal machine, today Galdabini produces TWIN machines specifically designed for straightening long profiles. The system allows precision straightening and short cycle times; these conditions make the TWIN machine the only global solution for long profiles. The system is unique in its kind - the TWIN offers the combination of longitudinal (X-Y axis) and torsion straightening in a single machine. The profile lies free on supports and force is applied horizontally....

Heavy duty Straightening Heavy duty Straightening systems Heavy duty automatic straightening machines have greatly improved over the past few years, through the use of sophisticated kinematics, actuators and electronics. Application in fields such as energy, oil and gas, steel mills and hydraulics, require processes which guarantee high quality finished products. Tubes, round and / or square bars, profiles, which until the recent past, were straightened almost exclusively through the rolling process or by simple manual presses, can now be precision straightened - the only way to ensure achieve...

Heavy Duty Straightening Horizontal Straighteners for linearity and twist correction The STEP model is the best solution for straightening workpieces with a constant section: profiles, rails, round, hexagonal and rectangular bars. The machine is designed for automatic straightening of workpieces (very long and thin), along X-X and Y-Y axes, in one single cycle, without any interruption or any operator intervention. The machine consists of a robust and compact monoblock frame to minimize the required space and offers the user a complete overview of the straightening area (lean concept). The reaction...

Ring Rounding Machines to measure and correct Roundness The RING straightening machine allows the measurement and straightening of rings: car gearbox synchro rings, epicyclic sun gears, bearings and wind power rings. Control is accurate and avoids the use of external equipment (off-line checking), eliminating production downtime. The horizontal machine frame allows easy workpiece loading and accessibility on 3 sides. The clamping expansion assembly for ring drive is controlled by a high response and accuracy brushless motor. The machine applies the concept of horizontal straightening and allows...
