Galbiati Group is a partner of leading equipment manufacturers and users in the steel industry.

For years we have been providing contract drilling, milling, and turning of components for the steel industry.
We manufacture units or complete machines, such as: machining of mill housings up to 120 ton, chokes, large screws and nut screws, accessory units such as bending blocks, and other requests based on customer needs and specifications.
Machining and assembly of complete units for:
shears
spindles for coilers/decoilers
segments for continuous casting
straighteners
pinch–rolls or press rolls.
We also offer the services of our assembly department for mechanical assembly and “pipingof the hydraulic and lube systems.

Galbiati Group has been working with major manufacturers of metal forming presses for decades, that apply a variety of technologies for production, blanking, drawing, and hot and cold forming.

In particular, customer support activities are aimed at the machining of the main structural parts of the press, such as the bed, crown, uprights, slide, or  one-piece frames, such as for horizontal presses.

Galbiati customers also benefit from an assembly pit with 13 m height under hook, 120 ton crane, and painting booth.

We perform contract machining of mill housings.

Mill stand housing machining is carried out on CNC machine tools. The final geometry is inspected with a CAM2 Laser Tracker Xi system to ensure that all working and backup surfaces are within the requested dimensional tolerances, flatness, parallelism, and squareness.

Galbiati group has the equipment and technical skills to manufacture medium and large sized gearbox housings.

For years we have been working with Italian and foreign industry leaders supplying and machining gearboxes for the ship building industry.

Dimensional check and inspection is very important for the construction and machining of marine gearboxes. This is performed using our Zeiss three dimensional inspection machine. As these are internal parts subject to high rotational speeds (for example the pinion shaft and gears), maximum precision is required.

Galbiati Group has a very close relationship with major Italian machine tool manufacturers that has gelled over the past decades. Through the continuous renewal of its machine tools, Galbiati is capable of machining components to very high quality standards so that the final product (machine tool) always meets the precision required by the user.
The group is specialized in contract machining of major structural parts, such as the machine bed, columns, heads, and tables.
This high precision is possible thanks to the inspections performed using the Zeiss dimensional inspection center.
