GP Usinagem specializes in on-site machining, performing machining services directly where the equipment operates. We carry out precision machining, adjustments and component repair, reducing the need to dismantle and transport equipment.
We work quickly, precisely and safely, bringing the resources and technical expertise to the client to solve machining needs on industrial machines, equipment and components, while minimizing operational downtime.
We machine the component in place, directly on the equipment.
No need to move large parts to an outside machine shop.
Your operation is back up and running sooner.

We offer a wide range of on-site machining services, including adjustments, component repair and precision machining. Our highly qualified team uses state-of-the-art portable equipment to deliver accurate, efficient results.

We repair and machine shaft ends with high precision, restoring the part's original dimensions, alignment and strength for safe, durable and high-performing operation.

We perform high-precision line boring, delivering dimensional restoration, accurate alignment and an excellent surface finish.

Milling of bases and support surfaces to tight dimensional tolerances, ensuring flatness, leveling and geometric accuracy.

Machining of flange faces, raised face diameter, flat face, serrated face and RTJ grooves, ensuring dimensional accuracy, concentricity and reliable sealing.

On-site machining (also called field or in-situ machining) means performing machining work directly where the equipment or component is installed, with no need to dismantle it and ship it to a machine shop. This makes it possible to machine shafts, flanges, housings, bores, faces and other components right at the industrial plant.
On-site (in-situ) machining is carried out directly on the equipment or component in the industrial area. The technique is used when removing the part is impractical, too costly or could cause an extended production shutdown.
Quality in on-site machining is ensured through strict control of alignment, cutting parameters and technical measurements. We use precision instruments such as dial indicators, micrometers and bore gauges, along with proper machine mounting and continuous dimensional checks throughout the process, ensuring tolerances and surface finish meet specifications.
On-site machining covers a wide range of repairs and modifications, including shaft machining, housing repair, flange machining, line boring, facing, drilling and bore repair, component fitting and other operations performed directly on the equipment.
In conventional machining, the component is usually removed from the equipment and taken to a machine tool. In on-site machining, the machines and tools are brought to the job site, so the work is performed directly on the installed component.
In many cases, yes. Because the work can be performed on site, there is no need for complete dismantling, transport and subsequent reinstallation of the component. This can eliminate steps from the job and help reduce equipment downtime.
