Is a failure in your spindle causing defective parts and machine downtime?

Premature Tool Wear
A spindle with concentricity or imbalance issues causes accelerated wear of its cutting tools. This not only increases the cost of consumables but also reduces the efficiency and lifespan of all tooling.
Risk of Catastrophic Failure
An inadequate repair is an unacceptable risk. A poorly assembled spindle can suffer a severe malfunction, damaging the tool, the clamping system, and even the machine bed, significantly increasing costs.
Loss of Precision and Quality
Vibrations, marks on the surface finish (chatter), or dimensional errors are symptoms of a damaged spindle. Repairing the spindle is crucial, as each piece out of tolerance is a direct loss of material and time.
Lack of Specialized Technical Service
The repair of high-speed spindles is a high-precision discipline that requires a clean environment, specific tools, and deep knowledge. Finding a reliable and guaranteed supplier is the biggest challenge.

Our Process for Repairing a Precision Head: Methodology and Control in 4 Phases

O1

01

Contact, Advice and Safe Collection

The process begins with your call or form. Our team will ask key questions about the brand, model, and failure of your spindle. We arrange the collection with special packaging to protect this high-precision component during transport.

O2

Complete Disassembly and Technical Diagnosis

Upon arrival, the spindle is completely disassembled in our controlled environment laboratory. Each component is inspected and measured: concentricity, clamping force, condition of the cone, bearings, and sensors. With this diagnosis, we present you with a technical report and a detailed estimate.

O3

High Precision Repair and Assembly

With your approval, we proceed with the spindle repair. This includes con grinding, replacing precision bearings, dynamic balancing of all rotating components, and any other necessary actions. The assembly is carried out following the strict protocols of the manufacturer.

O4

Testing Bank, Final Report and Delivery

The assembled spindle is installed in our test bench for a run-in cycle. We monitor the temperature and vibrations in real time until stabilization. We deliver the equipment with the final test report and warranty, ready to be assembled and produced with maximum precision.

WE WILL GET BACK TO YOU AS SOON AS POSSIBLE!
