Axle & Shaft
Repair

Precision machining of damaged and worn axle and shafts. Reducing downtime, repair costs and operational disruption.

How It Works

Precision machining
For Axle & Shaft repairs

Damage to critical shafts can occur due to wear and tear or during maintenance, disassembly, or component replacement. On generator shafts and other precision-machined interfaces, even minor surface damage can prevent correct assembly and compromise the performance of the surrounding components.

Rather than replacing the entire shaft, CNC Onsite restores the damaged area through precision machining. The damaged material is removed in a controlled process, creating a new reference surface with the required geometry. A new ring is then installed onto the shaft, restoring its functional dimensions and providing a new wear surface.

The repair is designed for applications where accuracy is critical. By restoring the shaft instead of replacing it, operators can avoid extensive component replacement while returning equipment to service faster and at a significantly lower cost.

Developed in response to repeated customer requests, CNC Onsite's dedicated shaft repair solution combines advanced CNC-controlled machining with the flexibility needed to perform high-precision axle and shaft repair on wind turbine generators or other industrial machinery on site.

Repair Instead of Replace Keep critical assets in service by repairing damaged shafts instead of replacing them, reducing downtime and avoiding disruptions to production.
Reduced downtime Restoring damaged shafts is often considerably faster than sourcing and replacing major components, helping operators return turbines, generators, and industrial machinery to operation sooner.
Precision machining The repair process is designed for applications where accuracy is critical.
Reducing total ecenomy Avoid the costs associated with replacement parts, extended downtime, and major disassembly by restoring the damaged shaft instead.
How it works

Our Process

01

Quotation

The manufacturer contacts CNC Onsite to discuss specifications for the monopile flanges. Our technical sales team will analyse the project and customer schedule. We will issue the quote based on the customers need and timeline. The customer issues the purchasing order.

02

Planning

We plan the technical part of the project, which includes preparation and programming of Goliath, the precision machine that will perform the milling. We plan staff availability and timing, including flexibility to accommodate potential changes to the schedule.

03

Implementation

Our technicians will conduct the precision milling of the flanges at the customer’s factory. Alternatively, CNC Onsite will train the customer’s own technicians for the operation of the machine. The team will use the Goliath machine to mill the flange faces, leaving them flat to within one millimeter.

04

Handover

After machining measurements are made, a measurement report is issued to the customer. Alternatively, the customer or a customer-contracted third party conduct the measurements. Once the measurement are complete, the customer signs off the work.

05

Follow-up

We offer follow-up meetings with the customer. CNC Onsite’s follow-up program is part of our high quality standards.
