3D Scanning Handheld ZEISS 3D laser scanning on site. Reverse engineering, CAD comparison, wear and damage analysis - metrology-grade digital documentation. CNC Onsite designs and builds proprietary mobile machining systems — from prototype to production-ready — for wind and heavy industry.
"Do you need to start the repairing process as fast as possible, typically we can use our prototype machine to carry them out. When handing over the final machine, you can increase the speed and optimize your repairs.
Validate the solution early and shorten the development cycle from concept to finished machine.
Start addressing the challenge using a prototype solution while the final machine is being prepared.
Reduce waiting time and restore operations sooner by testing and deploying solutions earlier.
Confirm tolerances, functionality and performance before committing to full-scale development.
You bring a machining challenge conventional methods cannot handle efficiently.
We propose a solution and assemble a prototype from existing building blocks — ready within 14 days.
Collaborative test verifies the prototype performs within required tolerances and speed.
Based on test data, we finalise machine specs: process time, operating context, investment.
Full solution with FAT, SAT, and handover. Repair format agreed: our team, yours, or shared.
Training provided. Optional add-ons: maintenance, support agreements, and delivery additions.
Mobile flange milling system for large-scale precision machining of tower flanges, monopiles and transition pieces.
High-Precision Flange Milling for Serial Production. Hercules is CNC Onsite's latest generation flange milling machine, developed to deliver the same industry-leading precision as Goliath while significantly increasing efficiency in serial production environments.
Mobile 4-axis CNC gantry milling machine for on-site high-precision machining of holes and surfaces in large structures.
Customer-adapted sibling of Kermit — named after its blue colour. Tailored for a specific repeat-repair challenge.
Describe your challenge. Our engineers will assess whether an existing machine fits — or design one that does.
