Blade Surface Milling
CNC-controlled 3D milling of damaged blade surfaces - uptower or on ground - leaving an exact, consistent surface ready for a prefabricated repair segment.

How It Works Machined Repair Surfaces.
Machined Repair Surfaces.
Not Manual Grinding.
Glass fiber and carbon blades can break due to physical damage or casting defects. Our CNC-controlled 3D milling machines the damaged area to an exact, fully definable surface - instead of slow manual work.
How the repair works
The machine performs 3D milling on the defined area of the blade. After milling, a prefabricated carbon or glass fiber segment can be inserted into the machined pocket, restoring the blade with a consistent, repeatable result.
Uptower or on ground
- Uptower: a compact milling unit mounts directly on the blade surface
- On ground: a gantry milling machine handles larger defined areas
- Exact surface after processing - fully definable area with consistent finish
Why machine instead of grind
Manual surface work is slow and operator-dependent. Machining the area is less time consuming, gives an exact surface after processing, and makes a prefabricated insert possible - the pocket and the insert are cut to matching geometry.
Technical Specifications
Method 3D milling, CNC controlled
Blade materials Glass fiber, carbon
Repair location Uptower or on ground
On-ground equipment Gantry milling machine
Result Exact, fully definable surface
Exact Surface Machined - not hand-ground. Consistent surface across a fully definable area.
Less Time Consuming No manual surface work. The machine mills the defined area in one controlled operation.
Prefabricated Insert The machined pocket accepts a prefabricated carbon or glass fiber segment.
Uptower Or On Ground Compact unit on the blade uptower, gantry machine for on-ground repairs.

FAQ
Frequently asked questions
Can a damaged blade surface be repaired by machining?
Yes. A CNC-controlled machine performs 3D milling on the defined damaged area, leaving an exact surface. A prefabricated carbon or glass fiber segment can then be inserted.
Does blade surface milling work uptower?
Yes. A compact milling unit mounts directly on the blade surface uptower. For on-ground repairs, a gantry milling machine handles larger areas.
Why machine the surface instead of grinding it manually?
Machining removes the manual work, is less time consuming, and produces an exact, consistent surface across a fully definable area - which also makes a prefabricated insert possible.
