CNC machining for high precision
CNC machining is carried out in vertical or horizontal machines at high speed. Fixtures make it possible to achieve rational and efficient production. We handle CNC machining in lengths up to 10 000 mm.
Common CNC processes:
- Milling – Provides a surface finish of 1-3 Ra thanks to high speeds.
- Drilling – Requires special aluminum drills for optimal results.
- Turning – Provides a very good surface finish by rotating the workpiece.
- Threading – Performed internally and externally with cutting threading tools.
Bending of aluminum profiles
Bending makes it possible to create finished components from a single profile, reducing the need for joining. We process profiles up to 7 meters long using different methods depending on series production, radii and tolerances.
Common bending methods:
- Draw bending – High precision and good automation potential, suitable for medium and large series.
- Roll bending – Suitable for simpler cross-sections and large radii, low tool investment.
- Press bending – Cost-effective method for large series with high accuracy.
- Stretch bending – Provides extremely high precision but involves higher costs.
Important to consider when bending:
- Minimum bending radius: 3 x d
- Strive for a symmetrical profile
- Bucking operation in T4
- Surface changes, e.g. “orange peel surface”
Joining of aluminum profiles
To create durable and functional structures, we offer several joining methods, adapted to your needs and application.
Common joining methods:
- Fusion welding (TIG & MIG) – TIG produces fine welds for thin-walled materials, while MIG is faster for thicker materials.
- Cold press welding – joins aluminum pieces without heat through high pressure.
- Riveting – Pop riveting without backing or stucco riveting with backing.
- Soldering – Suitable for thin materials and small details.
- Bonding – Uses epoxy or polyurethane adhesives for strong joints.
- Screw joint – A flexible method that allows for dismantling.
- FSW (Friction Stir Welding) – Creates a strong joint through friction heat.
