From sawing, drilling, and milling to deburring pipes and profiles as well as preparation for welding – with our flexible, high-performance TRUMPF laser pipe cutting machine we do everything in just one step.
This highly productive process can be used with a wide variety of profile materials and even pipes with diameters up to 250 mm and wall thicknesses up to 8 mm. Costly post-processing is nearly eliminated due to the high cutting and dimensional precision achieved when pipes, profiles, and cut edges are laser processed. Individual components for tubular frame constructions for small to large-scale series can be fabricated more effectively than with conventional processes. You save time and costs while maintaining consistently high quality.
Flow drilling technology
Often just one or two threads can be cut into very thin-walled pipes and profiles. Generally, this does not produce a reliable connection. We use flow drilling technology in order to cut a larger, more supportive thread in thin sheet material.
In the flow drilling process, a specially ground, carbide tool drills though the workpiece without producing chips. In contrast to normal drilling, material is not removed; instead, the force and frictional heat plasticize and displace it. This causes a bulge to form on the lower side of the hole, causing the wall thickness to increase by approximately a factor of three. Within a few seconds, stable holes are formed in the workpiece. This makes both thread cutting and elaborate constructions with rivet nuts, weld nuts, and insert nuts unnecessary.
We use flow drilling for all common material thicknesses from 0.5 mm.
Your benefits
- Combining several work steps (sawing, drilling, milling, and deburring) results in highly productive tube and profile processing
- High-precision cutting and an exact fit
- No costly post-processing
- Cuts that are free of burrs
- Flow drilling replaces both thread cutting and elaborate constructions with rivet nuts, weld nuts, and insert nuts; high-precision, chipless production that uses less material and considerably fewer process steps than drilling
