CASE HISTORY

Tubular profiles are used in a vast number of applications on the market. Tubes in stainless steel, carbon steel, brass, copper and aluminium can be machined using laser cutting by Giulipas. Each sector prefers different material, based on the mechanical and aesthetic features and financial requirements.

To name but a few, brass tubing is widely used in the bathroom furnishing sector: elements such as shower columns, towel racks and toilet brushes are often manufactured with a brass tubing base.

Handles and railings instead are preferred in stainless steel. Industrial machinery chassis are mainly designed using carbon steel tubing.

What do all these tubes have in common? Machining using tube laser cutting.

For each tube requiring at least one hole, notch or any other geometry on the surface, tube laser technology is a great help in completely eliminating the costs to create punches or section moulds, instead increasing production speed, precision and quality of the cut.

Taking into consideration the aluminium tube, one application in particular where laser cutting of tubes is useful is the preparation of wheelchair parts. The support frame is a composition of perforated tubes adequately bent, where necessary. Cutting aluminium, thanks to fibre laser technology, today guarantees the best cutting quality and, in particular, speed. This solution was used for straight components of the wheelchair, and for those parts where bending is possible of the various items after laser cutting.

Instead, for those parts whose production process begins with bending, the solution implemented is to complete machining on the workstation available to Giulipas.

Giulipas has designed and manufactured stencils for part supports. This is a very delicate phase when dealing with items having been bent. This is because a good compromise is obtained between quality, precision of the machining and speed in set-up and part change times. Without overlooking the fact that bent items can vary slightly from one other.
