Punching and laser cutting from coil: how to generate 197.400 Euro in profits per year

New and innovative technologies can increase the competitiveness and profits for OEMs and sheet metal fabricators. The previous article showed how the material savings can reach as much as 15,9% when moving to modern coil fed punching and laser cutting lines.

The second great advantage of coil fed lines is the higher production speed. In particular, today's punching and fiber laser cutting machines are combined in production lines that execute the punching and laser cutting operation simultaneously. In many cases the cycle time is reduced by more than 50% compared to traditional punch/laser lines, where the parts are first punched, and then laser cut.

As promised, this article completes the case history of company Elleci: it will show how the company is taking advantage of the high production speed of its coil fed punch/laser line, generating additional 102.200 Euro in savings per year which when added to the saving in raw material, totals 197.400 Euros.

Coil fed punching and simultaneous laser cutting: structure of the line

Here is the layout of a typical coil fed punching and laser cutting line. The line is divided in three main modules: decoiler, punching unit and laser cutting unit.



The punching unit and the laser cutting unit work independently.

First, the punching machine processes the punching and embossing operations on the coil and then shears the punched blank.

Then, the product is delivered to the laser cutting unit through the roller bench; the laser unit uses a vision system to identify the position of the panel and to set the laser cutting operation to the pre-cut holes.

The high speed of the process is due to:

1) The continuous process from coil eliminates the loading and unloading time (present in all traditional sheet fed machines).

2) Laser cutting and punching operation take place simultaneously and in parallel.
