Independent cutting stations

Technology that is used to increase a beamsaw´s output and to flexibilize it´s production.

Traditional program fences confine themselves to move a workpiece to only one position; after that the cutting process is accomplished; the cut stripe is pushed out to the front (to the operator) to take the next position. As a result the operator receives several stripes that have to be stored temporarily on the flotation table to be rotated for the second cut and to be fed back to the machine in the correct order.

The significant advantage of machines with separate program fences are the parts of the program fence (in most cases these are two grippers) that are moving independently of one another. Besides they can be positioned NC-controlled. Those advantages allow simultaneous accomplishment of the first rip cut to the raw panel as well as of the final cross-cut to the already cut stripes.

Originally this technology was only used for angle plants with two or three program fences in the cross-cut saw (for example: HOLZMA´s models HFL and HFV). The angle plant´s advantags are the continuously cutting length machine and the cross machine that is cutting the stripes into smaller finished parts without temporary storage. Since single machines have a much higher share in the market it was a logical consequence to introduce the technique of simultaneous accomplishment of rip- and cross-cuts in the field of non-industrial and low volume production.

In the middle of the 1990s Casadei offered a solution for single saws. The models of production series SP (for example SP 45D, year of manufacture: 1995) were equipped with two independently working program fences that were able to position panels/stripes differently.

In 2000 this technology achieved a breakthrough when the company Giben used it in the single saws of the production series Formula. Other manufacturers adopted this technology and continued to developed it.

Implementation of this production principle:
