FL Series

Automatic multiblade trimming machine

The DONATONI FL-type linear trimming machines are part of a wide range of trimming machines designed and manufactured for the single-pass longitudinal cutting of strips and tiles with indipendent positioning of multiple heads. Designed to meet the trimming needs of particularly hard materials—porphyry, slate, granite—they have since found application in the marble and granite sectors.

The main strenghts of the trimming machines type FL are:

- they have a support table made of a thick motorized rubber belt with adjustable forward speed according to the thickness and type of material to be cut;
- they have a device that automatically slows down the conveyor belt speed when cutting whenever any one of the cutting units exceeds its maximum installed power limits;
- they can fit a different number of units - up to a maximum of 5 - to adapt to varying processing and production requirements;
- they work with an independent belt drive system for each spindle/motor with the possibility of varying RPM depending on the type of material being cut;
- they can cut one after another different size slabs thanks to spindle/motor units that have independent drive movements.
- each unit has a display that shows the position of the spindle and makes it easier for the operator to make the cuts;
- they offer processing flexibility because each spindle performs an electromechanical vertical movement that determines the depth the disks cut into the material and also permit disks to be excluded from the cutting process;
- they have a system of side guides that ensure excellent trimming with good tolerances and constant dimensions in the cutting zone;
