The groove is the best method for restoring the contact plane, maintaining blade efficiency and providing a new cutting surface.

The groove and the slight off-centre location of the hole eliminate the need to turn the blade at the end of cutting, with considerable saving during fitting.

The operation can be performed in any cutting phase and is an alternative to the traditional methods using oxyhydrogen flame and pneumatic shears.

Fitting.
The blade must be fitted with the grooves facing downwards. The fitting method does not change.

Restoring the cutting surface.
Consists in removal by breakage of the non-worn area of the blade along the groove.
It is performed manually by means of an appropriate tool used on the part to be removed.

Ferriera di Cittadella recommends the following tool specifications: gap depth 15 mm, maximum width 7 mm, corners perfectly squared.

The FC Plus is a patented idea and is protected also as a trademark.
The characteristic of this blade is unique and cannot be reproduced outside the FC factories. The advantages of the blade are guaranteed and developed by the Ferriera di Cittadella research and development department.

The tests performed have provided satisfactory results and guarantee innovation of the blade together with advantages in terms of working time and protection of employees against the accidents that occurred with the previous techniques for removal of the worn material.

Today this blade is used as a matter of course and is considered an integral part of the new sawing systems.

Research & Development

Blades for Granite: Tradition and Innovation
Always a leader in stone cutting, in addition to producing the innovative diamond wire used for granite cutting, Ferriera has extensive experience in the production of saw blades for granite, a historic product still used in some areas of stone processing.

Grooved Saw Blade: A Revolutionary Innovation
In the 1960s, the grooved blade for marble was developed from a French patent, which Ferriera di Cittadella adapted for granite cutting by modifying the mechanical and chemical properties of the materials. This led to the creation of the grooved blade for granite, an exclusive product of Ferriera di Cittadella, designed for perfect cutting and low abrasive consumption during polishing, optimizing processing costs. This type of saw blade has never been matched by competitors, both in terms of quality and technical features.

Pre-Tensioning: Quality and Reliability
The pre-tensioning (“stretching”) technology, developed by Ferriera, prevents deformation of granite cutting blades, ensuring greater stability during use, longer lifespan and maximum precision in cutting.

Custom Blades for Every Need
Ferriera produces granite sawing blades tailored to specific thickness and size requirements. Our expertise in rolling thin gauges allows us to offer superior-quality products.

Ferriera: A Trusted Industry Leader

Founded in 1956, Ferriera has played a key role in the history of granite blades, which are still valued in certain specialized fields. Our expertise in hot rolling and technological innovation enables us to provide reliable solutions for granite cutting.
