Special rollers and shafts

Blade holder rollers

The blade holder rollers are rollers characterized by the presence of milling, on the table, of different shapes necessary for locking the blade.
The function of this type of roller can be the clean cut of the product or the engraving. On the surface of these rollers, in addition to the milling, dedicated to housing the blade, it will be necessary to have a locking that can be done with wedge systems, or with simple screws.

The surface, not being in contact with the product, is usually finished by lathe. On request, to protect the roller more, it is possible to coat the area with thick chrome plating and grinding, non-stick, carbide or ceramic coatings.

rulli-trituratori

Shredder rollers

The shredder rollers are very similar, in terms of construction, to the blade holder rollers. The main difference is that the blade is mounted with a straighter angle. The function of these rollers is to shred the product so as to bring it to the desired sections.

The surface, not being in contact with the product, is usually finished by lathe. On request, to protect the roller more, it is possible to coat the area with thick chrome plating and grinding, non-stick, carbide or ceramic coating.

Shafts dedicated to the drilling sector

The shafts dedicated to the drilling sector have the purpose of transmitting the motion from the motorized part to the actual working and suction part.
On these shafts, we can carry out the most varied precision workings according to the customer's needs.

alberi-valvole-farfalla

Shafts for butterfly valves

The shafts dedicated to the butterfly valves have the purpose of transmitting the motion from the actuator to the disc, so as to regulate the flow of fluid (gaseous or liquid) inside the duct.
These shafts consist of a one-piece stem that has a high resistance. Upon the shaft, there is the presence of key seats, which allow the connection between the stem and the disc.

Given the high precision required, these stems are subjected to final grinding and usually, working in highly stressed environments in terms of corrosion, they are made with materials such as stainless steel, duplex, super duplex, inconel, xm19.
