Smart Rolling Machines

Evirt Italia s.r.l.
Thread rolling machines for bolts and screws

PLANAR 120 Synchro

EVIRT PLANAR machines? series is the most flexible Rolling machines? series. Being equipped with Two-Independent Moving Slides, this group of machines are not only useful for threads, knurls and profiles rolling, conversely their main field is the production of splines (including little gears) and worm screws components as well as Ball Screws production for which the PLANAR series rolling machines has been deeply tested and approved as capable of producing 100% C3 Class Ball screws on various material up to HRC 32.

Another really notable innovations of EVIRT Italia engineers made possible by the PLANAR Rolling Machines is the rolling of splines with circular dies technology.

Due to the full independency between the two pushing heads, EVIRT PLANAR Rolling Machines can be used both in symmetrical and asymmetrical pushing operations.

The machine is perfectly fitting any loading and feeding system, without requiring any loader displacement when changing the components geometries.

The PLANAR model has been developed to allow fast and precise infeed and throughfeed rolling operations and it can be equipped with two different spindles management configurations:

SYNCHRO version - each spindle is directly connected to a Brushless motor through a high torque planetary gearbox;

GEAR version - all the spindles are managed in group through a single transmission moved by an asynchronous motor controlled in frequency (Siemens INVERTER).

Characterized by the inventiveness and flexibility that has always distinguished the Italian companies, a further service that EVIRT Italia is providing to his customers is the on purpose design and production of Alternative Machines for forming processes.
Based on its long experience in automation and engineering, the EVIRT Italia R&D department, as well as its Technical department, is well known for his ability to supply fully customized projects for customer dedicated machines.
Some famous example of common projects are below mentioned:
FIN TUBES ROLLING MACHINE ? FINs Series
The FIN Tubes Rolling Machines represents a specially designed RADIAL Rolling Machines dimensioned and structured to fit all the particular needs of Extruded Finned Pipes? Production.

The main advantage of Extruded Finned Pipes is the easier and faster transmission of the heat on many kind of pipes for internal circulating fluid. Moreover, this rolling process presents notable advantages like:

Lower Production Time.
Lower Production Cost.
Improved Mechanical Properties of material.
Outstanding Surface Quality.
High Precision.
No Material waste.
Born from Radial machine, the FIN Tubes are equipped with three rolling spindles driven by directly connected brushless motors, which can provide high rotating speed up to 1000 rpm. The main lead of the EVIRT Italia FINs Machines is the almost unlimited connection with automations, their short cycle times and the ability to make a quick and fully automatic setup, mainly represented by automatically motorized control and actuation of the precise spindles? swivelling angle ? the most relevant parameter in affecting the fins? quality.

Each spindle present a dedicated tools? support where the finning discs are assembled in an intuitive and quick way.

As well as any EVIRT Italia machine, the FINs models can be equipped with PLC or CNC control unit.

FIN series? Force is ranging from 100 kN to 2400 kN, while the Pipes Diameters range is included between Ø 10 mm and Ø 140 mm.

ROUND BURNISHING MACHINE ? BMs Series
Born as complementary accessory for the rolling machine, the Burnishing Machine has developed its own market thanks to its ability to provide super finished surfaces on round components like bars, pneumatic cylinder stem, motor crankshaft, coupling pins, etc. The main advantages of using a rolling process to Super Finish cylindrical surfaces are the reduced production time, the improved mechanical properties of the rolled material and the saved costs due to zero material waste.

Equipped with a single hydraulic pushing slide and a series of rotating tools (related to the workpieces? needs), the machine is suitable both for infeed and throughfeed Superfinishing Rolling processes to be perform on cylindrical surfaces, including also slightly conical ones.

This machine?s series is suitable to work parts having a diameter range within Ø 2mm and Ø 165 mm, while the burnishing force is ranging from 40 kN to 100 kN.

Thread rolling machines for bolts and screws
MONO 20 Synchro
EVIRT MONO machines? series is the long-lived rolling machines and the reliable one. Characterized by One Single Moving Slide and Two Rotating Spindles, the machines of the MONO series are suitable for rolling standard threads and profiles as well as cold forming on cylindrical components according to the most common thread standards (ISO, ACME, TPN, WORM SCREWS, etc.).

The MONO machines are engineered and designed to perfectly adapt the economical manufacturing solutions as well as the high productivity manufacturing lines.

The main lead of the EVIRT Italia MONO line machines is the almost unlimited connection with automations, their short cycle times and the ability to make a quick and fully automatic setup - few seconds for pitch-finding during dies changeover.

The MONO model has been developed to allow fast and precise plunge and throughfeed rolling operations the spindles management for this series:

SYNCHRO version - each spindle is directly connected to a Brushless motor through a high torque planetary gearbox;

GEAR version - all the spindles are managed in group through a single transmission moved by a single asynchronous motor.

Three dies thread Rolling Machine
Evirt Italia s.r.l.
Thread rolling machines for bolts and screws
Radial 50 Synchro
EVIRT RADIAL machines series represents a highly stiff Three-Moving Slides Rolling Machines engineered and designed for various types of threads and profiles rolling. The machines included into this series are mainly suitable for threading and cold forming on cylindrical hollow components, like nipples connections, hydraulic and nuclear pipes, civil reinforcing screws and similar products.

Moreover, the EVIRT ITALIA Radial machines have been engineered and deeply tested to perform high quality Ball Screws up to C3 Class.

EVIRT RADIAL series is characterized by three moveable pushing heads and three rolling spindles, while its pressing force ranges from 100 kN to 1500 kN.

Due to its capacity of auto centring, the RADIAL? series is often used in rolling of cylindrical parts with important diameters as columns, pillars and similar components.

The RADIAL machines series has also been approved as able to provide 100% C3 class Ball Screws products.

The main lead of our EVIRT Italia RADIAL series machines is its high rigidity and automation. Due to brand new machines? main frames, together with its high automation level, the machines of this series are the most easy use rolling machines nowadays available on the market. In addition to this aspects, really appreciated are also its available features able to perform the complete machine?s setup in a fully automatic and independent way.

The machine has been more and more approved by rolling producers also due to its low power consumption, easy maintenance and low level operating noise.

The RADIAL machines models have been developed to allow fast and precise infeed and throughfeed rolling operations and its spindles management is available in two different configurations:

SYNCHRO version - each spindle is directly connected to a Brushless motor through a high torque planetary gearbox;

GEAR version - all the three spindles are managed in group through a single transmission moved by an asynchronous motor controlled in frequency (Siemens INVERTER).
