Milling

The milling process is a type of cold mechanical cutting performed through removal of material. It allows refining and transformation of raw components into finished parts thanks to the appropriate tool, which by rotating on its axis is responsible for removing metal parts. 

Typically, it consists of two distinct phases of roughing and subsequent finishing until it is complete, as defined by the technical design of the project. The milling cutter tool’s speed of the axis rotation and advancement allows precise adjustment of the incision, which mainly depends on the hardness of the material subject to cutting.

The most modern and technologically advanced CNC milling centres are made-up of automatic systems for replacing tools, to fully automate the production process. The equipment is structurally very sound, as it must absorb the significant vibrations generated by the motorised head, whilst containing the oscillations.

On hard materials or at very high speeds (thousands of revolutions per minute) lubricating liquids are also used for rapid cooling of the tips, so reducing friction as well. Furthermore, this lubricating substance also keeps back the chips, so they don't impact on the durability of the milling machine or damage the cutting wire.

On site, milling operations represent an important aspect of our work. 2V performs contract work always with an eye on tailoring projects. Our staff is fully trained and follows every project alongside the client with the utmost professionalism at every stage of the project.

Turning

Turning is one of the most important processes for finishing and processing metals. It is an industrial process carried out by removing parts using a rotary motion. This is even at high turning speeds combined with a close and mostly fixed and linear approach of the tool.

The parallel lathe is the most widely used in machining. The work motion is made by the rotation of the workpiece, while the tool runs parallel to the axis of rotation. The turning tools are made of high strength materials (steel, metal alloys melted, cobalt, carbides, etc...) as they are subject to extreme loads and are composed of different forms depending on the type of removal to be carried out.

Our qualified and skilled staff carry out turning operations with high precision numerically controlled equipment. This guarantees compliance with the design and tolerance limits required by the technical drawing.

2V is specialised in turning activities and is equipped with modern machinery able to guarantee quality and efficient manufacturing with rapid deliveries. Alongside our highly skilled staff, this new generation of CNC lathes enables us to reach high production standards and market competitiveness.

Special welding

Welding is a method that allows the fusing of two metal parts together, so ensuring material continuity. It is a common practice used in carpentry for the assembly of tools and metal elements.

Over the years, the company has developed a wealth of experience, certifying and specialising in the welding of metals and special weld beads. 2V is positioned as an ideal partner for this type of activity with particular reference to the petrochemical and mechanical sector.

Depending on the finished product to be manufactured, the company's certified technical staff is able to adopt the most advantageous typology. These special welding’s include the use of Plasma (PAW), equipment with MIG/MAG welding (GMAW) and a continuous cutting thread process, acetylene (OFW), TIG (GTAW) and electrodes (ESW) depending on the requirements.

In particular, we carry out welding using:

• stainless steel
• iron
• cobalt alloys
• Stellite
• aluminium

The welding process is performed with PQR/WPS (procedure qualification record/welding procedure specification) in compliance with EN-15614-1 / ASME Code.

Lapping

Metal lapping is carried out on a metal surface with the end aim of minimising its roughness to a higher or lesser extent until the surface is extremely glossy and transparent. The renowned mirror effect is achieved thanks to appropriate specific abrasives (typically silicon or aluminium) and represents the highest level of lapping. This makes surfaces smooth and homogeneous.

This process of precision finish is made on metals using a lapping machine and using abrasives, which are made to adhere to the surface of the tool itself, which is composed of soft material in terms of hardness.

This method of machining consists in carrying out operations to remove surface material. One of the fundamental characteristics of lapping is precisely the use of these abrasive chemicals, either in liquid or paste forms, which are inserted between the workpiece and the lapping support to hold the loose abrasive particles.

Polishing

Polishing metals is a type of operation that gives the materials treated a mirrored and completely uniform look. However, this operation is not only aimed at improving the appearance of metal items. In most cases, it is performed to remove all impurities from their surface to give a more effective and suitable appearance, so they can be fitted into specific contexts.

This technique gives the objects an extremely polished look, as well as being highly protective by increasing the surface resistance to general corrosion due to weather and wear.

Broaching

The broaching process enables the manufacture of complex profiles extremely quickly with very high levels of precision, higher than those reached through the usual milling process. It is based on a mechanism for removing metal chips to make teeth and grooves inside metal holes or to mould and shape external profiles. Thanks to this method, different kinds of components, sometimes of a very complex nature can be manufactured with extreme precision.

Such treatment is by means of specific tools featuring a set of teeth that are forced through the hole to be machined or against the outer surface of a metal piece, thus removing the quantity of material corresponding to the variation in space between one tooth and the next.

Equipped with innovative tools for broaching processes, 2V has a decade of experience in the manufacture of these operations even on complex materials such as steels and alloys in general. These involve advanced machinery that ensures greater precision and flexibility in machining.

Quality Control

Our quality management system is officially certified ISO9001. This is a commitment to continually improve our work and guarantee our customers maximum efficiency and quality standards throughout the production cycle.

The products manufactured on our premises are constantly measured and monitored with high-tech equipment such as an altimeter, surface roughness measurer, comparators, micrometres, thread plugs and P/NP DEA GLOBAL CLASSIC rings installed in properly air-conditioned environments. Thanks to dedicated software, all checks are carefully recorded on the report in an electronic form. They are then subsequently processed for statistical analysis.

The DEA GLOBAL Classic is a versatile measuring machine for the dimensional control of a variety of components. It can be equipped with sensors to measure point to point or, optionally, with scanning probes. The DEA GLOBAL Silver Classic is the ideal solution for our dimensional quality control. In the standard configuration, this CMM is fitted with sensors that measure point to point.
