Laser Cutting of metal sheets CMM is one of the leading European companies active in the field
of laser cutting of metals. The company has 3 laser cutting systems able to process steel plates with the maximum size of 4000x2500 mm, the power of the laser sources reaches up to 4400 Watts. What distinguishes CMM in the market of laser processing of metal sheets is the organizational method applied, over the years actually considerable expertise and skills have been gained and developed in all stages this type of processes involve. CMM, being one of the first Italian companies that made considerable investments in this specific field, can boast a very large number of customers and this allows it to optimize the laser cutting process with very advanced nesting. Often on the same metal sheet more laser cuts are made to satisfy the order of more than one customer, thus reducing total waste and, consequently, the cost for the end customer. Every year more than 16000 cutting hours are
worked for different and various sectors. CMM supplies special parts cut with the laser technology for many fields: carpenters' workshops,
manufacturing of agricultural machinery, construction of steel structures for the PV industry, mechanical engineering ,
spare parts for excavators and components for the automotive industry. Regarding workable materials, CMM is able to process s235, s275, s355 carbon steel.
Normally also laser cuts are carried out on Domex, Hardox and Corden sheets with a maximum thickness of
20 mm. CMM is also able to meet the needs related to stainless materials, being able to cut the most common Aisi 304, Aisi 316, but also other stainless steels intended for other types of uses, such as boilers or industrial and energy plants.
The MachinesIn the sheet metal processing department CMM has installed 3 Bystronic laser cutting systems equipped with automatic loading and unloading.

Metal Sheets folding: Maximum length 4 metres Folding metal sheets is one of the most important processing
steps performed by CMM. This type of processing does not only require the machine tool technology. To get high quality folds the operator's skills are crucial and even more the company's experience or tradition. CMM, throughout its history, has evolved from family business into an actual industrial company, this transformation phase has helped to develop the production sector that can count on the skills of heads of department specialized in each individual processing type. CMM's team consists of technicians specialized in punching, folding, laser cutting and also in the creation of nesting for punching machines and laser cuts. Talking about folding, CMM operates in this sector with 5 manual machines with numerical control (CNC) and one automatic machine equipped with a robot that performs all the operations required by the folding process. Over the years a large
number of moulds and dies have been purchased, in order to have always the best tool for whatever fold is to be obtained. CMM, beyond
standard folding tools, can also count on a substantial number of special punches and matrices that can be used to
obtain special folds, such as flat, radial and even conical ones. CMM is also equipped with modern software that can simulate the piece to be folded, this system makes it possible to ascertain whether the part designed is
feasible or the purchase of a new mould is required. In recent years, CMM has been equipped with modern 3d
CAD software for solid modelling of surfaces, the application chosen was Solidworks because of its potential and its wide use in technical studios of mechanical parts or metal carpentry designers.
CNC sheet metal foldingFolding is carried out on sheets with a maximum length of 4 m, the power of the machines reach up to 320 tons.

Punching metal sheets up to 1500 x 3000 mm
To carry out such a process CMM is equipped with 2 Amada punching machines with automatic loading and unloading systems. With these machines it is possible to get rather complex processing on materials such as: pickled and galvanized sheets, stainless steel, aluminium, copper and brass. In addition to normal cuts and holes even special products are obtained, such as special air intakes, countersinks, drawings and markings. On many occasions punching turns out to be more competitive than laser cutting, as its operating costs are much lower. Maximum punching cost-effectiveness is obtained when processing low thickness parts and where there are many holes, for example in the field of electrical panels or industrial ventilation.
